Welty Space Telescope Science Institute N ------------------------------------------------------------------------------------ Abstract The Space Telescope Science Institute (STScI) Director has decided to devote up to 1000 orbits of Director's Discretionary time in observing Cycles 27-29 to a new Hubble Ultraviolet Legacy program focused on star formation and associated stellar physics. This new program, ULLYSES (UV Legacy Library of Young Stars as Essential Standards), will provide a UV spectroscopic reference sample of young (< 10 Myr) high- and low-mass stars. It will target over ~150 OB stars in the Magellanic Clouds and lower metallicity galaxies in the Local Group, and ~40 T Tauri stars and brown dwarfs in the Milky Way. In addition, ULLYSES will monitor 4 typical T Tauri stars over different rotational phases through at least three rotation periods, and over 16370( 6) - 21-Apr-2022 12:51:05 - [ 2] timescales of months to years. The resulting library will provide template spectra of massive stars at metallicities substantially below the well studied, while the low mass sample will cover a wide range of ages, accretion rates, and masses, including objects down to well below 0.5 M_sun. The legacy of this large UV dataset on the first 10 Myr of stellar evolution will be enhanced by complementary datasets obtained by the scientific community. In addition to the core goals of the program related to stellar astrophysics of low and high mass stars, this data will also enable exciting science in the fields of ISM, CGM, jets, and exoplanets. ULLYSES will be modeled after the Frontier Fields program: all data obtained will be non-proprietary. The implementation team at STScI is developing high-level science data products and a sophisticated database and website for disseminating data from the ULLYSES program and ancillary datasets for the ULLYSES target sample from space and ground-based facilities. ------------------------------------------------------------------------------------ Observations Description ------------------------ This proposal includes a subset of the massive ULLYSES stars being observed in the Magellanic clouds. Depending on target brightness, the main FUV spectral range will generally use either the STIS E140M setting or the combination of the COS c1291 + c1611 settings. Sufficiently bright stars without good FUSE data in the archive will also be observed with the COS c1096 setting to provide coverage at shorter wavelengths. Where time permits, stars of type O9 or later will also be observed with STIS E230M/1978, while for supergiants of spectral type B5 or later E230M/2707 may also be included. Where possible, targets of a given spectral type were selected to span both a range in extinction and in rotation rates to support a variety of stellar and ISM studies. Signal-to-noise requirements used to determine the desired exposures times were defined as follows: COS/G130M/c1096: 20 / nine-pixel resel at 1080 A COS/G130M/c1291: 30 / six-pixel resel at 1150 A COS/G160M/c1611: 30 / six-pixel resel at 1590 A COS/G185M/c1953: 30 / three-pixel resel at 1860 A COS/G185M/c1986: 30 / three-pixel resel at 1980 A STIS/E140M/c1425: 20 / two-pixel resel at 1200 A STIS/E230M/c1978: 20 / two-pixel resel at 1800 A STIS/E230M/c2707: 20 / two-pixel resel at 2800 A The actual implemented exposure times may be adjusted to efficiently use HST orbits, but should always provide at least 80% of the desired time as defined by the above requirements.

PoWR models were selected according to the nominal SpT-Teff calibration for O7 I and O7 III classifications to bracket the OC7 II(f) classification of 2dFS 2266. For both models, the flux was scaled to the distance of the SMC and attenuated by an SMCbar extinction law with E(B-V) = 0.02 (2002ApJS..141...81M). The flux associated with both models had to be reduced substantially to match the available UBV photometry, which suggests that the star is less luminous (i.e., has a smaller radius) than modeled. A model corresponding to an O7 III star with flux reduced by a factor of 0.14 was ultimately adopted. It corresponds to the file: PoWR_36000_3.60_m6.76_Z0.14_smcbar_ebmv_0.02_sed.fits Adopted illustrated: ~/box/ullyses_tech/ullyses_proposals/c28_mc/16370/2DFS-2266 /2DFS-2266_adopted_sed_vs_UBV.png Adopted SED: ~/box/ullyses_tech/ullyses_proposals/c28_mc/16370/2DFS-2266 /2DFS-2266_adopted_sed.fits The far-UV flux is uncertain because (a) the normalization is set by UBV photometry; and (b) the star is evidently only lightly reddened. 16370( 6) - 21-Apr-2022 12:51:05 - [ 5] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ ------------------------------------------------------------------------------------------------------------------------------------ 16370( 6) - 21-Apr-2022 12:51:05 - [ 6] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 2 2DFS-3954 EXT-STAR, MAIN SEQUENCE RA=01H30M43.1080S +/- 0", J2000 V = 15.27 SpT=O6 V((f))z; E(B-V)=0.02; O, OF DEC=-73D25'4.14" +/- 0" U=13.93; B=15.01; V=15.27 Reference Frame: ICRS Extended: NO Comments: 2DFS-3954 : [2dFS]-3954, [2dFS]_3954, 2dFS 3954 Previous name : [2dFS]-3954 Input file: SMC_2020Feb20/input/SMC_all_do1_NewCoords_pids.csv SIMBAD link (2dFS 3954): https://simbad.u-strasbg.fr/simbad/sim-id?Ident=2dFS+3954&s ubmit=submit+id SpT = O6 V((f))z COS/G130M/c1096 : rn(WM-Basic(O7 V, Z=0.004, Teff=39811, log_lum=5.42, log_g=4.00) (extinction smcbar=0.020), johnson U mag=13.930 vegamag) COS/G130M/c1291 : rn(WM-Basic(O7 V, Z=0.004, Teff=39811, log_lum=5.42, log_g=4.00) (extinction smcbar=0.020), johnson U mag=13.930 vegamag) COS/G160M/c1611 : rn(WM-Basic(O7 V, Z=0.004, Teff=39811, log_lum=5.42, log_g=4.00) (extinction smcbar=0.020), johnson U mag=13.930 vegamag) COS/G185M/c1921 : rn(WM-Basic(O7 V, Z=0.004, Teff=39811, log_lum=5.42, log_g=4.00) (extinction smcbar=0.020), johnson U mag=13.930 vegamag) COS/G185M/c1953 : rn(WM-Basic(O7 V, Z=0.004, Teff=39811, log_lum=5.42, log_g=4.00) (extinction smcbar=0.020), johnson U mag=13.930 vegamag) COS/G185M/c1986 : rn(WM-Basic(O7 V, Z=0.004, Teff=39811, log_lum=5.42, log_g=4.00) (extinction smcbar=0.020), johnson U mag=13.930 vegamag) STIS/E140M/c1425 : rn(WM-Basic(O7 V, Z=0.004, Teff=39811, log_lum=5.42, log_g=4.00) (extinction smcbar=0.020), johnson U mag=13.930 vegamag) STIS/E230M/c1978 : rn(WM-Basic(O7 V, Z=0.004, Teff=39811, log_lum=5.42, log_g=4.00) (extinction smcbar=0.020), johnson U mag=13.930 vegamag) STIS/E230M/c2707 : rn(WM-Basic(O7 V, Z=0.004, Teff=39811, log_lum=5.42, log_g=4.00) (extinction smcbar=0.020), johnson U mag=13.930 vegamag) Coordinate pedigree: Gaia Calculation performed 2020-02-24T17:57:32, v0.4 ----------------------------------------------------------- -------------------- tstatus; 2DFS-3954; P/COS approved for submission; S/ins not started; P/AF 20/08/20; S/xx DD/MM/YY tcheck; APT/SIMBAD target names: ; 2DFS-3954; "2dFS 3954" tcheck; Target info verification status?; Verified ...

A PoWR model was selected according to the nominal SpT-Teff calibration: (Teff, logg, logMdot, Z/Zsun) = (37000, 4.00, -7.13, 0.14). The model flux was scaled to the distance of the SMC and attenuated by an SMCbar extinction law with E(B-V) = 0.03 (2002ApJS..141...81M). A good match to the observed IUE/SWP and IUE/LWP fluxes and UBV photometry required a reduction in the overall flux level by a factor of 0.5. An equally good match was obtained by using a model with a slightly larger logg of 4.20. Since this model is for a more compact object, its flux only required reduction by a factor of 0.9 to achieve the match. The adopted SED corresponds to the file: PoWR_37000_4.20_m7.26_Z0.14_smcbar_ebmv_0.03_sed.fits. The parameters of this model agree closely with those determined by Ramachandran et al.

Default name in SIMBAD is "SMC AB 9" tcheck; Target info verification status?; Verified tcheck; Coordinates & P.M. updated?; 2MASS J2000 tcheck; Adopted SED compared to Observations?; Yes ... The detailed analysis of the spectrum of 2dFS 999 = SMC AB 9 by Hainich et al. (2015A&A...581A..21H) provided the starting point for the selection of a model spectrum. A model with very similar parameters to those determined by Hainich et al. was selected from the PoWR grid for WR stars with SMC metallicity and a hydrogen abundance of 0.40 by mass. The model flux was scaled to the distance of the SMC and attenuated by an SMCbar extinction law with E(B-V) = 0.07. This reddening is slightly lower than the value derived by Hainich et al. (0.095), but well within the uncertainties of the photometry. An additional scaling factor of 3.3 was required to get a good match to the available FUSE spectrum and UBV photometry, and is presumably an indication that the luminosity of the model does not exactly match the luminosity of 2dFS 999. As noted by Hainich et al., the continuum flux level of the FUSE spectrum of 2dFS 999 changes abruptly by a factor of about two for wavelengths shorter than 1000 Angstroms, most likely because the SiC channels were not well aligned at the time of the observation. Consequently, only wavelengths longer than 1000 Angstroms were considered when selecting the model atmosphere. Contamination from other sources within the LWRS aperture may also be an issue, though most of these targets appear to be late-type stars. 2dFS 999 may be in a binary system with an O-type companion, but no allowance was made for this possibility when selecting the spectrum. The adopted SED corresponds to the file PoWR_100000_5.17_m5.58_Z0.14_smcbar_ebmv_0.07_sed.fits.

A PoWR model was selected according to the nominal SpT-Teff calibration: (Teff, logg, logMdot, Z/Zsun) = (37000, 4.00, -7.13, 0.14). The model flux was scaled to the distance of the SMC and attenuated by an SMCbar extinction law with E(B-V) = 0.09 (2002ApJS..141...81M). Although it provided a good baseline fit to the available IUE low dispersion spectra and UBV photometry, an improved fit to the SWP spectrum was found with a slightly reduced reddening of E(B-V) = 0.06. This value is well within the uncertainty of the photometric measurements. The adopted SED corresponds to the file PoWR_37000_4.00_m7.13_Z0.14_smcbar_ebmv_0.06_sed.fits.

Some tinkering was required to insert a target acquisition into the plan. 2) The dispersed light TA was changed from G130M/1291 to G160M/1611. The exposure times for this configuration were recalcuated, and changed from 0.4s to 0.7 s (rounded to 1 s). The ETC calculation ID was updated for both ACQ exposures (BC.001 and BC.002). 3) The buffer times for FP-POS3 and 4 with G160M/1611 (exposures BC.003 and BC.004) was optimized by reducing it from 645s to 350 s. 4) To avoid having a very unbalanced distribution of exposure across the 4 FP-POS of the G130M/1096 configuration, the next exposure was re-distributed across sub-exposures and buffer times were re-optimized to yield a net exposure time of 5594 s distributed as (1399 s, 1399 s, 1398 s, 1398 s) for the 4 FP-POS. ETC calculation COS.sp.1533467 predicts predicts SNR = 18.2 /resel at 1080 A in 5594 s.

The buffer time for the first exposure was reset to 491s. 4) As a result, the 4 sub-exposures for the G130M/1096 spectrum are slightly unbalanced: (1312 s, 1600s, 1400s, 1396s). 5) The SNR of the COS/G130M spectrum at the fiducial wavelength of 1070 Angstroms is predicted to be 15.8 per resel. 6) Allocated COS orbits for Visit IC = 1 Exposures ------------------------------------------------------------------------------------------------------------------------------------ Exp | Target | Instr | Oper. | Aper |Spectral|Central| Optional |Num| Time | Special Num | Name | Config | Mode | or FOV |Element |Waveln.| Parameters |Exp| (Total) | Requirements ------------------------------------------------------------------------------------------------------------------------------------ 16370( 6) - 21-Apr-2022 12:51:05 - [ 92] Exposures ------------------------------------------------------------------------------------------------------------------------------------ Exp | Target | Instr | Oper. | Aper |Spectral|Central| Optional |Num| Time | Special Num | Name | Config | Mode | or FOV |Element |Waveln.| Parameters |Exp| (Total) | Requirements ------------------------------------------------------------------------------------------------------------------------------------ 1 AV251 COS/FUV ACQ/PEA PSA G130M 1291 CENTER=FLUX-WT, NUM-POS=3, 1 0.3 S (0.3 KXD STEP-SIZE=1.3, SEGMENT=BOTH S) Comments: SED PoWR_37000_4.00_m7.13_Z0.14_smcbar_ebmv_0.06_ sed ~/box/ullyses_tech/ullyses_proposals/c28_mc/1 6370/AV251/AV251_adopted_sed.fits ETC estimates that SNR=40 is obtained for Segments A and B combined in 0.2621 s per dwell point.

The buffer times were adjusted to pack the orbits efficiently. 4) Allocated COS orbits for Visit KC = 2, though only ~1.75 are required to replace the exposures lost during Visit FC. Accordingly, the 2nd orbit is not filled. 3) Allocated COS orbits for visit FC = 3 Exposures ------------------------------------------------------------------------------------------------------------------------------------ Exp | Target | Instr | Oper. | Aper |Spectral|Central| Optional |Num| Time | Special Num | Name | Config | Mode | or FOV |Element |Waveln.| Parameters |Exp| (Total) | Requirements ------------------------------------------------------------------------------------------------------------------------------------ 16370( 6) - 21-Apr-2022 12:51:05 - [ 98] Exposures ------------------------------------------------------------------------------------------------------------------------------------ Exp | Target | Instr | Oper. | Aper |Spectral|Central| Optional |Num| Time | Special Num | Name | Config | Mode | or FOV |Element |Waveln.| Parameters |Exp| (Total) | Requirements ------------------------------------------------------------------------------------------------------------------------------------ 1 2DFS-2266 COS/FUV ACQ/PEA PSA G130M 1291 CENTER=FLUX-WT, NUM-POS=3, 1 0.5 S (0.5 KXD STEP-SIZE=1.3, SEGMENT=BOTH S) Comments: SED PoWR_36000_3.60_m6.76_Z0.14_smcbar_ebmv_0.02_ sed; includes a reduction in the model flux by a factor of 0.14. ~/box/ullyses_tech/ullyses_proposals/c28_mc/1 6370/2DFS-2266/2DFS-2266_adopted_sed.fits ETC estimates that SNR = 40 is obtained for Segments A and B combined in 0.3004 s per dwell point.
