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 16825( 3) - 29-Aug-2022 15:48:49 - [ 2] 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 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. Additional details about the scientific motivation and technical implementation strategy of the ULLYSES observations can be found at http://www.stsci.edu/stsci-research/research-topics-and-programs/ullyses. The ULLYSES program is based on the recommendations of a working group led by Sally Oey; the full text of that group's report can be found at http://www.stsci.edu/files/live/sites/www/files/home/stsci-research/research-to 16825( 3) - 29-Aug-2022 15:48:49 - [ 3] pics-and-programs/ullyses/_documents/HSTUV-report-ULLYSES.pdf. ------------------------------------------------------------------------------------ 16825( 3) - 29-Aug-2022 15:48:49 - [ 4] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 SK-66D152 STAR, SUPERGIANT O, OF RA=05H34M18.7262S +/- 0", J2000 V = 12.58 SpT=O7 Ib(f); E(B-V)=0.07; DEC=-66D08'42.25" +/- 0" U=11.33; B=12.38; V=12.58; F1160=1.590e-12; F1360=1.250e-12; F1700=7.440e-13; F2200=4.510e-13 Reference Frame: ICRS Extended: NO Comments: SK-66D152 : SK -66 152 Previous name : Sk -66 152 Input file: ULLYSES_Cycle29_MassiveStar_ProgramInput_v5.csv SpT = O7 Ib(f) COS/G130M/c1096 : rn(PoWR-OB-new(PoWR_35000_3.40_m7.00_Z0.50.fits, lmc-ob-i 35-34, Z=0.500 solar, Teff=35000, log_lum=5.91, log_g=3.40, log_mdot=-7.00) (extinction lmcavg=0.070), flux1160 +- 2.0A flux=1.6e-12 Flam) Coordinate pedigree: Gaia DR2 Calculation performed 2021-10-25T01:01:12, v0.9 ----------------------------------------------------------- -------------------- tstatus; SK-66D152; P/COS approved for submission; S/STIS complete; P/WVD 20/07/22; S/JRD 26/08/22 tcheck; APT/SIMBAD target names: ; HD 271366, 2MASS J05341873-6608422 tcheck; Target info verification status?; OK tcheck; Coordinates & P.M. verified, epoch checked?; Yes.

This prediction is fairly robust given the existence of an archival IUE spectrum. While the screening limit for COS is 15, 000 cts/s for one segment, the actual limit is 30, 000 cts/s for both segments combined. High count rates are only problematic above 21, 000 cts/s due to dead time issues. So for this target, we can safely set up the observations with SEGMENT = BOTH. This will avoid the rather long wavelength gap between 1096/FUVB and the STIS spectrum and will maximize the archival value of the spectrum. The BUFFER-TIME should be 94 seconds, but using values less than 111 seconds causes APT to truncate the exposure at twice the buffer time, so I have set BUFFER-TIME to 111 seconds. The buffer time output in the ETC is 141s, so we still have a 25% margin in target brightness before data starts getting lost. Given that the SED was constrained with an IUE spectrum, this should be conservative enough. 16825( 3) - 29-Aug-2022 15:48:49 - [ 8] Exposures ------------------------------------------------------------------------------------------------------------------------------------ Exp | Target | Instr | Oper. | Aper |Spectral|Central| Optional |Num| Time | Special Num | Name | Config | Mode | or FOV |Element |Waveln.| Parameters |Exp| (Total) | Requirements ------------------------------------------------------------------------------------------------------------------------------------ ------------------------------------------------------------------------------------------------------------------------------------ 16825( 3) - 29-Aug-2022 15:48:49 - [ 9] Exposures ------------------------------------------------------------------------------------------------------------------------------------ Exp | Target | Instr | Oper. | Aper |Spectral|Central| Optional |Num| Time | Special Num | Name | Config | Mode | or FOV |Element |Waveln.| Parameters |Exp| (Total) | Requirements ------------------------------------------------------------------------------------------------------------------------------------ 3 SK-66D152 COS/FUV TIME-TA PSA G130M 1096 FP-POS=2, BUFFER-TIME=111 1 959 S (959 G S) Comments: rn(PoWR-OB-new(PoWR_35000_3.40_m7.00_Z0.50.fi ts, lmc-ob-i 35-34, Z=0.500 solar, Teff=35000, log_lum=5.91, log_g=3.40, log_mdot=-7.00) (extinction lmcavg=0.070), flux1160 +- 2.0A flux=1.6e-12 Flam); cos, fuv, g130m, c1096, psa, mjd#59670; fp-pos=None, segment=None) From file ULLYSES_Cycle29_MassiveStar_ProgramInput_v5.c sv Spectral type: O7 Ib(f) SED = SK-66D152_COS_G130M_c1096_sed.fits For exptime=1108.4 s, spectral region: 1080.0 +- 0.5 A achieves SNR=20.0/resel global countrate (brightest segment): 17129.7 cts/s/segment brightest pixel: 0.344 cts/s/pix at 1216.5 A Calculation performed 2021-10-25T01:01:18, v0.9 == All ETC calculations were performed with the model sk66d152_sed_new.fits, a PoWR model scaled to match the observed flux at 1360 A.

Given that the SED was constrained with an IUE spectrum, this should be conservative enough. 16825( 3) - 29-Aug-2022 15:48:49 - [ 14] Exposures ------------------------------------------------------------------------------------------------------------------------------------ Exp | Target | Instr | Oper. | Aper |Spectral|Central| Optional |Num| Time | Special Num | Name | Config | Mode | or FOV |Element |Waveln.| Parameters |Exp| (Total) | Requirements ------------------------------------------------------------------------------------------------------------------------------------ ------------------------------------------------------------------------------------------------------------------------------------ Sub Exposures ------------------------------------------------------------------------------------------------------------------------------------ Target | Exp |Instr | Oper. | Aper |Spectral|Cent.|Primary |Secondary |Iteration |CR-SPLIT |Orbit |Duration Name | Num |Config | Mode | or FOV |Element |Wave.|Pattern Pos |Pattern Pos |Num |Num |Number | ------------------------------------------------------------------------------------------------------------------------------------ SK-66D152 1 COS/NUV ACQ/IMA BOA MIRRORB none none none none 1 N/A GE SK-66D152 2 COS/FUV TIME-TA PSA G130M 1096 none none none none 1 N/A G SK-66D152 3 COS/FUV TIME-TA PSA G130M 1096 none none none none 1 N/A G SK-66D152 4 COS/FUV TIME-TA PSA G130M 1096 none none none none 2 N/A G SK-66D152 5 COS/FUV TIME-TA PSA G130M 1096 none none none none 2 N/A G 16825( 3) - 29-Aug-2022 15:48:49 - [ 15] Visit: 1S (SK-66D152-STIS) Visit Requirements: SCHED 100% On Hold Comments: Additional Comments: vstatus; 1S; SK-66D152; S/STIS approved for submission; S/DW 30/12/21 ; intrev: complete ; P/JRD 26/08/22 vcheck; Enter targ name & Inst. & Resp.
