Van Dyke Dixon 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) 16815( 5) - 11-Nov-2022 16:48:10 - [ 2] 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 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 16815( 5) - 11-Nov-2022 16:48:10 - [ 3] http://www.stsci.edu/files/live/sites/www/files/home/stsci-research/research-to pics-and-programs/ullyses/_documents/HSTUV-report-ULLYSES.pdf. ------------------------------------------------------------------------------------ 16815( 5) - 11-Nov-2022 16:48:10 - [ 4] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 N11-ELS-048 STAR, MAIN SEQUENCE O, RA=04H56M58.7979S +/- 0", J2000 V = 14.02 SpT=O6.5 V((f)); E(B-V)=0.10; OF DEC=-66D24'40.84" +/- 0" U=12.87; B=13.85; V=14.02; F1160=6.440e-13 Reference Frame: ICRS Extended: NO Comments: N11-ELS-048 : [ELS2006] N11 048 Previous name : N11-048 Input file: ULLYSES_Cycle29_MassiveStar_ProgramInput_v5.csv SpT = O6.5 V((f)) COS/G130M/c1291 : rn(PoWR-OB-new(PoWR_41000_4.20_m7.00_Z0.50.fits, lmc-ob-i 41-42, Z=0.500 solar, Teff=41000, log_lum=5.13, log_g=4.20, log_mdot=-7.00) (extinction lmcavg=0.100), flux1160 +- 2.0A flux=6.4e-13 Flam) COS/G160M/c1611 : rn(PoWR-OB-new(PoWR_41000_4.20_m7.00_Z0.50.fits, lmc-ob-i 41-42, Z=0.500 solar, Teff=41000, log_lum=5.13, log_g=4.20, log_mdot=-7.00) (extinction lmcavg=0.100), flux1160 +- 2.0A flux=6.4e-13 Flam) Coordinate pedigree: Gaia DR3 Calculation performed 2021-10-25T00:57:19, v0.9 ----------------------------------------------------------- -------------------- tstatus; N11-ELS-048; P/STIS approved for submission; S/ins not started; P/RP 04/08/22; S/xx DD/MM/YY tcheck; APT/SIMBAD target names: ; Simbad name: PGMW-3204; GAIA DR3: 4662152953605873152 tcheck; Target info verification status?; Yes tcheck; Coordinates & P.M. verified, epoch checked?; Yes ... updated to DR3 tcheck; Adopted SED compared to Observations?; Yes ... extinction updated from 0.100 to 0.080 & normalized to the FUSE flux at 1160A Epoch of Position RA proper motion (seconds of time/yr) DEC Proper Motion (arcsec/yr) Annual Parallax (arcsec) 2016 8.502085456430893E-4 -0.0014173454308 0 ------------------------------------------------------------------------------------------------------------------------------------ 16815( 5) - 11-Nov-2022 16:48:10 - [ 5] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 3 N11-ELS-048- STAR, B6-B9.5 V-IV RA=04H56M56.5914S +/- 0", J2000 V = 17.49 OFFSET DEC=-66D24'52.18" +/- 0" Reference Frame: ICRS Extended: NO Comments: This target serves as an offset target for N11-ELS-048 and is located about 17.5" away from N11-ELS-048. An offset target is needed is due to two bright spoiler stars within the 5" checkbox for a STIS ACQ. PGMW 3185 is the brightest object within a 5" radius based on Gaia photometry (Gaia mag=17.395). The only other target (Gaia DR3 4662153022326109056) has a Gaia mag=20.671. To account for any pointing error of up to 1", we investigated two additional nearby targets. Both are also fainter than PGMW 3185: 1) Gaia DR3 4662153022326111360; mag=20.991 and 2) Gaia DR3 4662153022325337088; mag=19.648. We are therefore confident that the correct star will be centered in the STIS aperture before slewing to N11-ELS-048.

For ETC purposes, we used photometry from Parker et al. 1992 which says that PGMW 3185 has V=17.49 and E(B-V) = 0.17. This extinction implies an intrinsic color of (B-V)_0 = -0.21, which is consistent with either a) a B2-B3 dwarf or b) a B0-0.5 I supergiant. By adopting additional calibrations, they estimate Teff = 21.9 kK and log(L/Lsun) = 3.35, which puts it solidly in the B2-B3 V category. A supergiant that belongs to the cluster would be brighter; and the chances of a B supergiant being along the same line of sight but significantly more distant than the cluster is small. Therefore, we use the B3 V Kurucz model in the ETC, reddened by 0.17 and scaled to V=17.49. We expect a S/N ~ 43 with these assumptions. 16815( 5) - 11-Nov-2022 16:48:10 - [ 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 ------------------------------------------------------------------------------------------------------------------------------------ ------------------------------------------------------------------------------------------------------------------------------------ 2 N11-ELS-048 STIS/FUV TIME-TA 0.2X0.2 E140M 1425 WAVECAL=NO, BUFFER-TIME=588 1 2176 S -MAMA G (2176 S) Comments: An updated model was used where the extinction was changed from 0.100 to 0.080 to more closely fit the observed photometry and FUSE data for the ETC run for these observations.
