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 16375( 5) - 05-Jan-2022 15:52:21 - [ 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 16375( 5) - 05-Jan-2022 15:52:21 - [ 3] pics-and-programs/ullyses/_documents/HSTUV-report-ULLYSES.pdf. ------------------------------------------------------------------------------------ 16375( 5) - 05-Jan-2022 15:52:21 - [ 4] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 16375( 5) - 05-Jan-2022 15:52:21 - [ 5] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 AV200 EXT-STAR, B6-B9.5 III-I RA=00H58M7.9080S +/- 0.02", J2000 V = 12.17 SpT=B8Ia; E(B-V)=0.08; DEC=-72D38'30.51" +/- 0.02" U=11.7; B=12.2; V=12.2; F1160=1.34e-13; F1360=8.09e-14; F1700=1.02e-13; F2200=9.20e-14 Reference Frame: ICRS Extended: NO Comments: AV200 : AV_200, AzV200, AzV 200 Previous name : AzV200 Input file: SMC_2020Feb20/input/SMC_all_do1_NewCoords_pids.csv SIMBAD link (AzV 200): https://simbad.u-strasbg.fr/simbad/sim-id?Ident=AzV+200&sub mit=submit+id SpT = B8Ia COS/G130M/c1291 : rn-max(ck04models(B8I, Teff=11278, metallicity=0.004, logG=2.26) (extinction smcbar=0.080), flux1360 +- 30.0A flux=8.1e-14 Flam) COS/G160M/c1611 : rn-max(ck04models(B8I, Teff=11278, metallicity=0.004, logG=2.26) (extinction smcbar=0.080), flux1700 +- 5.0A flux=1e-13 Flam) COS/G185M/c1921 : rn-max(ck04models(B8I, Teff=11278, metallicity=0.004, logG=2.26) (extinction smcbar=0.080), flux1700 +- 5.0A flux=1e-13 Flam) COS/G185M/c1953 : rn-max(ck04models(B8I, Teff=11278, metallicity=0.004, logG=2.26) (extinction smcbar=0.080), flux1700 +- 5.0A flux=1e-13 Flam) COS/G185M/c1986 : rn-max(ck04models(B8I, Teff=11278, metallicity=0.004, logG=2.26) (extinction smcbar=0.080), flux2200 +- 5.0A flux=9.2e-14 Flam) STIS/E140M/c1425 : rn-max(ck04models(B8I, Teff=11278, metallicity=0.004, logG=2.26) (extinction smcbar=0.080), flux1360 +- 30.0A flux=8.1e-14 Flam) STIS/E230M/c1978 : rn-max(ck04models(B8I, Teff=11278, metallicity=0.004, logG=2.26) (extinction smcbar=0.080), flux2200 +- 5.0A flux=9.2e-14 Flam) STIS/E230M/c2707 : rn-max(ck04models(B8I, Teff=11278, metallicity=0.004, logG=2.26) (extinction smcbar=0.080), flux2200 +- 5.0A flux=9.2e-14 Flam) Coordinate pedigree: Gaia Calculation performed 2020-02-24T17:54:58, v0.4 ----------------------------------------------------------- -------------------- tstatus; AV200; P/COS approved for submission; S/STIS approved for submission; P/CP 02/11/20; S/CP 02/11/20 tcheck; APT/SIMBAD target names: ; AV200 'AV 200' ... aka Sk 69 tcheck; Target info verification status?; Done tcheck; Coordinates & P.M. updated?; Verified as good enough (not bothering with proper motions) tcheck; Adopted SED compared to Observations?; OK, ... New STIS G430L spectrum from Massa taken in October 2020 shows a significantly smaller Balmer jump than our adopted model, but original model mostly good enough fit to IUE if locally normalized in wavelength, but E230M c2707 needs to be normalized at a longer wavelength than 2200.. No easy way to manipulate SED to get great overall fit, although a somewhat warmer Teff with a high E(B-V) helps. But if we trust IUE, not really a problem. Note that STIS TA image shows only 1 obvious star in FOV 16375( 5) - 05-Jan-2022 15:52:21 - [ 6] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ ------------------------------------------------------------------------------------------------------------------------------------ 16375( 5) - 05-Jan-2022 15:52:21 - [ 7] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 2 AV314 EXT-STAR, B3-B5 III-I RA=01H02M48.5034S +/- 0.03", J2000 V = 12.87 SpT=B5Iab; E(B-V)=0.00; DEC=-72D16'45.41" +/- 0.03" U=11.98 B=12.82; V=12.93; I=13.05; F1160=1.85e-13; F1360=1.78e-13; F1700=1.48e-13; F2200=1.03e-13 Reference Frame: ICRS Extended: NO Comments: AV314 : AV_314, AzV314, AzV 314 Previous name : AzV314 Input file: SMC_2020Feb20/input/SMC_all_do1_NewCoords_pids.csv SIMBAD link (AzV 314): https://simbad.u-strasbg.fr/simbad/sim-id?Ident=AzV+314&sub mit=submit+id SpT = B5Iab COS/G130M/c1291 : rn-max(ck04models(B5I, Teff=13600, metallicity=0.004, logG=2.5), flux1360 +- 30.0A flux=1.8e-13 Flam) COS/G160M/c1611 : rn-max(ck04models(B5I, Teff=13600, metallicity=0.004, logG=2.5), flux1700 +- 5.0A flux=1.5e-13 Flam) COS/G185M/c1921 : rn-max(ck04models(B5I, Teff=13600, metallicity=0.004, logG=2.5), flux1700 +- 5.0A flux=1.5e-13 Flam) COS/G185M/c1953 : rn-max(ck04models(B5I, Teff=13600, metallicity=0.004, logG=2.5), flux1700 +- 5.0A flux=1.5e-13 Flam) COS/G185M/c1986 : rn-max(ck04models(B5I, Teff=13600, metallicity=0.004, logG=2.5), flux2200 +- 5.0A flux=1e-13 Flam) STIS/E140M/c1425 : rn-max(ck04models(B5I, Teff=13600, metallicity=0.004, logG=2.5), flux1360 +- 30.0A flux=1.8e-13 Flam) STIS/E230M/c1978 : rn-max(ck04models(B5I, Teff=13600, metallicity=0.004, logG=2.5), flux2200 +- 5.0A flux=1e-13 Flam) STIS/E230M/c2707 : rn-max(ck04models(B5I, Teff=13600, metallicity=0.004, logG=2.5), flux2200 +- 5.0A flux=1e-13 Flam) Coordinate pedigree: Gaia Calculation performed 2020-02-24T17:54:08, v0.4 ----------------------------------------------------------- -------------------- tstatus; AV314; P/COS approved for submission; S/STIS approved for submission; P/CP 02/11/20; S/DW 22/05/21 tcheck; APT/SIMBAD target names: ; AV314 'AV 314' tcheck; Target info verification status?; good tcheck; Coordinates & P.M. updated?; Verified (not including proper motions) tcheck; Adopted SED compared to Observations?; yes ...
