This new program, ULLYSES (UV Legacy Library of Young Stars as Essential Standards), will provide a UV spectroscopic reference sample of young (< 10 Myr) 16930( 3) - 09-Apr-2022 00:36:13 - [ 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 includes3 massive stars in Sextans A, to be observed with G140L/800, so as to maximize the wavelength coverage of these faint targets. For all targets, exposure times were computed to reach S/N = 15 at 1130 A. Model spectra for each target were obtained from fitting the WFC3 F225W, F275W, F336W, F475W, and F814W SED from program 16104 with CMFGEN and Castelli & Kurucz (2004) stellar models with LMC Average dust extinction. 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 pics-and-programs/ullyses/_documents/HSTUV-report-ULLYSES.pdf. ------------------------------------------------------------------------------------ 16930( 3) - 09-Apr-2022 00:36:13 - [ 3] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 SEXTANS-A-GH EXT-STAR, MAIN SEQUENCE RA=10H10M58.5800S +/- 0.01", J2000 V = 20.8 F225W Vega=18.606; F275W N-S2 O DEC=-04D43'28.94" +/- 0.01" Vega=18.828; F336W Vega=19.28; F475W Vega=20.88; F814W Vega=20.854 Reference Frame: ICRS Extended: NO Comments: Photometry from program 16104 Spt and E(B-V) originally from Garcia+2019: O3-5Vz; E(B-V) =0.22 Revised/adjusted using WFC3 photometry to O5V with E(B-V) = 0.13 tstatus; SEXTANS-A-GHN-S2; P/COS approved for submission; S/ins N/A; P/JRD 02/08/2022; S/?? 0MM/DD/YYYY) tcheck; APT/SIMBAD target names: [VPW98] 1670 ; Gaia DR2 3779987321206922624; JRD 2/08/22 tcheck; Target info verification status?; complete ; JRD 2/08/22 tcheck; Coordinates & P.M. updated?; yes - Gaia coords - PM set to zero; JRD 2/08/22 tcheck; Adopted SED compared to Observations?; OK ; JRD 2/08/22 ------------------------------------------------------------------------------------------------------------------------------------ 2 SEXTANS-A-GH EXT-STAR, MAIN SEQUENCE RA=10H10M57.8900S +/- 0.05", J2000 V = 20.9 F225W Vega=18.132; F275W N-S4 O DEC=-04D43'10.20" +/- 0.05" Vega=18.453; F336W Vega=19.039; F475W Vega=20.784; F814W Vega=21.141 Reference Frame: ICRS Extended: NO Comments: Photometry from program 16104 Spt and E(B-V) originally from Garcia+2019: O6Vz; E(B-V) =0.05 Revised/adjusted using WFC3 photometry to O6V with E(B-V) = 0.045 tstatus; SEXTANS-A-GHN-S4; P/COS approved for submission; S/ins N/A; P/JRD 02/08/2022; S/?? 0MM/DD/YYYY) tcheck; APT/SIMBAD target names: ; ; JRD 2/08/22 tcheck; Target info verification status?; complete ; JRD 2/08/22 tcheck; Coordinates & P.M. updated?; yes - Coordinates from 2007AJ....133.2393M reported in 2019MNRAS.484..422G - PM set to zero; JRD 2/08/22 tcheck; Adopted SED compared to Observations?; OK ; JRD 2/08/22 ------------------------------------------------------------------------------------------------------------------------------------ 16930( 3) - 09-Apr-2022 00:36:13 - [ 4] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 3 SEXTANS-A-GH EXT-STAR, B0-B2 III-I RA=10H11M5.6800S +/- 0.01", J2000 V = 19.7 F225W Vega=17.526; F275W N-S8 DEC=-04D42'13.64" +/- 0.01" Vega=17.739; F336W Vega=18.191; F475W Vega=19.721; F814W Vega=19.937 Reference Frame: ICRS Extended: NO Comments: Photometry from program 16104 Spt and E(B-V) originally from Garcia+2019: B0 I; E(B-V) =0.05 Revised/adjusted using WFC3 photometry to B0 I with E(B-V) = 0.077 tstatus; SEXTANS-A-GHN-S8; P/COS approved for submission; S/ins N/A; P/JRD 02/08/2022; S/?? 0MM/DD/YYYY) tcheck; APT/SIMBAD target names: [VPW98] 412 ; Gaia DR2 3779987733523729280; JRD 2/08/22 tcheck; Target info verification status?; complete ; JRD 2/08/22 tcheck; Coordinates & P.M. updated?; yes - Gaia coords - PM set to zero; JRD 2/08/22 tcheck; Adopted SED compared to Observations?; OK ; JRD 2/08/22 ------------------------------------------------------------------------------------------------------------------------------------ 16930( 3) - 09-Apr-2022 00:36:13 - [ 5] Visit: 1C Visit Requirements: SCHED 100% On Hold Comments: Additional Comments: vstatus; 1C; SEXTANS-A-GHN-S2; P/COS approved for submission; P/JRD 08/02/22 ; intrev: complete ; P/AF 26/03/22 vcheck; Enter targ name & Inst. & Resp.

The brightest of those is OB523, which was observed as part of GO-14245 (G140L) and GO-15880 (G130M). This is a O9 I star with V = 19.49. This star clears with the ETC under the PSA/MIRRORA configuation, and a Kurucz O9V input model normalized to V = 19.49 without extinction (see COS.ta.1689686). In the FUV, the input spectrum plotted in the ETC in this case is a factor of 2 brighter than the observed G140L spectrum. Therefore, OB121, OB 523 and OB524 are safe to observe with PSA/MIRRORA Exptime computed from model SED that includes stellar emission and dust extinction.
