Note that we've decided to increase the allocation for 16104 from the originallly planned 2 orbits to 6. The unused targets are included to document the sources that are of specific interest to ULLYSES and for which follow-on spectroscopy is planned. Flash times have been updated to be consistent with the latest recommendations of the WFC3 team. -1285934779 ----- Attempting Submission 1 (Fri Sep 04 17:41:03 GMT 2020) ----- ----- Attempting Submission 2 (Mon Mar 15 19:46:17 GMT 2021) ----- Hello Tricia: Here finally is the phase 2 for 16104.

ULLYSES UV Pre-imaging of Sextans A and NGC 3109 Targets 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 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. This specific program is performing WFC3/UVIS pre-imaging of two low-metallicity galaxies, Sextans A and NGC 3109, where 6 of the ULLYSES targets are located. This pre-imaging in several broadband WFC3/UVIS filters will be used to better constrain the reddening towards the ULLYSES targets and more precisely estimate the exposure times for the follow-up UV spectroscopic observations. This proposal includes pre-imaging of a subset of the massive ULLYSES stars being observed in the low-metallicity nearby galaxies NGC 3109 and Sextans A. The two galaxies will be imaged in 5 filters of WFC3 covering the NUV-NIR. This will allow us to derive stellar photometric catalogs, accurate brightness of the ULLYSES targets in the bluest filter used (F225W) covering the FUV wavelength range and ultimately dust extinction towards the targets. The actual sources for which follow-on ULLYSES spectrocopy is intended are included as unused targets to allow their locations to be easily visulized. Observations in each filters will be taken with a 2-point dither pattern to cover the chip gap, mitigate hot/bad pixels, and better sample the point-spread function for more accurate photometry in crowded fields. Due to the distribution of the ULLYSES stars in NGC 3109, this galaxy will be observed with a mosaic of two pointings. 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-topics-and-programs/ullyses/_documents/HSTUV-report-ULLYSES.pdf. 0 false SUPPORTED GALAXY MAGELLANIC IRREGULAR STAR FORMING REGION tstatus; NGC-3109-V01; P/WFC3 Approved for Submission; S/N/A not started; P/AA 20/07/20; S/xx DD/MM/YY V magnitude was retrieved from the HyperLeda database at: http://leda.univ-lyon1.fr/ledacat.cgi?PGC+029128++++++++++++++++++++ This field contains target NGC3109-E34 (RA = 10h03m14.24s, DEC = -26d09m16.96s) E34 is an O8I(f) with V = 19.61 and E(B-V) = 0.1 Target information is from Evans+2007 (2007ApJ...659.1198E) J2000 GALAXY MAGELLANIC IRREGULAR STAR FORMING REGION tstatus; NGC-3109-V02; P/WFC3 Approved for Submission; S/N/A not started; P/AA 20/07/20; S/xx DD/MM/YY V magnitude was retrieved from the HyperLeda database at: http://leda.univ-lyon1.fr/ledacat.cgi?PGC+029128++++++++++++++++++++ This field contains targets: +++NGC3109-E07 (RA = 10h02m54.69s, DEC = -26d08m59.64s) E07 is a B0-1 Ia with V = 18.69 and E(B-V) = 0.09 +++NGC3109-E20 (RA = 10h03m03.22s, DEC = -26d09m21.41s) E20 is an O8I with V = 19.33 and E(B-V) = 0.17 Target information is from Evans+2007 (2007ApJ...659.1198E) J2000 EXT-STAR B0-B2 III-I NO This object was generated by the targetselector and retrieved from the SIMBAD database.
