Orbit allocation needs to be updated to 9 orbitsULLYSES NGC 3109 COS SpectroscopyThe 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 proposal includes3 massive stars in NGC3109, 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 1) the BEAST code (Gordon+2016), and 2) CMFGEN stellar models with LMC Average dust extinction. In the first case, the BEAST code output predictions for UV fluxes at 1080, 1150, 1200, 1590 and 1800A. These fluxes were within a factor of 2 of those values were obtained from fitting the WFC3 SED to CMFGEN + extinction models (with the BEAST fluxes usually lower than the CMFGEN fluxes). The exposure time was selected based on the maximum exposure time from these two ETC calculations, i.e., from the BEAST fluxes.
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-topics-and-programs/ullyses/_documents/HSTUV-report-ULLYSES.pdf.6falsefalsefalsefalsefalsefalsefalseSUPPORTEDEXT-STARSUPERGIANT ONOFrom 2007ApJ...659.1198E (Evans+2007)
