Aero. ------------------------------------------------------------------------------------ Abstract Massive stars are powerful sources of ionizing radiation and kinetic energy that shape the interstellar medium and the UV spectral morphology of host galaxies. Their life-averaged feedback and their end as SN/GRB make them fundamental ingredients to galactic chemodynamical evolution models and population synthesis codes. Feedback from massive stars is not constant along the history of the Universe: their evolution and pre-SN core size is determined to a large extent by radiation-driven winds, and these depend strongly on metallicity. In a Universe of ever-increasing metal content, metal-poor massive stars and their winds are a central piece to study star-forming galaxies in past cosmic epochs. The HST archive, supported by the ULLYSES DDT program, stores a large collection of UV spectra of massive stars in the Milky Way and the Magellanic Clouds that will enable a thorough characterization of radiation-driven winds down to metallicities of 1/5 Zsun. Yet, this value is not representative of the composition of the Universe earlier than redshift=1, nor at such an important landmark as the peak of the Cosmic star formation history (redshift~2). We request HST-COS UV spectroscopy of 4 OB-type stars in Sextans A, with 1/10 Zsun metallicity, akin to blue massive stars of that period. The selection has been crafted to cover uncharted parameter space in the upper HR-diagram, where radiation-driven winds are expected to be significant. Quantitative analysis of this sample together with archival data will allow us to characterize radiation-driven 17111( 2) - 14-Jul-2022 18:42:52 - [ 2] winds at very low metallicity and to produce the first prescriptions to be implemented into models of stellar evolution. ------------------------------------------------------------------------------------ Observations Description ------------------------ General strategy & summary -------------------------- This proposal consists of COS/FUV spectroscopy of 4 O-stars in the dwarf irregular galaxy Sextans A (at ~1Mpc). All targets are visited 3 times in order to accumulate exposure time. Visits have 3 orbits or less to facilitate scheduling. Science exposures: The configuration is COS/FUV, PSA, G140L, TIMETAG, FLASH=YES, CENWAVE=800 and SEGMENT-A (B is off by default). All FP-POS are used, although spread in several orbits/visits. Acquisition strategy: ACQ/IMH We checked that the sources are isolated in a radius of 2'' or that they are brighter than any other target in the r=2'' circle by more than 1 mag in the UV. To this aim we used WFPC3-F225W (preferred) or WFPC3-F275W phot. from program GO-16104 and imaging from Bianchi+ 2012. Source ID, Phot. and astrometric catalogs: ------------------------------------------- Alternate-ID-1 from Massey+ 2007, AJ, 133, 2393 Alternate-ID-2 from Lorenzo, Garcia, Najarro et al. accepted at MNRAS Source for optical photometry: Massey+ 2007, AJ, 133, 2393 Coordinates for the target stars were taken from Gaia eDR3. Estimated exposure times, Buffer times, and UV fluxes (Flux at 1300 Angstroems) ------------------------------------------------------------------------------- --- The listed COS-ETC ID's for spectroscopy correspond to the ETC run with the following parameters. - COS ETC v30.2 - G140L, CENWAVE 800, segment-B HV-low, PSA - EXPTIME=2600s (roughly one full orbit) - Castelli & Kurucz models with the appropriate spectral type - LMC 30Dor supershell extinction law applied before normalization - Normalization by WFC3/UVIS VEGAMAG (F225W or F275W) from program GO-16104 (although exposure times and F_1300 were also calculated with observed V-magnitudes as a double check) These calculations provided - the input spectrum, were the estimated fluxes at 1300\AA were taken from - the buffer fill time (BFT), that was used to estimate the BUFFERTIME=2/3*BFT Extinction E(B-V) was estimated from observed optical UBV photometry, 17111( 2) - 14-Jul-2022 18:42:52 - [ 3] with intrinsic color (B-V)o calculated from the reddening-free Q-pseudo color following the relation by Massey+ 2000. For acquisition ETC quotes, the following parameters were used: - ACQ/IMAGE - PSA, MIRROR-A - GOAL: S/N=20 - With same parameters as above for input stellar spectrum and extinction law. Special requirements: --------------------- None requested. BOT checks: ----------- None of the ETC runs to estimate the exposure times for the spectroscopic science observations or the ACQ/IMAGE, returned any bright-object or count-rate warning. We ran APT's BOT tool, both with GSC2 and GALEX. BOT finds no unsafe objects in either of them. Only GSC2 showed Unknown sources. We queried UV photometry from program GO-16104 around their location and checked that all of them were fainter in the UV than F225W=17.34, F275W=17.62 Since both the GSC2 and GALEX coverage of the field of view is poor in terms of limiting magnitude, and following the recommendation of Sect. 10.4.1 of COS-instrument handbook, we queried UV photometry from program GO-16104 to check whether the targets are clear from Unsafe objects within a 43'' diameter circle. The brightest source found has F225W=16.94, F275W=17.23. This target is Sextans-A-OB523 that was safely observed with COS-G140L in program GO-14245 and with COS-G130M in GO-15880. Nonetheless we checked this source in the ETC with the following parameters: Unreddened Kurucz models for O5V stars High settings for airglow lines and zodiacal light, and extremely high for Earth shine. EXPTIME=2700s for spectroscopy, EXPTIME=10s for ACQ/IMH The count rate did not exceed the recommended values in any case. COS2025 ------- Observations with the G140L gratings are unaffected by the COS2025 policies. IMPACT OF REDUCED GYRO MODE 17111( 2) - 14-Jul-2022 18:42:52 - [ 4] --------------------------- The impact of 2-gyro operations on these observations would be limited since: - The observations are not time critical in any way. - No ORIENT constraints have been requested. - We have arranged the exposures in visits of 3 orbits or less to facilitate scheduling. - Accuracy of pointing is not critical as long as the observatory can ensure that the initial pointing of COS-NUV-ACQ/IMAGE already locates targets within the PSA, and that the COS-ACQ/IMAGE warrants centering the target with the required accuracy. Other points that would impact our program (but just as any other program): - Failed acquisitions, or increased target acquisition time that would reduce the net science exposure time per orbit. REMAINING WARNINGS ---------------------------------- The proposal contains warnings regarding the mandatory use of all FFPOS. Some orbits use only 2 FPPOS, but we arranged the observations to make a balanced use of all 4 FPPOS. ------------------------------------------------------------------------------------ 17111( 2) - 14-Jul-2022 18:42:52 -
