The resulting ``stripped'' helium cores are relatively long-lived, hot, compact, and emit extreme ultraviolet radiation. As a result, they represent a critical piece in our understanding of the ionizing radiation from stellar populations as well as the nature of supernova and gravitational wave progenitors. However, despite their importance and predicted ubiquity, observations have remained elusive. This is now changing. Using UV maps of the Magellanic Clouds, a sample of candidate systems has been identified. Optical spectroscopy reveals stars with temperatures in excess of 60, 000 K, but luminosities intermediate between Wolf-Rayet and subdwarf stars. A lack of strong emission line features indicates their mass loss rates must be more than an order of magnitude lower than previously assumed based on extrapolations from higher luminosity stars. Here, we propose to obtain HST/COS spectra of a sample of 7 of these helium stars in the Magellanic Clouds. UV observations are necessary to measure their mass loss and wind parameters, and this sample was chosen to allow the first observational constraints of these parameters as a function of both luminosity and metallicity. Precise mass loss parameters will have a large impact on the stellar radii, ionizing radiation, and final surface composition of stripped helium stars. These HST/COS observations will therefore provide vital constraints for models of binary evolution, impacting our understanding of supernova progenitors, gravitational wave sources, and ionizing radiation. ------------------------------------------------------------------------------------ Observations Description ------------------------ This program will obtain UV spectra for 7 targets in the LMC/SMC that are newly discovered intermediate mass stripped helium star candididates. These are hot stars that are more luminous than subdwarfs, but lack the wind emission lines of Wolf-Rayet stars. The goal is to obtain UV spectra that can be modeled to constrain their wind parameters and other physical properties. Spectra will be obtained in the FUV with the G140L grism and a center wavelength of 800 AA, providing continuous wavelength coverage between ~900-1950 AA. We use the maximum exposure time avalible in between 1-3 orbits allocated per star, using 16755( 4) - 14-Mar-2022 05:16:21 - [ 2] all four FP positions for each target. The impacts of a reduced gyro operations on this program would primarily be reduced schedualability due to the smaller field of regard, as well as possible impacts of roll angle constraints when avoiding placement of bright field objects in the second COS aperture. Slightly longer acquisition times would have only a small effect on the S/N of our observations. ------------------------------------------------------------------------------------ 16755( 4) - 14-Mar-2022 05:16:21 -
