PI: Mr. John P. Subasavage Georgia State University Research Foundation CoI: Dr. Hektor Monteiro Georgia State University Research N Foundation CoI: Dr. Wei-Chun Jao Georgia State University Research N Foundation CoI: Dr. Todd J. Henry Georgia State University Research N Foundation CoI: Dr. Edmund Nelan Space Telescope Science Institute N ------------------------------------------------------------------------------------ Abstract We propose to use HST/FGS1R to determine White Dwarf (WD) masses. The unmatched resolving power of HST/FGS1R will be utilized to follow up four selected WD binary pairs. This high precision obtained with HST/FGS1R simply cannot be equaled by any ground based technique. This proposed effort complements that done by CoI Nelan in which a sample of WDs is being observed with HST/FGS1R. This proposal will dramatically increase the number of WDs for which dynamical mass measurements are possible, enabling a better calibration of the WD mass-radius relation, cooling curves, initial to final mass relations, and ultimately giving important clues to the star formation history of our Galaxy and the age of its disk as well as in other galaxies. (This project is part of Subasavage's PhD thesis work at Georgia State University.) ------------------------------------------------------------------------------------ Observations Description ------------------------ We will use FGS1r in its high angular resolution TRANSFER mode to observe our targets. Each single-orbit visit will contain two exposures, one with a long scan path, one with a short scan path. This will provide sensitivity for both wide binaries as well as close systems. The wide-band F583W filter will be used to maximize photon throuput.
