Title: Observational Constraints on the White Dwarf Mass-Radius Relation II.
Abstract: We propose to measure gravitational redshifts for white dwarf stars that have distant non-interacting main sequence companions. With independent radius constraints obtained from parallaxes and surface gravity determinations obtained from our spectra, we will make improved estimates of white dwarf masses and radii that can be critically compared with theoretical mass-radius relations specific to each star. These observations will greatly extend the range of masses over which the white dwarf mass-radius relation has been tested, spanning 0.5 to 1.2 solar masses.
