Detection of the Temperature Dependence of the White Dwarf Mass–Radius Relation with Gravitational Redshifts Open
Models predict that the well-studied mass–radius relation of white dwarf stars depends on the temperature of the star, with hotter white dwarfs having larger masses at a given radius than cooler stars. In this paper, we use a catalog of 26…
