The Initial-to-final Mass Relation of White Dwarfs in Intermediate-separation Binaries

The Initial-to-final Mass Relation of White Dwarfs in Intermediate-separation Binaries

We examine the applicability of the initial-to-final mass relation (IFMR) for white dwarfs (WDs) in intermediate-separation binary systems (∼1 au), using astrometric binaries identified in open clusters from Gaia DR3. A careful analysis of the astrometric orbits and spectral energy distributions iso...
