Kinematic and Dynamical Properties of Solar Neighborhood White Dwarfs from SDSS DR19 and Gaia DR3
The study analyzed 5,837 DA white dwarfs using SDSS and Gaia data to map their kinematics and dynamics within the Milky Way. The findings show that these white dwarfs are overwhelmingly part of the thin disk, with minor contributions from the thick disk and halo. The analysis confirms that white dwarfs preserve the dynamical heating history of the Galactic disk over long timescales.
