High-mass white dwarfs in Gaia DR2
Listed in IVOA Registry (Virtual Observatory)
Revealed by Gaia DR2, the Q branch is a narrow and prominent branch of white dwarf overdensity on the H-R diagram.
Description
We find that there are significantly more fast-moving white dwarfs on the Q branch, which have very old true ages but young photometric ages. This age discrepancy suggests a cooling anomaly in some white dwarfs on the Q branch, posing a challenge to current white dwarf cooling models.
We tabulate the information of nearby high-mass white dwarfs (d<250, 1.08<m_WD<1.23), which is used to investigate the Q branch and its physical origin in Cheng et al. (2019). This table contains the WD name, photometry and astrometry from Gaia DR2, H-R diagram coordinates and transverse velocity that we derive, and spectral information from Montreal White Dwarf Database (MWDD).
