cds-question@unistra.frwhite-dwarf-starsstellar-massesstellar-agesRevealed by Gaia DR2, the Q branch is a narrow and prominent branch of white dwarf overdensity on the H-R diagram. 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).2019ApJ...886..100Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/886/100CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/625/A87 : Ultra-massive
