cds-question@unistra.frwhite-dwarf-starshalo-starsvisible-astronomytrigonometric-parallaxproper-motionstwo-color-diagramsnarrow-band-photometrystellar-spectral-typesWe present a catalog of 531 white dwarf candidates that have large apparent transverse motions relative to the Sun (v_T_>200km/s), thus making them likely members of the local Galactic halo population. The candidates were selected from the Gaia Data Release 2 and are located in a great circle with 20{deg} width running across both Galactic poles and the Galactic center and anticenter, a zone that spans 17.3% of the sky. The selection used a combination of kinematic and photometric properties, derived primarily from Gaia proper motions, G magnitudes, and G_BP_-G_RP_ color, and including parallax whenever available. Additional validation of the white dwarf candidates is made using PanSTARRS photometric (gri) data. Our final catalog includes not only stars having full kinematic and luminosity estimates from reliable Gaia parallax, but also stars with presently unreliable or no available Gaia parallax measurements. We argue that our method of selecting local halo objects with and without reliable parallax data leads us to round up all possible halo white dwarfs in the Gaia catalog (in that particular section of the sky) with recorded proper motions >40mas/yr and that pass our v_T_>200km/s threshold requirement. We expect this catalog will be useful for the study of the white dwarf population of the local Galactic halo.2020ApJ...899...83Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/899/83CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/207 : Palomar-Green catalog UV-excess stellar objects (Green+, 1986)III/210 : Spectroscopically Identified White Dwarfs (McCook+, 1999)III/235 : Spectroscopically Identified White Dwarfs (McCook+, 2008)I/337 : Gaia DR1 (Gaia Collaboration, 2016)I/345 : Gaia DR2 (Gaia Collaboration, 2018)VII/223 : The 2dF QSO Redshift Survey.
