TL;DR
This paper presents a comprehensive catalogue of approximately 359,000 high-confidence white dwarf candidates from Gaia EDR3, including stellar parameters and spectral classifications, enhancing the understanding of white dwarf populations.
Contribution
The study introduces a new, large-scale white dwarf catalogue from Gaia EDR3 with improved selection criteria, probability assessments, and spectral classifications, building upon previous Gaia DR2 work.
Findings
Catalogue includes ~359,000 high-confidence white dwarf candidates.
Achieves up to 93% completeness for certain white dwarfs.
Provides stellar parameters and spectral classifications for the candidates.
Abstract
We present a catalogue of white dwarf candidates selected from Gaia early data release three (EDR3). We applied several selection criteria in absolute magnitude, colour, and Gaia quality flags to remove objects with unreliable measurements while preserving most stars compatible with the white dwarf locus in the Hertzsprung-Russell diagram. We then used a sample of over 30 000 spectroscopically confirmed white dwarfs and contaminants from the Sloan Digital Sky Survey (SDSS) to map the distribution of these objects in the Gaia absolute magnitude-colour space. Finally, we adopt the same method presented in our previous Gaia DR2 work to calculate a probability of being a white dwarf (Pwd) for 1.3 million sources which passed our quality selection. The Pwd values can be used to select a sample of 359 000 high-confidence white dwarf candidates in the magnitude range 8< G <21.…
