Fundamental parameter accuracy of DA and DB white dwarfs in Gaia Data Release 2
P. -E. Tremblay, E. Cukanovaite, N. P. Gentile Fusillo +2
We report on a comparison of spectroscopic analyses for hydrogen (DA) and helium atmosphere (DB) white dwarfs with Gaia Data Release 2 (DR2) parallaxes and photometry. We assume a…
The White Dwarf Initial-Final Mass Relation for Progenitor Stars From 0.85 to 7.5 M
Jeffrey D. Cummings, Jason S. Kalirai, P. -E. Tremblay +2
We present the initial-final mass relation (IFMR) based on the self-consistent analysis of Sirius B and 79 white dwarfs from 13 star clusters. We have also acquired additional sign…
A Data Release 2 catalogue of white dwarfs and a comparison with SDSS
Nicola Pietro Gentile Fusillo, Pier-Emmanuel Tremblay, Boris T. Gänsicke +11
We present a catalogue of white dwarf candidates selected from the second data release of (DR2). We used a sample of spectroscopically confirmed white dwarfs from the Sloan…
The Gaia 20 pc white dwarf sample
M. A. Hollands, P. E. Tremblay, B. T. Gaensicke +2
Using Gaia DR2 data, we present an up-to-date sample of white dwarfs within 20 pc of the Sun. In total we identified 139 systems in Gaia DR2, nine of which are new detections, with…
