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…
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…
Anatomy of the hyper-runaway star LP 40-365 with Gaia
R. Raddi, M. A. Hollands, B. T. Gaensicke +4
LP 40-365 (aka GD 492) is a nearby low-luminosity hyper-runaway star with an extremely unusual atmospheric composition, which has been proposed as the remnant of a white dwarf that…
Further insight on the hypervelocity white dwarf, LP 40-365 (GD 492): a nearby emissary from a single-degenerate Type Ia supernova
R. Raddi, M. A. Hollands, D. Koester +4
The recently discovered hypervelocity white dwarf LP 40-65 (aka GD 492) has been suggested as the outcome of the failed disruption of a white dwarf in a sub-luminous Type Ia supern…
Cool DZ white dwarfs II: Compositions and evolution of old remnant planetary systems
Mark Hollands, Boris Gaensicke, Detlev Koester
In a previous study, we analysed the spectra of 230 cool ( < 9000 K) white dwarfs exhibiting strong metal contamination, measuring abundances for Ca, Mg, Fe and in…
