white dwarfs within 40 pc III: spectroscopic observations of new candidates in the southern hemisphere
Mairi W. O'Brien, P. -E. Tremblay, N. P. Gentile Fusillo +31
We present a spectroscopic survey of 248 white dwarf candidates within 40 pc of the Sun; of these 244 are in the southern hemisphere. Observations were performed mostly with the Ve…
A catalogue of white dwarfs in Gaia EDR3
N. P. Gentile Fusillo, P. -E. Tremblay, E. Cukanovaite +7
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 q…
Horizontal spreading of planetary debris accreted by white dwarfs
Tim Cunningham, Pier-Emmanuel Tremblay, Evan B. Bauer +8
White dwarfs with metal-polluted atmospheres have been studied widely in the context of the accretion of rocky debris from evolved planetary systems. One open question is the geome…
3D spectroscopic analysis of helium-line white dwarfs
Elena Cukanovaite, Pier-Emmanuel Tremblay, Pierre Bergeron +3
In this paper, we present corrections to the spectroscopic parameters of DB and DBA white dwarfs with -10.0 < log(H/He) < -2.0, 7.5 < log(g) < 9.0 and 12000 K < T_eff < 34000 K, ba…
Doppler beaming factors for white dwarfs, main sequence stars, and giant stars Limb-darkening coefficients for 3D (DA and DB) white dwarf models
A. Claret, E. Cukanovaite, K. Burdge +3
We computed Doppler beaming factors for DA, DB, and DBA white dwarf models, as well as for main sequence and giant stars covering the transmission curves of the Sloan, UBVRI, HiPER…
white dwarfs within 40 pc I: spectroscopic observations of new candidates
P. -E. Tremblay, M. A. Hollands, N. P. Gentile Fusillo +30
We present a spectroscopic survey of 230 white dwarf candidates within 40 pc of the Sun from the William Herschel Telescope and Gran Telescopio Canarias. All candidates were select…
