J-PLUS: The fraction of calcium white dwarfs along the cooling sequence
C. López-Sanjuan, P. -E. Tremblay, M. W. O'Brien +24
We used the Javalambre Photometric Local Universe Survey (J-PLUS) DR2 photometry in twelve optical bands over 2176 deg2 to estimate the fraction of white dwarfs with presence of Ca…
The 40 pc sample of white dwarfs from Gaia
Mairi W. O'Brien, P. -E. Tremblay, B. L. Klein +14
We present a comprehensive overview of a volume-complete sample of white dwarfs located within 40 pc of the Sun, a significant proportion of which were detected in Gaia Data Releas…
Cataclysmic Variables from Sloan Digital Sky Survey V -- the search for period bouncers continues
K. Inight, Boris T. Gänsicke, A. Schwope +25
SDSS-V is carrying out a dedicated survey for white dwarfs, single and in binaries, and we report the analysis of the spectroscopy of cataclysmic variables (CVs) and CV candidates…
Systematic uncertainties in the characterisation of helium-dominated metal-polluted white dwarf atmospheres
Paula Izquierdo, Boris T. Gänsicke, Pablo Rodríguez-Gil +5
White dwarf photospheric parameters are usually obtained by means of spectroscopic or photometric analysis. These results are not always consistent with each other, with the publis…
Pulsating H-deficient WDs and pre-WDs observed with TESS: V. Discovery of two new DBV pulsators, WD J152738.4-450207.4 and WD 1708-871, and asteroseismology of the already known DBV stars PG 1351+489, EC 20058-5234, and EC 04207-4748
Alejandro H. Córsico, Murat Uzundag, S. O. Kepler +9
The {\sl TESS} space mission has recently demonstrated its great potential to discover new pulsating white dwarf and pre-white dwarf stars, and to detect periodicities with high pr…
Spectral analysis of ultra-cool white dwarfs polluted by planetary debris
Abbigail K. Elms, Pier-Emmanuel Tremblay, Boris T. Gänsicke +5
We identify two ultra-cool ( K) metal-polluted (DZ) white dwarfs WDJ21474035 and WDJ19220233 as the coolest and second coolest DZ stars known to date w…
Kinematic properties of white dwarfs. Galactic orbital parameters and age-velocity dispersion relation
R. Raddi, S. Torres, A. Rebassa-Mansergas +9
We present the first detailed 3D kinematic analysis of a sample of 3133 white dwarfs that use Gaia astrometry plus radial velocities, which were measured either by Gaia or by groun…
J-PLUS: Spectral evolution of white dwarfs by PDF analysis
C. López-Sanjuan, P. -E. Tremblay, A. Ederoclite +17
We estimated the spectral evolution of white dwarfs with effective temperature using the Javalambre Photometric Local Universe Survey (J-PLUS) second data release (DR2), that provi…
Can magnetic fields suppress convection in the atmosphere of cool white dwarfs? A case study on WD2105-820
Nicola Pietro Gentile Fusillo, Pier-Emmanuel Tremblay, Stefan Jordan +3
Around 10% of white dwarfs exhibit global magnetic structures with fields ranging from 1 kG to hundreds of MG. Recently, the first radiation magnetohydrodynamics simulations of the…
Using large spectroscopic surveys to test the double degenerate model for Type Ia supernovae
E. Breedt, D. Steeghs, T. R. Marsh +10
An observational constraint on the contribution of double degenerates to Type Ia supernovae requires multiple radial velocity measurements of ideally thousands of white dwarfs. Thi…
The population of hot subdwarf stars studied with Gaia I. The catalogue of known hot subdwarf stars
S. Geier, R. H. Østensen, P. Nemeth +5
In preparation for the upcoming all-sky data releases of the Gaia mission we compiled a catalogue of known hot subdwarf stars and candidates drawn from the literature and yet unpub…
The First Six Outbursting Cool DA White Dwarf Pulsators
Keaton J. Bell, J. J. Hermes, M. H. Montgomery +4
Extensive observations from the Kepler spacecraft have recently revealed a new outburst phenomenon operating in cool pulsating DA (hydrogen atmosphere) white dwarfs (DAVs). With th…
Outbursts in two new cool pulsating DA white dwarfs
Keaton J. Bell, J. J. Hermes, M. H. Montgomery +9
The unprecedented extent of coverage provided by Kepler observations recently revealed outbursts in two hydrogen-atmosphere pulsating white dwarfs (DAVs) that cause hours-long incr…
Analysis of cool DO-type white dwarfs from the Sloan Digital Sky Survey Data Release 10
N. Reindl, T. Rauch, K. Werner +3
We report on the identification of 22 new cool DO-type white dwarfs (WD) detected in Data Release 10 (DR10) of the Sloan Digital Sky Survey (SDSS). Among them, we found one more me…
