The white dwarf population of open clusters and their tidal tails. Tracers of contamination and stellar interactions
Vikrant V. Jadhav, Pavel Kroupa, David R. Miller +3
Recent Gaia studies have identified numerous open clusters (OCs) & tidal tail catalogues, enabling systematic searches for white dwarfs (WDs) associated with clusters & their exten…
White dwarfs within 13 pc: insights from ultraviolet spectroscopy
Mairi W. O'Brien, Pier-Emmanuel Tremblay, Boris T. Gänsicke +10
We present a comprehensive multi-wavelength spectroscopic and photometric analysis of the 44 confirmed white dwarfs within 13 pc of the Sun. Combining flux-calibrated ultraviolet s…
Re-evaluating Lyman wing opacities and the low mass-problem in cool white dwarfs
Snehalata Sahu, Pier-Emmanuel Tremblay, Detlev Koester +4
Gaia observations have reignited interest in the optical and ultraviolet (UV) opacity problems of cool white dwarfs ( K), which were thought to be resolved n…
Precise Parameters for Two LISA Sources
Manuel Barrientos, Mukremin Kilic, Warren R. Brown +5
We present precise parameters for two compact double white dwarf binaries, SDSS J232230.20+050942.0 (J2322+0509) and SDSS J063449.92+380352.2 (J0634+3803), with orbital periods of…
A hot white dwarf merger remnant revealed by an ultraviolet detection of carbon
Snehalata Sahu, Antoine Bédard, Boris T. Gänsicke +7
Atmospheric carbon has been detected in the optical spectra of six hydrogen-rich ultra-massive white dwarfs, revealing large carbon abundances (log C/H > 0.5) attributable to th…
A super-Chandrasekhar mass type Ia supernova progenitor at 49 pc set to detonate in 23 Gyr
James Munday, Ruediger Pakmor, Ingrid Pelisoli +9
Double white dwarf binaries are a leading explanation to the origin of type Ia supernovae, but no system exceeding the Chandrasekhar mass limit (1.4 M) has been found that…
A network of cooler white dwarfs as infrared standards for flux calibration
Abbigail K. Elms, Nicola Pietro Gentile Fusillo, Pier-Emmanuel Tremblay +6
The accurate flux calibration of observational data is vital for astrophysics and cosmology because absolute flux uncertainties of stellar standards propagate into scientific resul…
Ultraviolet extinction correlation with 3D dust maps using white dwarfs
Snehalata Sahu, Pier-Emmanuel Tremblay, Rosine Lallement +2
Accurate astrometric and photometric measurements from Gaia have led to the construction of 3D dust extinction maps which can now be used for estimating the integrated extinctions…
Constraints on Remnant Planetary Systems as a Function of Main-Sequence Mass with HST/COS
Lou Baya Ould Rouis, J. J. Hermes, Boris T. Gänsicke +8
As the descendants of stars with masses less than 8 M on the main sequence, white dwarfs provide a unique way to constrain planetary occurrence around intermediate-mass s…
The Gaia white dwarf revolution
Pier-Emmanuel Tremblay, Antoine Bédard, Mairi W. O'Brien +4
This review highlights the role of the Gaia space mission in transforming white dwarf research. These stellar remnants constitute 5-7% of the local stellar population in volume, ye…
