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…
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 half-ring of ionized circumstellar material trapped in the magnetosphere of a white dwarf merger remnant
Andrei A. Cristea, Ilaria Caiazzo, Tim Cunningham +31
Many white dwarfs are observed in compact double white dwarf binaries and, through the emission of gravitational waves, a large fraction are destined to merge. The merger remnants…
Follow-up on three poorly studied AM CVn stars
Amornrat Aungwerojwit, Boris T. Gaensicke, E. Breedt +12
We report follow-up observations of three poorly studied AM CVn-type binaries: CRTS CSS150211 J091017-200813, NSV1440, and SDSSJ183131.63+420220.2. Analysing time-series photometry…
TIC 378898110: A Bright, Short-Period AM CVn Binary in TESS
Matthew J. Green, J. J. Hermes, Brad N. Barlow +22
AM CVn-type systems are ultracompact, helium-accreting binary systems which are evolutionarily linked to the progenitors of thermonuclear supernovae and are expected to be strong G…
An HST COS ultra-violet spectroscopic survey of 311 DA white dwarfs.I. Fundamental parameters and comparative studies
Snehalata Sahu, Boris T. Gaensicke, Pier-Emmanuel Tremblay +8
White dwarf studies carry significant implications across multiple fields of astrophysics, including exoplanets, supernova explosions, and cosmological investigations. Thus, accura…
