The DESI Data Release 1 white dwarf catalogue
Andrew Swan, Boris T. Gänsicke, Paula Izquierdo +49
The Dark Energy Spectroscopic Instrument is conducting a redshift survey, mapping the universe in three dimensions to measure the history of cosmic expansion. As well as extragalac…
1000 cataclysmic variables identified from DESI spectroscopy
K. Inight, B. T. Gänsicke, A. Aungwerojwit +41
Most cataclysmic variables (CVs) are discovered when they have an outburst generating an inherent selection bias against CVs that rarely, or never, outburst. CVs discovered by virt…
The DESI Early Data Release White Dwarf Catalogue
Christopher J. Manser, Paula Izquierdo, Boris T. Gänsicke +51
The Early Data Release (EDR) of the Dark Energy Spectroscopic Instrument (DESI) comprises spectroscopy obtained from 2020 December 14 to 2021 June 10. White dwarfs were targeted by…
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…
White dwarfs with planetary remnants in the era of Gaia I: six emission line systems
N. P. Gentile Fusillo, C. J. Manser, Boris T. Gänsicke +17
White dwarfs with emission lines from gaseous debris discs are among the rarest examples of planetary remnant hosts, but at the same time they are key objects for studying the fina…
white dwarfs within 40 pc II: the volume-limited northern hemisphere sample
Jack McCleery, Pier-Emmanuel Tremblay, Nicola Pietro Gentile Fusillo +6
We present an overview of the sample of northern hemisphere white dwarfs within 40 pc of the Sun detected from Data Release 2 (DR2). We find that 521 sources are spectroscop…
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…
Spectroscopic and Photometric Periods of Six Ultracompact Accreting Binaries
Matthew J. Green, Thomas R. Marsh, Philip J. Carter +19
Ultracompact accreting binary systems each consist of a stellar remnant accreting helium-enriched material from a compact donor star. Such binaries include two related sub-classes,…
An ultra-massive white dwarf with a mixed hydrogen-carbon atmosphere as a likely merger remnant
Mark A. Hollands, Pier-Emmanuel Tremblay, Boris T. Gänsicke +11
White dwarfs are dense, cooling stellar embers consisting mostly of carbon and oxygen, or oxygen and neon (with a few percent carbon) at higher initial stellar masses. These stella…
When the disc's away, the stars will play: dynamical masses in the nova-like variable KR Aur with a pinch of accretion
P. Rodríguez-Gil, T. Shahbaz, M. A. P. Torres +8
We obtained time-resolved optical photometry and spectroscopy of the nova-like variable KR Aurigae in the low state. The spectrum reveals a DAB white dwarf and a mid-M dwarf compan…
A White Dwarf with Transiting Circumstellar Material Far Outside the Roche Limit
Z. Vanderbosch, J. J. Hermes, E. Dennihy +9
We report the discovery of a white dwarf exhibiting deep, irregularly shaped transits, indicative of circumstellar planetary debris. Using Zwicky Transient Facility DR2 photometry…
Fast spectrophotometry of WD 1145+017
P. Izquierdo, P. Rodríguez-Gil, B. T. Gänsicke +16
WD 1145+017 is currently the only white dwarf known to exhibit periodic transits of planetary debris as well as absorption lines from circumstellar gas. We present the first simult…
