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…

Spectroscopic Monitoring of Metal Lines in Polluted White Dwarfs

Laura K. Rogers, Michael M. Shara, Amy Bonsor +12

The disruption and accretion of planetary material onto white dwarfs is expected to be inherently dynamic and stochastic, potentially driving variability in the accretion rate and…

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…

The Morphology of Asteroidal Dust Around White Dwarf Stars: Optical and Near-infrared Pulsations in G29-38

T. von Hippel, J. Farihi, J. L. Provencal +20

More than 36 years have passed since the discovery of the infrared excess from circumstellar dust orbiting the white dwarf G29-38, which at 17.5 pc it is the nearest and brightest…

An emerging and enigmatic spectral class of isolated DAe white dwarfs

Abbigail K. Elms, Pier-Emmanuel Tremblay, Boris T. Gänsicke +9

Two recently discovered white dwarfs, WDJ041246.84754942.26 and WDJ165335.21100116.33, exhibit H and H Balmer line emission similar to stars in the emerging DAHe class,…

The SNIa Runaway LP 398-9: Detection of Circumstellar Material and Surface Rotation

Vedant Chandra, Hsiang-Chih Hwang, Nadia L. Zakamska +12

A promising progenitor scenario for Type Ia supernovae (SNeIa) is the thermonuclear detonation of a white dwarf in a close binary system with another white dwarf. After the primary…

8.9-hr Rotation in the Partly Burnt Runaway Stellar Remnant LP 40-365 (GD 492)

J. J. Hermes, Odelia Putterman, Mark A. Hollands +5

We report the detection of 8.914-hr variability in both optical and ultraviolet light curves of LP 40-365 (also known as GD 492), the prototype for a class of partly burnt runaway…

Carbon-enhanced stars with short orbital and spin periods

L. J. Whitehouse, J. Farihi, I. D. Howarth +5

Many characteristics of dwarf carbon stars are broadly consistent with a binary origin, including mass transfer from an evolved companion. While the population overall appears to h…

The dust never settles: collisional production of gas and dust in evolved planetary systems

Andrew Swan, Jay Farihi, Thomas G. Wilson +1

Multi-epoch infrared photometry from Spitzer is used to monitor circumstellar discs at white dwarfs, which are consistent with disrupted minor planets whose debris is accreted and…

Emission from elliptical streams of dusty debris around white dwarfs

C. J. Nixon, J. E. Pringle, E. R. Coughlin +2

White dwarfs are routinely observed to have polluted atmospheres, and sometimes significant infrared excesses, that indicate ongoing accretion of circumstellar dust and rocky debri…

Most white dwarfs with detectable dust discs show infrared variability

Andrew Swan, Jay Farihi, Thomas G. Wilson

Archival data from the WISE satellite reveals infrared flux variations of tens of per cent around numerous dusty white dwarfs. Data spanning more than seven years reveal more than…
