The evolutionary history of ultra-compact accreting binaries. I. Chemical abundances and formation channel of the eclipsing AM CVn system ZTF J225237.05-051917.4 from HST spectroscopy
W. Yu, A. F. Pala, T. Kupfer +33
AM Canum Venaticorum (AM CVn) stars are ultra-compact binary systems composed of a white dwarf (WD) primary accreting from a H-deficient donor. They are important as potential prog…
A Catalogue of Ultracompact Mass-Transferring White Dwarf Binaries
Matthew J. Green, Jan van Roestel, Tin Long Sunny Wong
We present an overview and catalogue of all known mass-transferring binary systems that have white dwarf accretors and orbital periods shorter than 70 minutes, including the AM CVn…
A ZTF Search for Circumstellar Debris Transits in White Dwarfs: Six New Candidates, one with Gas Disk Emission, identified in a Novel Metric Space
Soumyadeep Bhattacharjee, Zachary P. Vanderbosch, Mark A. Hollands +13
White dwarfs (WDs) showing transits from orbiting planetary debris provide significant insights into the structure and dynamics of debris disks. This is a rare class of objects wit…
A rotating white dwarf shows different compositions on its opposite faces
Ilaria Caiazzo, Kevin B. Burdge, Pier-Emmanuel Tremblay +35
White dwarfs, the extremely dense remnants left behind by most stars after their death, are characterised by a mass comparable to that of the Sun compressed into the size of an Ear…
ZTF20aajnksq (AT2020blt): A Fast Optical Transient at With No Detected Gamma-Ray Burst Counterpart
Anna Y. Q. Ho, Daniel A. Perley, Paz Beniamini +27
We present ZTF20aajnksq (AT2020blt), a fast-fading ( mag in days) red ( mag) and luminous () optical transient at discovered…
Discovery of 36 eclipsing EL CVn binaries found by the Palomar Transient Factory
J. van Roestel, T. Kupfer, R. Ruiz-Carmona +6
We report the discovery and analysis of 36 new eclipsing EL CVn-type binaries, consisting of a core helium-composition pre-white dwarf and an early-type main-sequence companion, mo…
