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…
Mass Loss and Subsequent Thermal Evolution of Surviving Helium White Dwarfs Shocked by Thermonuclear Supernovae
Tin Long Sunny Wong, Lars Bildsten
Following a type Ia supernova (SN Ia) in a double white dwarf (WD) binary, a surviving WD companion leaves at its orbital velocity ,000 - 3,000 km/s. The Gaia mission ha…
When Stars Mimic Monsters: Spectral Evidence for an Carinae-like Giant Eruption in SBS 0335052 E
Zixuan Peng, Crystal L. Martin, Jiamu Huang +7
SBS 0335052 E is an extremely low-metallicity () blue compact dwarf galaxy. An active galactic nucleus has been proposed to explain the broad H emission…
Accretion from a Shock-Inflated Companion: Spinning Down Neutron Stars to Hour-Long Periods
Savannah Cary, Wenbin Lu, Calvin Leung +1
Recent observations have unveiled a population of pulsars with spin periods of a few minutes to hours that lie beyond the traditional ``death line.'' If they originate from neutron…
Carbon burning cannot explain puffy hypervelocity white dwarfs
Natsuko Yamaguchi, Kareem El-Badry, Tin Long Sunny Wong +1
Several hypervelocity white dwarfs (HVWDs) with space velocities of have recently been discovered. One possible origin of these stars is the dynam…
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…
