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…
Relentless and Complex Transits from a Planetesimal Debris Disk
J. Farihi, J. J. Hermes, T. R. Marsh +11
This article reports quasi-continuous transiting events towards WD 1054-226 at d=36.2 pc and V=16.0 mag, based on simultaneous, high-cadence, multi-wavelength imaging photometry us…
Collisions in a gas-rich white dwarf planetary debris disc
Andrew Swan, Scott J. Kenyon, Jay Farihi +5
WD 0145+234 is a white dwarf that is accreting metals from a circumstellar disc of planetary material. It has exhibited a substantial and sustained increase in 3-5 micron flux sinc…
A CHEOPS White Dwarf Transit Search
Brett M. Morris, Kevin Heng, Alexis Brandeker +2
White dwarf spectroscopy shows that nearly half of white dwarf atmospheres contain metals that must have been accreted from planetary material that survived the red giant phases of…
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…
