A gravitational wave detectable candidate Type Ia supernova progenitor
Emma T. Chickles, Kevin B. Burdge, Joheen Chakraborty +37
Type Ia supernovae, critical for studying cosmic expansion, arise from thermonuclear explosions of white dwarfs, but their precise progenitor pathways remain unclear. Growing evide…
Expanding the ultracompacts: gravitational wave-driven mass transfer in the shortest-period binaries with accretion disks
Joheen Chakraborty, Kevin B. Burdge, Saul A. Rappaport +35
We report the discovery of three ultracompact binary white dwarf systems hosting accretion disks, with orbital periods of 7.95, 8.68, and 13.15 minutes. This significantly augments…
Analysis of optical spectroscopy and photometry of the type I X-ray bursting system UW CrB
M. R. Kennedy, P. Callanan, P. M. Garnavich +19
UW Coronae Borealis (UW CrB) is a low mass X-ray binary that shows both Type 1 X-ray and optical bursts, which typically last for 20 s. The system has a binary period of close to 2…
The white dwarf binary pathways survey -- X. Gaia orbits for known UV excess binaries
J. A. Garbutt, S. G. Parsons, O. Toloza +9
White dwarfs with a F, G or K type companion represent the last common ancestor for a plethora of exotic systems throughout the galaxy, though to this point very few of them have b…
A Survey for Radio Emission from White Dwarfs in the VLA Sky Survey
Ingrid Pelisoli, Laura Chomiuk, Jay Strader +22
Radio emission has been detected from tens of white dwarfs, in particular in accreting systems. Additionally, radio emission has been predicted as a possible outcome of a planetary…
Formation of long-period post-common-envelope binaries I. No extra energy is needed to explain oxygen-neon white dwarfs paired with AFGK-type main-sequence stars
Diogo Belloni, Monica Zorotovic, Matthias R. Schreiber +3
In this first in a series of papers related to long-period post-common-envelope (CE) binaries, we investigated whether extra energy is required or not to explain the currently know…
