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…
