Spectroscopic and kinematic analyses of a warm survivor of a D6 supernova
Mark A. Hollands, Ken. J. Shen, Roberto Raddi +3
SDSSJ163712.21+363155.9 is a candidate hyper-runaway star, first identified from its unusual spectrum in the Sloan Digital Sky Survey, which exhibits oxygen, magnesium, and silicon…
The dearth of high-mass hydrogen-atmosphere metal-polluted white dwarfs within 40 pc
Tim Cunningham, Pier-Emmanuel Tremblay, Mairi O'Brien +7
We present a population synthesis model which addresses the different mass distributions of the metal-polluted and non-metal-polluted hydrogen-atmosphere white dwarfs identified in…
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…
Evolution of binaries containing a hot subdwarf and a white dwarf to double white dwarfs, and double detonation supernovae with hypervelocity runaway stars
Abinaya Swaruba Rajamuthukumar, Evan B. Bauer, Stephen Justham +3
Compact binaries containing hot subdwarfs and white dwarfs have the potential to evolve into a variety of explosive transients. These systems could also explain hypervelocity runaw…
