The OmegaWhite survey for short-period variable stars - V. Discovery of an ultracompact hot subdwarf binary with a compact companion in a 44 minute orbit
T. Kupfer, G. Ramsay, J. van Roestel +20
We report the discovery of the ultracompact hot subdwarf (sdOB) binary OW J074106.0-294811.0 with an orbital period of P min, making it the…
Fast and Luminous Transients from the Explosions of Long Lived Massive White Dwarf Merger Remnants
Jared Brooks, Josiah Schwab, Lars Bildsten +4
We study the evolution and final outcome of long-lived ( years) remnants from the merger of a He white dwarf (WD) with a more massive C/O or O/Ne WD. Using Modules f…
HD 49798: Its History of Binary Interaction and Future Evolution
Jared Brooks, Thomas Kupfer, Lars Bildsten
The bright subdwarf-O star (sdO), HD 49798, is in a 1.55 day orbit with a compact companion that is spinning at 13.2 seconds. Using the measurements of the effective temperature ($…
Accretion-Induced Collapse From Helium Star + White Dwarf Binaries
Jared Brooks, Josiah Schwab, Lars Bildsten +2
Accretion-induced collapse (AIC) occurs when an O/Ne white dwarf (WD) grows to nearly the Chandrasekhar mass (), reaching central densities that trigger electron captur…
Carbon Shell or Core Ignitions in White Dwarfs Accreting from Helium Stars
Jared Brooks, Lars Bildsten, Josiah Schwab +1
White dwarfs accreting from helium stars can stably burn at the accreted rate and avoid the challenge of mass loss associated with unstable Helium burning that is a concern for man…
AM Canum Venaticorum Progenitors with Helium Star Donors and the resultant Explosions
Jared Brooks, Lars Bildsten, Pablo Marchant +1
We explore the outcome of mass transfer via Roche lobe overflow (RLOF) of pure helium burning stars in close binaries with white dwarfs (WDs). The…
