Mass Loss and Subsequent Thermal Evolution of Surviving Helium White Dwarfs Shocked by Thermonuclear Supernovae
Tin Long Sunny Wong, Lars Bildsten
Following a type Ia supernova (SN Ia) in a double white dwarf (WD) binary, a surviving WD companion leaves at its orbital velocity ,000 - 3,000 km/s. The Gaia mission ha…
Type IIb Supernova Progenitors in 3D: Variability and Episodic Mass Loss revealed by Radiation-Hydrodynamics Simulations
Jared A. Goldberg, Yan-Fei Jiang, Lars Bildsten +1
We present the first 3D Radiation-Hydrodynamics simulations of partially-stripped (, ) Yellow Supergiant (,…
Stochastic low-frequency variability of 50 massive stars in the Cygnus OB associations and the Small Magellanic Cloud
M. G. Pedersen, L. Bildsten
In recent years, high-precision high-cadence space photometry has revealed that stochastic low frequency (SLF) variability is common in the light curves of massive stars. We use th…
Flow Morphology of a Supersonic Gravitating Sphere
Logan J. Prust, Lars Bildsten
Stars and planets move supersonically in a gaseous medium during planetary engulfment, stellar interactions and within protoplanetary disks. For a nearly uniform medium, the releva…
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…
Modules for Experiments in Stellar Astrophysics (MESA): Convective Boundaries, Element Diffusion, and Massive Star Explosions
Bill Paxton, Josiah Schwab, Evan B. Bauer +10
We update the capabilities of the software instrument Modules for Experiments in Stellar Astrophysics (MESA) and enhance its ease of use and availability. Our new approach to locat…
The diversity of Type II supernova versus the similarity in their progenitors
S. Valenti, D. A. Howell, M. D. Stritzinger +19
High-quality collections of Type II supernova (SN) light curves are scarce because they evolve for hundreds of days, making follow-up observations time consuming and often extendin…
Modules for Experiments in Stellar Astrophysics (MESA): Binaries, Pulsations, and Explosions
Bill Paxton, Pablo Marchant, Josiah Schwab +10
We substantially update the capabilities of the open-source software instrument Modules for Experiments in Stellar Astrophysics (MESA). MESA can now simultaneously evolve an intera…
An Accreting White Dwarf near the Chandrasekhar Limit in the Andromeda Galaxy
Sumin Tang, Lars Bildsten, William M. Wolf +13
The iPTF detection of the most recent outburst of the recurrent nova system RX J0045.4+4154 in the Andromeda Galaxy has enabled the unprecedented study of a massive ($M>1.3\ M_\odo…
Solar-like oscillations in low-luminosity red giants: first results from Kepler
T. R. Bedding, D. Huber, D. Stello +47
We have measured solar-like oscillations in red giants using time-series photometry from the first 34 days of science operations of the Kepler Mission. The light curves, obtained w…
