Aspherical Remnants of Triple and Quadruple Detonations in Binary White Dwarfs
Logan J. Prust, Lars Bildsten, Samuel J. Boos
White dwarfs which explode by the double-detonation mechanism may have a binary white dwarf donor which is subsequently ignited by its collision with the ejecta. This results in th…
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 (,…
The First Day of a Type Ia Supernova from a Double-Degenerate Binary
Gabriel Kumar, Logan J. Prust, Lars Bildsten
Supernovae in binary star systems involve a hydrodynamical interaction between the ejecta and a binary companion. This collision results in shock heating and a modified density str…
Wakes from Companion Interactions in Type Ia Supernovae Nebular Emission Line Profiles
Kathlynn Simotas, Lars Bildsten, Logan J. Prust
Thermonuclear supernovae (SNe) are the result of the nuclear transformation of carbon/oxygen (C/O) white dwarfs (WDs) to the radioactive element and intermediate…
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…
Ejecta Wakes from Companion Interaction in Type Ia Supernova Remnants
Logan J. Prust, Gabriel Kumar, Lars Bildsten
Type Ia supernovae are triggered by accretion onto a white dwarf from a companion which is most likely Roche lobe-filling at the time of the explosion. The collision between the ej…
Morphology and Mach Number Dependence of Subsonic Bondi-Hoyle Accretion
Logan J. Prust, Hila Glanz, Lars Bildsten +2
We carry out three-dimensional computations of the accretion rate onto an object (of size and mass ) as it moves through a uniform medium at a subsonic speed $v_{…
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…
Rapidly Rising Transients in the Supernova - Superluminous Supernova Gap
Iair Arcavi, William M. Wolf, D. Andrew Howell +26
We present observations of four rapidly rising (t_{rise}~10d) transients with peak luminosities between those of supernovae (SNe) and superluminous SNe (M_{peak}~-20) - one discove…
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…
An outburst from a massive star 40 days before a supernova explosion
E. O. Ofek, M. Sullivan, S. B. Cenko +17
Various lines of evidence suggest that very massive stars experience extreme mass-loss episodes shortly before they explode as a supernova. Interestingly, several models predict su…
The Palomar Transient Factory photometric catalog 1.0
E. O. Ofek, R. Laher, J. Surace +22
We construct a photometrically calibrated catalog of non-variable sources from the Palomar Transient Factory (PTF) observations. The first version of this catalog presented here, t…
