Modules for experiments in stellar astrophysics (mesa): binaries, pulsations, and explosions
Bill Paxton,Pablo Marchant,Josiah Schwab,Evan B. Bauer,Lars Bildsten,Lars Bildsten,Matteo Cantiello,Luc Dessart,Robert Farmer,Haili Hu,Norbert Langer,Richard H. D. Townsend,Dean M. Townsley,Francis Timmes +13 more
TL;DR: Modules for Experiments in Stellar Astrophysics (MESA) as discussed by the authors can now simultaneously evolve an interacting pair of differentially rotating stars undergoing transfer and loss of mass and angular momentum, greatly enhancing the prior ability to model binary evolution.

TL;DR: In this article, a search for hypervelocity runaway double white dwarf (WD) binaries undergoing unstable mass transfer has been performed using Gaia's second data release, followed up with ground-based instruments.
Journal ArticleDOI
Sub-Chandrasekhar-mass white dwarf detonations revisited
TL;DR: In this article, the authors revisited simulations of naked C/O WD detonations and found that a median-brightness SN Ia is produced by the detonation of a 1.0 Msol WD instead of a more massive and rarer 1.1Msol WD.
Journal ArticleDOI
Theoretical Modeling of the Thermal State of Accreting White Dwarfs Undergoing Classical Nova Cycles
Dean M. Townsley,Lars Bildsten +1 more
TL;DR: In this paper, the impact of the accumulating envelope on the thermal state of the underlying WD has been investigated and the core temperatures, the ignition masses, and the thermal luminosities for WDs accreting at rates of 10-11 to 10-8 MΩ yr-1 were derived.
