You're Gonna Need a Bigger Core: Calibrating Massive Star Models against Galactic OB-type Stars
Thibault Lechien, Selma E. de Mink, Stephen Justham +3
The evolution of massive stars above 8 M depends critically on the amount of mixing above the convective core during the main sequence. However, current models typically ex…
Thermal-timescale accretion does not always yield critical rotation in mass gainers
Chen Wang, Mike Y. M. Lau, Xiang-Dong Li +7
Binary evolution plays a central role in producing rapidly rotating stars. Previous studies have shown that mass gainers in binaries can reach critical rotation after accreting onl…
Violent mergers revisited: The origin of the fastest stars in the Galaxy
Rüdiger Pakmor, Ken J. Shen, Aakash Bhat +12
Binary systems of two carbon-oxygen white dwarfs are one of the most promising candidates for the progenitor systems of Type Ia supernovae. Violent mergers, where the primary white…
Dynamical binary interactions in the 2040s
Nadejda Blagorodnova, OndÅej Pejcha, Tomek KamiÅski +15
Dynamical binary interactions such as common envelope (CE) evolution or stellar mergers are a critical phase in the formation of a wide variety of binary phenomena, ranging from bl…
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…
The role of triple evolution in the formation of LISA double white dwarfs
Abinaya Swaruba Rajamuthukumar, Valeriya Korol, Jakob Stegmann +5
Galactic double white dwarfs will be prominent gravitational-wave sources for the Laser Interferometer Space Antenna (LISA). While previous studies have primarily focused on format…
