He-star donor pathway for the hypervelocity star D6-2
Abinaya Swaruba Rajamuthukumar, Ruediger Pakmor, Stephen Justham +2
Type Ia supernovae are thermonuclear explosions of white dwarfs, yet the nature of their progenitor systems remains uncertain. Recent discoveries of hypervelocity stars provide uni…
Violent mergers can explain the inflated state of some of the fastest stars in the Galaxy
Aakash Bhat, Rüdiger Pakmor, Ken J. Shen +2
A significant number of hypervelocity stars with velocities between km/s have recently been observed. The only plausible explanation so far is that they have been produ…
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…
A super-Chandrasekhar mass type Ia supernova progenitor at 49 pc set to detonate in 23 Gyr
James Munday, Ruediger Pakmor, Ingrid Pelisoli +9
Double white dwarf binaries are a leading explanation to the origin of type Ia supernovae, but no system exceeding the Chandrasekhar mass limit (1.4 M) has been found that…
Prompt stellar and binary black hole mergers in tight triples: Insights from chemically homogeneous evolution
Alejandro Vigna-Gómez, Evgeni Grishin, Jakob Stegmann +7
Short-period massive binary stars are predicted to undergo chemically homogeneous evolution (CHE), making them prime candidates for producing binary black holes (BBHs) that may mer…
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…
