Multiple outflows and delayed ejections revealed by early imaging of novae

Elias Aydi, John D. Monnier, Antoine Mérand +39

Novae are thermonuclear eruptions on accreting white dwarfs in interacting binaries. Although most of the accreted envelope is expelled, the mechanism -- impulsive ejection, multip…

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…

Carbon burning cannot explain puffy hypervelocity white dwarfs

Natsuko Yamaguchi, Kareem El-Badry, Tin Long Sunny Wong +1

Several hypervelocity white dwarfs (HVWDs) with space velocities of have recently been discovered. One possible origin of these stars is the dynam…

Spectroscopic and kinematic analyses of a warm survivor of a D6 supernova

Mark A. Hollands, Ken. J. Shen, Roberto Raddi +3

SDSSJ163712.21+363155.9 is a candidate hyper-runaway star, first identified from its unusual spectrum in the Sloan Digital Sky Survey, which exhibits oxygen, magnesium, and silicon…

The Evolution of Hypervelocity Supernova Survivors and the Outcomes of Interacting Double White Dwarf Binaries

Ken J. Shen

The recent prediction and discovery of hypervelocity supernova survivors has provided strong evidence that the "dynamically driven double-degenerate double-detonation" (D6) Type Ia…
