Hubble as a Unique Discovery Engine of the Fate of Massive Stars and Black Hole Formation
Avishai Gilkis, Eva Laplace, Charles D. Kilpatrick +3
How stellar-mass black holes are formed is an open question in astrophysics, with very limited observational constraints. It is not known which types of stars are more likely to pr…
Mass-Orbital Period Distribution of Massive White Dwarfs Formed Through Stable Mass Transfer
Rizhong Zheng, Hongwei Ge, Christopher A Tout +10
White dwarfs (WDs) in binaries can form through either the stable mass-transfer process or common envelope evolution (CEE). Compared to CEE, the stable mass-transfer process can le…
Hydrogen-deficient binary stars with magnetic braking
David A. Bour, Avishai Gilkis, Christopher A. Tout
Hydrogen-deficient binary stars comprise one star which has been stripped of its hydrogen through mass transfer to a binary companion. Observations show that the companion is able…
Simulating super-Chandrasekhar white dwarfs
Zenia Zuraiq, Achal Kumar, Alexander J. Hackett +3
Over the last few decades, there has been considerable interest in the violation of the sacred "Chandrasekhar" mass limit of white dwarfs (WDs). Peculiar over-luminous type Ia supe…
