Unstable Mass Transfer from a Main-Sequence Star to a Supermassive Black Hole and Quasi-Periodic Eruptions
Itai Linial, Re'em Sari
We discuss the formation and evolution of systems comprised of a low-mass () main sequence star, orbiting a supermassi…
Shock Breakout from Stellar Envelopes: The relativistic limit
Tamar Faran, Re'em Sari
We calculate the observed luminosity and spectrum following the emergence of a relativistic shock wave from a stellar edges. Shock waves propagating at …
Stellar Distributions Around a Supermassive Black Hole: Strong Segregation Regime Revisited
Itai Linial, Re'em Sari
We present a new analytical solution to the steady-state distribution of stars close to a central supermassive black hole of mass in the center of a galaxy. Assuming…
Extreme Mass-Ratio Binary Black Hole Merger: Characteristics of the Test-Particle Limit
Barak Rom, Re'em Sari
We study binary black hole mergers in the extreme mass-ratio limit. We determine the energy, angular momentum, and linear momentum of the post-merger, remnant black hole. Unlike pr…
The Formation of Intermediate Mass Black Holes in Galactic Nuclei
Sanaea C. Rose, Smadar Naoz, Re'em Sari +1
Most stellar evolution models predict that black holes (BHs) should not exist above approximately M, the lower limit of the pair-instability mass gap. However, rece…
