Spoon-Feeding Giant Stars to Supermassive Black Holes: Episodic Mass Transfer from Evolving Stars and Their Contribution to the Quiescent Activity of Galactic Nuclei
Morgan MacLeod, Enrico Ramirez-Ruiz, Sean Grady +1
Stars may be tidally disrupted if, in a single orbit, they are scattered too close to a supermassive black hole (SMBH). Tidal disruption events are thought to power luminous but sh…
Turbovelocity Stars: Kicks Resulting From the Tidal Disruption of Solitary Stars
Haik Manukian, James Guillochon, Enrico Ramirez-Ruiz +1
The centers of most known galaxies host supermassive black holes (SMBHs). In orbit around these black holes are a centrally-concentrated distribution of stars, both in single and i…
PS1-10jh: The Disruption of a Main-Sequence Star of Near-Solar Composition
James Guillochon, Haik Manukian, Enrico Ramirez-Ruiz
When a star comes within a critical distance to a supermassive black hole (SMBH), immense tidal forces disrupt the star, resulting in a stream of debris that falls back onto the SM…
Conditions For Successful Helium Detonations In Astrophysical Environments
Cole Holcomb, James Guillochon, Fabio De Colle +1
Several models for type Ia-like supernovae events rely on the production of a self-sustained detonation powered by nuclear reactions. In the absence of hydrogen, the fuel that powe…
Circumstellar absorption in double detonation Type Ia supernovae
Ken J. Shen, James Guillochon, Ryan J. Foley
Upon formation, degenerate He core white dwarfs are surrounded by a radiative H-rich layer primarily supported by ideal gas pressure. In this Letter, we examine the effect of this…
