On the Survivability and Metamorphism of Tidally Disrupted Giant Planets: the Role of Dense Cores
Shang-Fei Liu, James Guillochon, Douglas N. C. Lin +1
A large population of planetary candidates in short-period orbits have been found through transit searches. Radial velocity surveys have also revealed several Jupiter-mass planets…
Electromagnetic transients as triggers in searches for gravitational waves from compact binary mergers
Luke Zoltan Kelley, Ilya Mandel, Enrico Ramirez-Ruiz
The detection of an electromagnetic transient which may originate from a binary neutron star merger can increase the probability that a given segment of data from the LIGO-Virgo gr…
The Tidal Disruption of Giant Stars and Their Contribution to the Flaring Supermassive Black Hole Population
Morgan MacLeod, James Guillochon, Enrico Ramirez-Ruiz
Sun-like stars are thought to be regularly disrupted by supermassive black holes (SMBHs) within galactic nuclei. Yet, as stars evolve off the main sequence their vulnerability to t…
Hydrodynamical Simulations to Determine the Feeding Rate of Black Holes by the Tidal Disruption of Stars: The Importance of the Impact Parameter and Stellar Structure
James Guillochon, Enrico Ramirez-Ruiz
The disruption of stars by supermassive black holes has been linked to more than a dozen flares in the cores of galaxies out to redshift . Modeling these flares properl…
The dynamics, appearance and demographics of relativistic jets triggered by tidal disruption of stars in quiescent supermassive black holes
Fabio De Colle, James Guillochon, Jill Naiman +1
We examine the consequences of a model in which relativistic jets can be triggered in quiescent massive black holes when a geometrically thick and hot accretion disk forms as a res…
No snow-plough mechanism during the rapid hardening of supermassive black hole binaries
Clément Baruteau, Enrico Ramirez-Ruiz, Frédéric Masset
We present two-dimensional hydrodynamical simulations of the tidal interaction between a supermassive black hole binary with moderate mass ratio, and the fossil gas disc where it i…
