Simulations of Magnetic Fields in Tidally-Disrupted Stars
James Guillochon, Michael McCourt
We perform the first magnetohydrodynamical simulations of tidal disruptions of stars by supermassive black holes. We consider stars with both tangled and ordered magnetic fields, f…
Using gas clouds to probe the accretion flow around SgrA*: G2's delayed pericenter passage
Ann-Marie Madigan, Michael McCourt, Ryan O'Leary
We study the dynamical evolution of the putative gas clouds G1 and G2 recently discovered in the Galactic center. Following earlier studies suggesting that these two clouds are par…
Unbound Debris Streams and Remnants Resulting From the Tidal Disruptions of Stars by Supermassive Black Holes
James Guillochon, Michael McCourt, Xian Chen +2
The kinetic energy of a star in orbit about a supermassive black hole is a significant fraction of its rest mass energy when its periapse is comparable to its tidal radius. Upon it…
Going with the flow: using gas clouds to probe the accretion flow feeding Sgr A*
Michael McCourt, Ann-Marie Madigan
The massive black hole in our galactic center, Sgr A*, accretes only a small fraction of the gas available at its Bondi radius. The physical processes determining this accretion ra…
