Fragmentation in Collapsar Disks: Migration, Growth, and Emission
Y. Lerner, N. C. Stone, D. D. Ofengeim
We present a parameter survey of fragmentation in collapsar disks, using a revised version of the Chen & Beloborodov (2007) model that determines the structure of steady state hype…
Wind-mediated Eddington-limited emission in a Black Hole Tidal Disruption Event
Paola Martire, Elena Maria Rossi, Nicholas Chamberlain Stone +3
Observations of tidal disruption events (TDEs) have already produced tens of strong candidate flares, and their number will greatly increase with upcoming wide field surveys. Never…
Late-Time Evolution of Magnetized Disks in Tidal Disruption Events
Yael Alush, Nicholas C. Stone
In classic time-dependent 1D accretion disk models, the inner radiation pressure dominated regime is viscously unstable. However, late-time observations of accretion disks formed i…
The unreasonable effectiveness of the approximation
Elisha Modelevsky, Nicholas C. Stone, Re'em Sari
In kinetic theory, the classic approach calculates the rate of particle interactions from local quantities: the number density of particles , the cross-section , and…
Disruptions of stars and binary systems on chaotic orbits in an axisymmetric Milky Way center
Zephyr Penoyre, Elena Maria Rossi, Nicholas C. Stone
Non-spherical potentials allow a wide range of trajectories, both regular and chaotic, whose periapse distances can vary orbit to orbit. In particular chaotic trajectories can brin…
Counting the Unseen II: Tidal Disruption Event Rates in Nearby Galaxies with REPTiDE
Christian H. Hannah, Nicholas C. Stone, Anil C. Seth +1
Tidal disruption events (TDEs) are a class of transients that occur when a star is destroyed by the tides of a massive black hole (MBH). Their rates encode valuable MBH demographic…
