Simulations of Interacting Binary Systems -- Pathways to Radio Bright GRB Progenitors
Angel Hernandez, Roseanne M. Cheng, Nicole M. Lloyd-Ronning +1
Although the association of gamma-ray bursts with massive stellar death is on firm footing, the nature of the progenitor system and the key ingredients required for a massive star…
Understanding Binary Systems -- a Comparison between COSMIC and MESA
Lailani Kenoly, A. Ken Luu, Celia Toral +4
We compare the evolution of binary systems evolved in the MESA stellar evolution code to those in the COSMIC population synthesis code. Our aim is to convey the robustness of the e…
On the Anti-Correlation between Duration and Redshift in Gamma-ray Bursts
Nicole M. Lloyd-Ronning, Jarrett L. Johnson, Roseanne M. Cheng +4
For gamma-ray bursts (GRBs) with durations greater than two seconds (so-called long GRBs), the intrinsic prompt gamma-ray emission appears, on average, to last longer for bursts at…
The Physics of Accretion Discs, Winds And Jets in Tidal Disruption Events
Jane Lixin Dai, Giuseppe Lodato, Roseanne M. Cheng
Accretion onto black holes is an efficient mechanism in converting the gas mass-energy into energetic outputs as radiation, wind and jet. Tidal disruption events, in which stars ar…
Simulations of Tidal Disruption Events
Giuseppe Lodato, Roseanne M. Cheng, Clement Bonnerot +1
Numerical simulations have historically played a major role in understanding the hydrodynamics of the tidal disruption process. Given the complexity of the geometry of the system,…
Stellar Tidal Disruption Events in General Relativity
Nicholas C. Stone, Michael Kesden, Roseanne M. Cheng +1
A tidal disruption event (TDE) ensues when a star passes too close to the supermassive black hole (SMBH) in a galactic center and is ripped apart by the tidal field of the SMBH. Th…
ASASSN-14li: A Model Tidal Disruption Event
Julian Krolik, Tsvi Piran, Gilad Svirski +1
ASASSN-14li is a recently-discovered tidal disruption event with an exceptionally rich data-set: spectra and lightcurves in soft X-rays, UV, optical, and radio. To understand its e…
"Circularization" vs. Accretion -- What Powers Tidal Disruption Events?
Tsvi Piran, Gilad Svirski, Julian Krolik +2
A tidal disruption event (TDE) takes place when a star passes near enough to a massive black hole to be disrupted. About half the star's matter is given elliptical trajectories wit…
General Relativistic Hydrodynamic Simulation of Accretion Flow from a Stellar Tidal Disruption
Hotaka Shiokawa, Julian H. Krolik, Roseanne M. Cheng +2
We study how the matter dispersed when a supermassive black hole tidally disrupts a star joins an accretion flow. Combining a relativistic hydrodynamic simulation of the stellar di…
Disruption of a Red Giant Star by a Supermassive Black Hole and the Case of PS1-10jh
Tamara Bogdanovic, Roseanne M. Cheng, Pau Amaro-Seoane
The development of a new generation of theoretical models for tidal disruptions is timely, as increasingly diverse events are being captured in surveys of the transient sky. Recent…
