Parameterizing the Supernova Engine and its Effects on Remnants and Basic Yields
Chris L. Fryer, Sydney Andrews, Wesley Even +2
Core-collapse supernova science is now entering an era where engine models are beginning to make both qualitative and quantitative predictions. Although the evidence in support of…
Black hole hyperaccretion inflow-outflow model. I. long and ultra-long gamma-ray bursts
Tong Liu, Cui-Ying Song, Bing Zhang +2
Long-duration gamma-ray bursts (LGRBs) and ultra-LGRBs (ULGRBs) originate from collapsars, in the center of which a newborn rotating stellar-mass black hole (BH) surrounded by a ma…
Simulating X-ray bursts during a transient accretion event
Zac Johnston, Alexander Heger, Duncan K. Galloway
Modelling of thermonuclear X-ray bursts on accreting neutron stars has to date focused on stable accretion rates. However, bursts are also observed during episodes of transient acc…
High Resolution Study of Presupernova Compactness
Tuguldur Sukhbold, Stan Woosley, Alexander Heger
The density structure surrounding the iron core of a massive star when it dies is known to have a major effect on whether or not the star explodes. Here we repeat previous surveys…
Thermonuclear Bursts with Short Recurrence Times from Neutron Stars Explained by Opacity-Driven Convection
L. Keek, A. Heger
Thermonuclear flashes of hydrogen and helium accreted onto neutron stars produce the frequently observed Type I X-ray bursts. It is the current paradigm that almost all material bu…
