On the Origin of Mass Ejection in Failed Supernovae
Daniel A. Paradiso, Sarah Vallejo, Eric R. Coughlin
Some high-mass stars likely end their lives in underluminous implosions that leave behind a black hole, known as failed supernovae (FSNe). However, neutrinos radiated during proto-…
Gotta Go Fast: A Generalization of the Escape Speed to Fluid-dynamical Explosions and Implications for Astrophysical Transients
Daniel A. Paradiso, Eric R. Coughlin
A star's ability to explode in a core-collapse supernova is correlated with its density profile, , such that compact stars with shallow density profiles preferentially ``fail…
The Peak of the Fallback Rate from Tidal Disruption Events: Dependence on Stellar Type
Ananya Bandopadhyay, Julia Fancher, Aluel Athian +7
A star completely destroyed in a tidal disruption event (TDE) ignites a luminous flare that is powered by the fallback of tidally stripped debris to a supermassive black hole (SMBH…
Low-energy Explosions in a Gravitational Field: Implications for Sub-energetic Supernovae and Fast X-ray Transients
Daniel A. Paradiso, Eric R. Coughlin, Jonathan Zrake +1
Observations and theory suggest that core-collapse supernovae can span a range of explosion energies, and when sub-energetic, the shockwave initiating the explosion can decelerate…
