A Faint Progenitor System for the Faint Supernova 2024vjm
Erez A. Zimmerman, Avishay Gal-Yam, Paul J. Groot +68
Type Ia Supernovae (SNe Ia) are well known for their role as standardizable cosmological candles. Their uniformity is credited to their single origin as thermonuclear explosions of…

Super-Eddington accretion onto black holes and its application to fallback accretion
Tamar Faran, Eliot Quataert
We study the problem of steady-state spherical accretion onto a black hole, in which the internal energy of the flow is governed by radiation and photon diffusion dominates the ene…

Nonlinear perturbations and weak shock waves in isentropic atmospheres
Tamar Faran, Christopher D. Matzner, Eliot Quataert
Acoustic perturbations to stellar envelopes can lead to the formation of weak shock waves via nonlinear wave-steepening. Close to the stellar surface, the weak shock wave increases…
