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…
Rapidly Rising Transients in the Supernova - Superluminous Supernova Gap
Iair Arcavi, William M. Wolf, D. Andrew Howell +26
We present observations of four rapidly rising (t_{rise}~10d) transients with peak luminosities between those of supernovae (SNe) and superluminous SNe (M_{peak}~-20) - one discove…
Elliptical accretion and inefficient highly eccentric accretion and the low luminosity of stellar tidal disruption events
Gilad Svirski, Tsvi Piran, Julian Krolik
Models for tidal disruption events (TDEs) in which a supermassive black hole disrupts a star commonly assume that the highly eccentric streams of bound stellar debris promptly form…
"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…
SN 2008D: A Wolf-Rayet explosion through a thick wind
Gilad Svirski, Ehud Nakar
Supernova (SN) 2008D/XRT 080109 is considered to be the only direct detection of a shock breakout from a regular SN to date. While a breakout interpretation was favored by several…
Spectrum and light curve of a supernova shock breakout through a thick Wolf-Rayet wind
Gilad Svirski, Ehud Nakar
Wolf-Rayet stars are known to eject winds. Thus, when a Wolf-Rayet star explodes as a supernova, a fast, km/s, shock is expected to be driven through a wind. We study the…
