Revealing the binary origin of Type Ic superluminous supernovae through nebular hydrogen emission
Takashi J. Moriya, Zheng-Wei Liu, Jonathan Mackey +2
We propose that nebular H-alpha emission as detected in the Type Ic superluminous supernova iPTF13ehe stems from matter which is stripped from a companion star when the supernova e…
On the nature of rapidly fading Type II supernovae
Takashi J. Moriya, Maria V. Pruzhinskaya, Mattias Ergon +1
It has been suggested that Type II supernovae with rapidly fading light curves (a.k.a. Type IIL supernovae) are explosions of progenitors with low-mass hydrogen-rich envelopes whic…
The interaction of core-collapse supernova ejecta with a companion star
Zheng-Wei Liu, Thomas M. Tauris, Friedrich K. Roepke +4
The progenitors of many CCSNe are expected to be in binary systems. After the SN explosion, the companion may suffer from mass stripping and be shock heated as a result of the impa…
Early ultraviolet signatures from the interaction of Type Ia supernova ejecta with a stellar companion
Zheng-Wei Liu, Takashi J. Moriya, Richard J. Stancliffe
The progenitors of SNe Ia are not yet fully understood. The two leading progenitor scenarios are the single-degenerate (SD) scenario and the double-degenerate scenario. In the SD s…
Envelope inflation in Wolf-Rayet stars and extended supernova shock breakout signals
Debashis Sanyal, Takashi J. Moriya, Norbert Langer
Massive, luminous stars reaching the Eddington limit in their interiors develop very dilute, extended envelopes. This effect is called envelope inflation. If the progenitors of Typ…
Type IIb Supernova 2013df Entering Into An Interaction Phase: A Link between the Progenitor and the Mass Loss
K. Maeda, T. Hattori, D. Milisavljevic +23
We report the late-time evolution of Type IIb Supernova (SN IIb) 2013df. SN 2013df showed a dramatic change in its spectral features at ~1 year after the explosion. Early on it sho…
Observable fractions of core-collapse supernova light curves brightened by binary companions
Takashi J. Moriya, Zheng-Wei Liu, Robert G. Izzard
Many core-collapse supernova progenitors are presumed to be in binary systems. If a star explodes in a binary system, the early supernova light curve can be brightened by the colli…
SN 2009ip: Constraining the latest explosion properties by its late-phase light curve
Takashi J. Moriya
We constrain the explosion and circumstellar properties at the 2012b event of SN 2009ip based on its late-phase bolometric light curve recently reported. The explosion energy and e…
Extended supernova shock breakout signals from inflated stellar envelopes
Takashi J. Moriya, Debashis Sanyal, Norbert Langer
Stars close to the Eddington luminosity can have large low-density inflated envelopes. We show that the rise times of shock breakout signals from supernovae can be extended signifi…
