Journal ArticleDOI
ULTRA-STRIPPED TYPE Ic SUPERNOVAE FROM CLOSE BINARY EVOLUTION
Thomas M. Tauris,Thomas M. Tauris,Norbert Langer,Takashi J. Moriya,Takashi J. Moriya,Ph. Podsiadlowski,Sung-Chul Yoon,Sergei Blinnikov,Sergei Blinnikov +8 more
TL;DR: In this article, the authors investigated the minimum ejecta mass associated with core-collapse supernovae (SNe) of Type-Ic and showed that mass transfer from a helium star to a compact companion can produce an ultra-stripped core which undergoes iron core collapse and leads to an extremely fast and faint SNIc.
Journal ArticleDOI
Supernovae from red supergiants with extensive mass loss
Takashi J. Moriya,Takashi J. Moriya,Nozomu Tominaga,Nozomu Tominaga,Sergei Blinnikov,P. V. Baklanov,E. I. Sorokina +6 more
TL;DR: In this paper, multicolour light curves (LCs) of supernovae from red supergiants (RSGs) that have exploded within a dense circumstellar medium (CSM) are calculated by using the multigroup radiation hydrodynamics code STELLA.
Journal ArticleDOI
Fallback Supernovae: A Possible Origin of Peculiar Supernovae with Extremely Low Explosion Energies
Takashi J. Moriya,Takashi J. Moriya,Nozomu Tominaga,Nozomu Tominaga,Masaomi Tanaka,Ken'ichi Nomoto,Ken'ichi Nomoto,Daniel Sauer,Paolo A. Mazzali,Keiichi Maeda,Tomoharu Suzuki +10 more
TL;DR: In this article, hydrodynamical calculations of core-collapse supernovae (SNe) with low explosion energies were performed, and it was shown that such fallback SNe can have a variety of light curves (LCs) but their photospheric velocities can only have some limited values with lower limits.
Journal ArticleDOI
Superluminous supernovae
TL;DR: In this article, the three major suggested luminosity sources to explain the huge luminosities of superluminous supernovae are introduced, i.e., the nuclear decay of 56Ni, the interaction between supernova ejecta and dense circumstellar media, and the spin down of magnetars.
Journal ArticleDOI
An analytic bolometric light curve model of interaction-powered supernovae and its application to Type IIn supernovae
Takashi J. Moriya,Takashi J. Moriya,Keiichi Maeda,Francesco Taddia,Jesper Sollerman,Sergei Blinnikov,Sergei Blinnikov,E. I. Sorokina +7 more
TL;DR: In this article, an analytic model for bolometric light curves which are powered by the interaction between supernova ejecta and a dense circumstellar medium is presented, which is aimed at modelling Type IIn supernovae to determine the properties of their supernova ejecteda and circumstellar Medium.
