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, multicolor light curves (LCs) of supernovae from red supergiants (RSGs) exploded within dense circumstellar medium (CSM) are calculated by using a multi-group radiation hydrodynamics code STELLA.
Journal ArticleDOI
A Long-duration Luminous Type IIn Supernova KISS15s: Strong Recombination Lines from the Inhomogeneous Ejecta-CSM Interaction Region and Hot Dust Emission from Newly Formed Dust
Mitsuru Kokubo,Kazuma Mitsuda,Tomoki Morokuma,Tomoki Morokuma,Nozomu Tominaga,Nozomu Tominaga,Masaomi Tanaka,Takashi J. Moriya,Peter Yoachim,Željko Ivezić,Shigeyuki Sako,Mamoru Doi +11 more
TL;DR: In this article, an SN1988Z-like supernova KISS15s was found in a low-mass star-forming galaxy at redshift z=0.038 during the course of the Kiso Supernova Survey (KISS).
Journal ArticleDOI
Properties of magnetars mimicking 56Ni-powered light curves in Type Ic superluminous supernovae
TL;DR: In this article, the conditions for magnetars under which their spindown energy input can behave like the 56Ni nuclear decay energy input were investigated, and it was shown that an initial magnetic field strength within a certain range is sufficient to keep the magnetar energy deposition within a factor of a few of the 56Co decay energy for several hundreds of days.
Journal ArticleDOI

TL;DR: Hsiao et al. as discussed by the authors showed that the optical spectrum is typical of a super-Chandrasekhar-like SN Ia, but the light curves are unlike those of any SNe Ia observed.
Journal ArticleDOI
iPTF14hls as a variable hyper-wind from a very massive star
TL;DR: In this article, the authors proposed that iPTF14hls was not a sudden outburst like supernovae, but rather a long-term outflow similar to stellar winds.
