Journal ArticleDOI
Magnetar-Powered Supernovae in Two Dimensions. II. Broad-Line Supernovae Ic
Ke-Jung Chen,Takashi J. Moriya,Stan Woosley,Tuguldur Sukhbold,Daniel J. Whalen,Yudai Suwa,Volker Bromm +6 more
TL;DR: In this article, two-dimensional hydrodynamical simulations of magnetar-powered supernovae (SNe) driven by disk winds and jets with the CASTRO code were performed to investigate the effect of the central engine on nucleosynthetic yields, mixing, and light curves.
Journal ArticleDOI
Constraints on the rate of supernovae lasting for more than a year from Subaru/Hyper Suprime-Cam
Takashi J. Moriya,Takashi J. Moriya,Ji-an Jiang,Naoki Yasuda,Mitsuru Kokubo,Kojiro Kawana,Keiichi Maeda,Keiichi Maeda,Yen-Chen Pan,Robert M. Quimby,Robert M. Quimby,Nao Suzuki,Ichiro Takahashi,Masaomi Tanaka,Nozomu Tominaga,Nozomu Tominaga,Ken'ichi Nomoto,Jeff Cooke,Lluís Galbany,Santiago González-Gaitán,Chien-Hsiu Lee,Giuliano Pignata +21 more
TL;DR: In this article, the authors conducted a long-term deep transient survey using Hyper Suprime-Cam (HSC) on the 8.2m Subaru telescope and found that about 40% of Type IIn supernovae have long-lasting light curves.
Journal ArticleDOI
Supernova Optical Observations and Theory
TL;DR: In this paper, a review of the emission processes within the supernova (SN) ejecta is presented, and the application of the theory to observational data is presented. But it is not shown how to obtain a complete view of the ejecta.
Journal ArticleDOI
A Multiwavelength View of the Rapidly Evolving SN 2018ivc: An Analog of SN IIb 1993J but Powered Primarily by Circumstellar Interaction
Keiichi Maeda,Poonam Chandra,Takashi J. Moriya,A. Reguitti,Stuart D. Ryder,T. Matsuoka,Tomonari Michiyama,Giuliano Pignata,Daichi Hiramatsu,K. Azalee Bostroem,Esha Kundu,Hanindyo Kuncarayakti,Melina C. Bersten,David Pooley,Shiu-Hang Lee,Daniel J. Patnaude,Ósmar Rodríguez,Gastón Folatelli +17 more
TL;DR: In this article , the authors present the results of prompt follow-up observations of SN 2018ivc with the Atacama Large Millimeter/submillimeter Array, which suggests that it is intrinsically an SN IIb-like explosion of an He star with a modest (∼0.5 − 1M ⊙) extended H-rich envelope.
Journal ArticleDOI
Mass loss of massive helium star supernova progenitors shortly before explosion constrained by supernova radio properties
Takashi J. Moriya,Sung-Chul Yoon +1 more
TL;DR: In this paper , the authors estimate the rise time and peak luminosity distributions of Type-Ibc supernovae in radio based on a few massive helium star mass-loss prescriptions and compare them with the observed distribution to constrain the uncertain mass loss rates.
