Relativistic supernova ejecta colliding with a circumstellar medium: an application to the low-luminosity GRB 171205A
Akihiro Suzuki, Keiichi Maeda, Toshikazu Shigeyama
We perform multi-wavelength light curve modeling of the recently discovered low-luminosity gamma-ray burst (GRB) 171205A. The emission model is based on the relativistic ejecta-cir…
Extended Optical/NIR Observations of Type Iax Supernova 2014dt: Possible Signatures of a Bound Remnant
Miho Kawabata, Koji S. Kawabata, Keiich Maeda +19
We present optical and near-infrared observations of the nearby Type Iax supernova (SN) 2014dt from 14 to 410 days after the maximum light. The velocities of the iron absorption li…
Supernova Nebular Spectroscopy Suggests a Hybrid Envelope-Stripping Mechanism for Massive Stars
Qiliang Fang, Keiichi Maeda, Hanindyo Kuncarayakti +2
When nuclear fuel in the core of a massive star with a zero-age main-sequence mass is exhausted, the central part of the iron or magnesium core coll…
The origin of the H-like structure in nebular spectra of type IIb supernovae
Qiliang Fang, Keiichi Maeda
We investigate the origin of the H-like structure seen in late-phase nebular spectra of type IIb supernovae (SNe IIb) at days after the explosion. We compare the lumi…
Surface Radioactivity or Interactions? Multiple Origins of Early-excess Type Ia Supernovae and Associated Subclasses
Ji-an Jiang, Mamoru Doi, Keiichi Maeda +1
Early-phase Type Ia supernovae (SNe Ia), especially those with luminosity enhancement within the first few days of explosions ("early-excess SNe Ia"), play an irreplaceable role in…
The Fast, Luminous Ultraviolet Transient AT2018cow: Extreme Supernova, or Disruption of a Star by an Intermediate-Mass Black Hole?
Daniel A. Perley, Paolo A. Mazzali, Lin Yan +60
Wide-field optical surveys have begun to uncover large samples of fast (t_rise < 5d), luminous (M_peak < -18), blue transients. While commonly attributed to the breakout of a super…
