SN 2018hna: 1987A-like supernova with a signature of shock breakout
Avinash Singh, D. K. Sahu, G. C. Anupama +22
High cadence ultraviolet, optical and near-infrared photometric and low-resolution spectroscopic observations of the peculiar Type II supernova (SN) 2018hna are presented. The earl…
Type Ia SN 2019ein: New Insights into the Similarities and diversities among High-Velocity SNe Ia
Miho Kawabata, Keiichi Maeda, Masayuki Yamanaka +38
We present optical observations of type Ia supernova (SN) 2019ein, starting at 2 days after the estimated explosion date. The spectra and the light curves show that SN 2019ein belo…
Multi-band polarization of Type IIP supernovae due to light echo from circumstellar dust
Takashi Nagao, Keiichi Maeda, Masaomi Tanaka
Type IIP supernovae (SNe IIP) often show relatively high continuum polarization (\%) in the late phase. This polarization feature is generally believed to be due to an inne…
Polarization as a probe of dusty environments around Type Ia supernovae: radiative transfer models for SN 2012dn
Takashi Nagao, Keiichi Maeda, Masayuki Yamanaka
Geometry of circumstellar (CS) medium around supernovae (SNe) provides important diagnostics to understand the nature of their progenitors. In this paper, properties of CS dust aro…
Circumstellar Light Echo as a Possible Origin of the Polarization of Type IIP Supernovae
Takashi Nagao, Keiichi Maeda, Masaomi Tanaka
Type IIP supernovae (SNe IIP) are the most common class of core-collapse SNe. They often show rapid increase of polarization degree in the late phase. This time evolution is genera…
OISTER Optical and Near-Infrared Observations of the Super-Chandrasekhar Supernova Candidate SN 2012dn: Dust Emission from the Circumstellar Shell
Masayuki Yamanaka, Keiichi Maeda, Masaomi Tanaka +34
We present extensively dense observations of the super-Chandrasekhar supernova (SC SN) candidate SN 2012dn from to days after the date of its -band maximum in the o…
