SN 2016iyc: A Type IIb supernova arising from a low-mass progenitor
Amar Aryan, S. B. Pandey, WeiKang Zheng +12
In this work, photometric and spectroscopic analyses of a very low-luminosity Type IIb supernova (SN) 2016iyc have been performed. SN 2016iyc lies near the faint end among the dist…
Are stripped envelope supernovae really deficient in Ni?
Ryoma Ouchi, Keiichi Maeda, Joseph P. Anderson +1
Recent works have indicated that the Ni masses estimated for Stripped Envelope SNe (SESNe) are systematically higher than those estimated for SNe II. Although this may sugge…
Progenitor mass constraints for the type Ib intermediate-luminosity SN 2015ap and the highly extinguished SN 2016bau
Amar Aryan, S. B. Pandey, WeiKang Zheng +21
Photometric and spectroscopic analyses of the intermediate-luminosity Type Ib supernova (SN) 2015ap and of the heavily reddened Type Ib SN~2016bau are discussed. Photometric proper…
The pre-SN activity as a possible explanation of the peculiar properties of Type IIP Supernova 2009kf
Ryoma Ouchi, Keiichi Maeda
SN 2009kf is an exceptionally bright Type IIP Supernova (SN IIP) discovered by the Pan-STARRS 1 survey. The -band magnitude at the plateau phase is mag, which is…
Constraining massive star activities in the final years through properties of supernovae and their progenitors
Ryoma Ouchi, Keiichi Maeda
Recent observations of supernovae (SNe) just after the explosion suggest that a good fraction of SNe have the confined circumstellar material (CSM) in the vicinity, and the pre-SN…
SN 2017czd: A Rapidly Evolving Supernova from a Weak Explosion of a Type IIb Supernova Progenitor
Tatsuya Nakaoka, Takashi J. Moriya, Masaomi Tanaka +10
We present optical and near-infrared observations of the rapidly evolving supernova (SN) 2017czd that shows hydrogen features. The optical light curves exhibit a short plateau phas…
Radii and Mass-loss Rates of Type IIb Supernova Progenitors
Ryoma Ouchi, Keiichi Maeda
Several Type IIb supernovae (SNe IIb) have been extensively studied, both in terms of the progenitor radius and the mass-loss rate in the final centuries before the explosion. Whil…
