Diversity of Type Ia supernova optical light curves among different spectroscopic subclasses
R. B. Koshi, M. Doi, S. Sako +3
Attempts to reveal the spectroscopic diversity of Type Ia supernovae (SNe Ia) have led to subclassification schemes such as the Branch system, which classifies SNe Ia into four cat…
A systematic search for rapid transients in the Subaru HSC-SSP transient survey
Seiji Toshikage, Masaomi Tanaka, Naoki Yasuda +9
Recent high-cadence transient surveys have discovered rapid transients whose light curve timescales are shorter than those of typical supernovae. In this paper, we present a system…
Nebular phase observations of the type-Ib supernova iPTF13bvn favour a binary progenitor
H. Kuncarayakti, K. Maeda, M. C. Bersten +9
Aims. We present and analyse late-time observations of the type-Ib supernova with possible pre-supernova progenitor detection, iPTF13bvn, taken at 300 days after the explosio…
Constraining supernova progenitors: an integral field spectroscopic survey of the explosion sites
H. Kuncarayakti, G. Aldering, J. P. Anderson +9
We describe a survey of nearby core-collapse supernova (SN) explosion sites using integral field spectroscopy (IFS) technique, which is an extension of the work described in Kuncar…
Elemental Abundances in the Possible Type Ia Supernova Remnant G344.7-0.1
Hiroya Yamaguchi, Masaomi Tanaka, Keiichi Maeda +5
Recent studies on the Galactic supernova remnant (SNR) G344.7-0.1 have commonly claimed its origin to be a core-collapse supernova (SN) explosion, based on its highly asymmetric mo…
Nebular Spectra and Explosion Asymmetry of Type Ia Supernovae
Keiichi Maeda, Stefan Taubenberger, Jesper Sollerman +4
The spectral signatures of asymmetry in Type Ia Supernova (SN Ia) explosions are investigated, using a sample of late-time nebular spectra. First, a kinematical model is constructe…
