High-entropy ejecta plumes in Cassiopeia A from neutrino-driven convection
Toshiki Sato, Keiichi Maeda, Shigehiro Nagataki +6
Recent multi-dimensional simulations suggest that high-entropy buoyant plumes help massive stars to explode. Outwardly protruding iron-rich fingers in the galactic supernova remnan…
A study of Si II and S II features in spectra of Type Ia supernova
Xulin Zhao, Keiichi Maeda, Xiaofeng Wang +1
We studied the spectral features of Si II 4130, 5972, 6355 and S II W-trough for a large sample of Type Ia supernovae (SNe Ia). We find that in NV (Normal-Velocity) subclass of…
Rapid Deceleration of Blast Waves Witnessed in Tycho's Supernova Remnant
Takaaki Tanaka, Tomoyuki Okuno, Hiroyuki Uchida +4
In spite of their importance as standard candles in cosmology and as major major sites of nucleosynthesis in the Universe, what kinds of progenitor systems lead to type Ia supernov…
The electron-capture origin of supernova 2018zd
Daichi Hiramatsu, D. Andrew Howell, Schuyler D. Van Dyk +27
In the transitional mass range ( 8-10 solar masses) between white dwarf formation and iron core-collapse supernovae, stars are expected to produce an electron-capture superno…
Application of The Wind-Driven Model to A Sample of Tidal Disruption Events
Kohki Uno, Keiichi Maeda
An origin of the Optical/UV radiation from tidal disruption events (TDEs) has recently been discussed for different scenarios, but observational support is generally missing. In th…
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…
