Discovery of Stable Titanium at the Northeastern Jet of Cassiopeia A: Need for a Weak Jet Mechanism?
Takuma Ikeda, Yasunobu Uchiyama, Toshiki Sato +3
The origin of the jet-like structures observed in Cassiopeia A is still unclear, although it seems to be related to its explosion mechanism. X-ray observations of the characteristi…
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…
Discovery of the Highly-Neutronized Ejecta Clump with Enhanced Abundances of Titanium and Chromium in the Type Ia Supernova Remnant 3C 397
Yuken Ohshiro, Hiroya Yamaguchi, Shing-Chi Leung +7
The supernova remnant (SNR) 3C 397 is thought to originate from a Type Ia supernova (SN Ia) explosion of a near-Chandrasekhar-mass () progenitor, based on the enhanced…
On the origin of the asymmetry of the ejecta structure and explosion of G350.10.3
Tomoya Tsuchioka, Yasunobu Uchiyama, Ryota Higurashi +4
We present X-ray analysis of the ejecta of supernova remnant G350.10.3 observed with Chandra and Suzaku, and clarify the ejecta's kinematics over a decade and obtain a new obser…
From supernova to supernova remnant: comparison of thermonuclear explosion models
Gilles Ferrand, Donald C. Warren, Masaomi Ono +6
Progress in the three-dimensional modeling of supernovae (SN) prompts us to revisit the supernova remnant (SNR) phase. We continue our study of the imprint of a thermonuclear explo…
Formation pathway for lonely stripped-envelope supernova progenitors: implications for Cassiopeia A
Ryosuke Hirai, Toshiki Sato, Philipp Podsiadlowski +2
We explore a new scenario for producing stripped-envelope supernova progenitors. In our scenario, the stripped-envelope supernova is the second supernova of the binary, in which th…
