Delayed Wind Onset in Pa 30, the Remnant of Type Iax SN 1181
Takatoshi Ko, Ryosuke Hirai, Taiga Sasaoka +1
Pa 30 is the recently identified remnant of the historical supernova SN 1181, likely a Type Iax event, and a nebula surrounding the central white dwarf launching a fast wind ($\sim…
Population Synthesis Study on the Binary Origin of Type Ibn Supernovae
Takatoshi Ko, Tomoya Kinugawa, Daichi Tsuna +2
Type Ibn supernovae (SNe) are a class of SN explosions whose progenitors are surrounded by dense helium-rich circumstellar matter (CSM). Some models have been proposed for how to f…
Radio emission from SN 1181 hosting a white dwarf merger product
Takatoshi Ko, Daichi Tsuna, Bunyo Hatsukade +1
The remnant of the historical supernova 1181 is claimed to be associated with a white dwarf merger remnant J005311. The supernova remnant (SNR) shock, and a termination shock expec…
A dynamical model for IRAS 00500+6713: the remnant of a type Iax supernova SN 1181 hosting a double degenerate merger product WD J005311
Takatoshi Ko, Hiromasa Suzuki, Kazumi Kashiyama +6
IRAS 00500+6713 is a hypothesized remnant of a type Iax supernova SN 1181. Multi-wavelength observations have revealed its complicated morphology; a dusty infrared ring is sandwich…
Eruption of the Envelope of Massive Stars by Energy Injection with Finite Duration
Takatoshi Ko, Daichi Tsuna, Yuki Takei +1
A significant fraction of supernovae show signatures of dense circumstellar material (CSM). While multiple scenarios for creating a dense CSM exist, mass eruption due to injection…
