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…
Boil-off of red supergiants: mass loss and type II-P supernovae
Jim Fuller, Daichi Tsuna
The mass loss mechanism of red supergiant stars is not well understood, even though it has crucial consequences for their stellar evolution and the appearance of supernovae that oc…
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…
Search for a Black Hole Binary in Gaia DR3 Astrometric Binary Stars with Spectroscopic Data
Ataru Tanikawa, Kohei Hattori, Norita Kawanaka +3
We report the discovery of a candidate binary system consisting of a black hole (BH) and a red giant branch star from the Gaia DR3. This binary system is discovered from 64108 bina…
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…
