Formation rate of LB-1-like systems through dynamical interactions
Ataru Tanikawa, Tomoya Kinugawa, Jun Kumamoto +1
We estimate formation rates of LB-1-like systems through dynamical interactions in the framework of the theory of stellar evolution before the discovery of the LB-1 system. The LB-…
An optical search for transients lasting a few seconds
Michael W. Richmond, Masaomi Tanaka, Tomoki Morokuma +37
Using a prototype of the Tomo-e Gozen wide-field CMOS mosaic camera, we acquire wide-field optical images at a cadence of 2 Hz and search them for transient sources of duration 1.5…
Probe for Type Ia supernova progenitor in decihertz gravitational wave astronomy
Tomoya Kinugawa, Hiroki Takeda, Ataru Tanikawa +1
It is generally believed that Type Ia supernovae are thermonuclear explosions of carbon-oxygen white dwarfs (WDs). However, there is currently no consensus regarding the events lea…
Double-Detonation Models for Type Ia Supernovae: Trigger of Detonation in Companion White Dwarfs and Signatures of Companions' Stripped-off Materials
Ataru Tanikawa, Ken'ichi Nomoto, Naohito Nakasato +1
We have studied double-detonation explosions in double-degenerate (DD) systems with different companion white dwarfs (WD) for modeling type Ia supernovae (SNe Ia) by means of high-…
Rapid Transients Originating from Thermonuclear Explosions in Helium White Dwarf Tidal Disruption Events
Kojiro Kawana, Keiichi Maeda, Naoki Yoshida +1
We study the emission properties of thermonuclear explosions in a helium white dwarf (WD) tidal disruption event (TDE). We consider a TDE where a 0.2 helium WD is disru…
Fitting formulae for evolution tracks of massive stars under extreme metal poor environments for population synthesis calculations and star cluster simulations
Ataru Tanikawa, Takashi Yoshida, Tomoya Kinugawa +2
We have devised fitting formulae for evolution tracks of massive stars with under extreme metal poor (EMP) environments for $\log (Z/Z_\odot) =…
