The optically thick rotating magnetic wind from a massive white dwarf merger product -- II. axisymmetric magnetohydrodynamic simulations
Yici Zhong, Kazumi Kashiyama, Shinsuke Takasao +2
We numerically construct a series of axisymmetric rotating magnetic wind solutions, aiming at exploring the observation properties of massive white dwarf (WD) merger remnants with…
Diagnosis of Circumstellar Matter Structure in Interaction-powered Supernovae with Hydrogen Line Feature
Ayako T. Ishii, Yuki Takei, Daichi Tsuna +2
Some supernovae (SNe) are powered by collision of the SN ejecta with a dense circumstellar matter (CSM). Their emission spectra show characteristic line shapes of combined broad em…
Simulating Hydrogen-poor Interaction-Powered Supernovae with CHIPS
Yuki Takei, Daichi Tsuna, Takatoshi Ko +1
We present the updated open-source code Complete History of Interaction-Powered Supernovae (CHIPS) that can be applied to modeling supernovae (SNe) arising from an interaction with…
MASTER OT J030227.28+191754.5: a dwarf nova at a massive oxygen-neon white-dwarf system ?
Mariko Kimura, Kazumi Kashiyama, Toshikazu Shigeyama +3
We present timing and spectral analysis results of the {\it NICER} and {\it NuSTAR} observations of the dwarf nova MASTER OT J030227.28191754.5 during the 2021--2022 outburst. T…
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…
Initial Flash and Spectral Formation of Type Ia Supernovae with An Envelope: Applications to Over-luminous SNe Ia
Keiichi Maeda, Ji-an Jiang, Mamoru Doi +2
Over-luminous type Ia supernovae (SNe Ia) show peculiar observational features, for which an explosion of a super-massive white dwarf (WD) beyond the classical Chandrasekhar-limiti…
