Long-term evolution of a supernova remnant hosting a double neutron star binary
Tomoki Matsuoka, Shiu-Hang Lee, Keiichi Maeda +2
An ultra-stripped supernova (USSN) is a type of core-collapse SN explosion proposed to be a candidate formation site of a double neutron star (DNS) binary. We investigate the dynam…
Statistical properties of the nebular spectra of 103 stripped envelope core collapse supernovae
Qiliang Fang, Keiichi Maeda, Hanindyo Kuncarayakti +6
We present an analysis of the nebular spectra of 103 stripped envelope (SE) supernovae (SNe) collected from the literature and observed with the Subaru Telescope from 2002 to 2012,…
Properties of Type Ibn Supernovae: Implications for the Progenitor Evolution and the Origin of a Population of Rapid Transients
Keiichi Maeda, Takashi J. Moriya
Type Ibn Supernovae (SNe Ibn) show signatures of strong interaction between the SN ejecta and hydrogen-poor circumstellar matter (CSM). Deriving the ejecta and CSM properties of SN…
The final months of massive star evolution from the circumstellar environment around SN Ic 2020oi
Keiichi Maeda, Poonam Chandra, Tomoki Matsuoka +8
We present the results of ALMA band 3 observations of a nearby type Ic supernova (SN) 2020oi. Under the standard assumptions on the SN-circumstellar medium (CSM) interaction and th…
Observational properties of a general relativistic instability supernova from a primordial supermassive star
Takashi J. Moriya, Ke-Jung Chen, Kimihiko Nakajima +2
We present the expected observational properties of a general relativistic instability supernova (GRSN) from the 55,500 Msun primordial (Population III) star. Supermassive stars ex…
Constraining red supergiant mass-loss prescriptions through supernova radio properties
Takashi J. Moriya
Supernova properties in radio strongly depend on their circumstellar environment and they are an important probe to investigate the mass loss of supernova progenitors. Recently, co…
