A Radiation-Hydrodynamic Light Curve Grid and Interpolation Framework for Stripped-Envelope Supernovae
Qiliang Fang, Takashi J. Moriya
We present a grid of 8,148 stripped-envelope supernovae (SESNe) light curves based on radiation hydrodynamic simulations of exploding helium-star progenitors. The grid spans an eje…
Radio Constraints on the Circumstellar Environment of the Type IIb Supernova SN 2024iss
Yuhei Iwata, Tomoki Matsuoka, Masanori Akimoto +6
Type~IIb supernovae exhibit diverse progenitor properties, and radio observations offer a unique probe of their mass-loss histories shortly before the explosion. We present Japanes…
The double white dwarf merger model for the progenitors of SN 2021yfj-like events
Dongdong Liu, Chengyuan Wu, Takashi J. Moriya +4
Context. Recently, a new class of supernovae with prominent narrow emission features of Si, S and Ar has been reported, i.e. SN 2021yfj-like events (SNe Ien). Their progenitor orig…
Surrogate models for type II supernovae: Probing low-energy explosions and interaction-free regimes
Zhengyang Zhang, Shuai Zha, Nikhil Sarin +3
To address the computational bottleneck of analyzing type II supernova samples from surveys such as the Legacy Survey of Space and Time, we present two STELLA-based neural-network…
Superlinear Type II Superluminous Supernovae 2017fck and 2019cmv: A Possible Origin from Interacting Thermonuclear Supernovae
Daichi Hiramatsu, Takashi J. Moriya, D. Andrew Howell +9
Additional power sources to traditional supernovae (SNe) are necessary to account for the extreme luminosities of superluminous SNe (SLSNe). A main power source for hydrogen-rich S…
The JADES Transient Survey III: Linking Core-Collapse Supernova Rates to Cosmic Star Formation
Christian Vassallo, Seppo Mattila, Christa DeCoursey +24
The paper uses JWST JADES transient survey data to compare core‑collapse supernova rates with cosmic star‑formation rate densities from redshift 0 to 5, exploring the impact of the…
