A prolonged plateau-to-tail transition in the Type II supernova SN2025abyc
Luhan Li, Bo Wang, Jujia Zhang +6
We present optical photometric and spectroscopic observations of the Type II supernova SN2025abyc. During the optically thick phase between approximately 10 and 70 d after explosio…
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…
SN 2022erq: A Superluminous Thermonuclear Supernova with Escalating Preexplosion Mass Loss
Qian Zhai, Jujia Zhang, Xiaofeng Wang +51
We present a photometric and spectroscopic study of the superluminous Type Ia supernova SN 2022erq. Its early spectra, dominated by iron-group elements with weak intermediate-mass…
Optical observations on the young Type Ia SN 2021fxy with detached high velocity features
Liping Li, Jujia Zhang, Zhenyu Wang +5
We present optical observations on the young type Ia supernova (SN Ia) SN 2021fxy obtained within a few days after the explosion, with a focus on its prominent high-velocity featur…
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…
X-rays breaking out of pre-explosion ejecta mark a supernova's first light
Weimin Yuan, Qiu-Ju Huang, Jin-Ping Zhu +130
Massive stars die as core-collapse supernovae, whose optical light emerges days after the implosion. Theory predicts that the initial collapse-driven shock, upon breaking through t…
Elemental Abundances from Off-center Carbon Burning in Accreting CO White Dwarfs: Implications for SN 2021yfj-like events
Chengyuan Wu, Dongdong Liu, Takashi J. Moriya +3
SN 2021yfj is a recently discovered interacting supernova that exhibits narrow emission lines of Si, S, and Ar, indicating the presence of circumstellar material (CSM) enriched wit…
Supernovae interacting with Si and S-rich circumstellar matter from double white dwarf mergers
Takashi J. Moriya, Chengyuan Wu, Dongdong Liu +2
We present that supernovae interacting with a dense Si and S-rich circumstellar matter like SN 2021yfj can originate from mergers of two white dwarfs. A C+O white dwarf accreting H…
Evolution Models of CO WD -- AGB Star Merger Remnants
Chengyuan Wu, Heran Xiong, Shi Jia +2
Common envelope evolution is a critical but still poorly understood phase in binary evolution. It plays a key role in forming close binaries such as hot subdwarfs, double white dwa…
Helium-burning blue large-amplitude pulsators: A Population Study with BPASS
Zhengyang Zhang, Conor M. Byrne, Chengyuan Wu +1
Blue Large-Amplitude Pulsators (BLAPs) are a class of radially pulsating stars with effective temperatures ranging from 20,000 to 35,000 K and pulsation periods between 7 and 75 mi…
Binary Evolution Pathways to Blue Large-Amplitude Pulsators: Insights from HD 133729
Zhengyang Zhang, Chengyuan Wu, Xianfei Zhang +2
Blue Large-Amplitude Pulsators (BLAPs) represent a recently identified class of pulsating stars distinguished by their short pulsation periods ( minutes) and asymmetric lig…
He-accreting oxygen-neon white dwarfs and accretion-induced collapse events
Zhengyang Zhang, Chengyuan Wu, Amar Aryan +3
It has been widely accepted that mass-accreting white dwarfs (WDs) are the progenitors of Type Ia supernovae or electron-capture supernovae. Previous work has shown that the accret…
Light curves of the explosion of ONe WD+CO WD merger remnant and type Icn supernovae
Chengyuan Wu, Shuai Zha, Yongzhi Cai +6
Type Icn supernovae (SNe Icn) are a newly detected rare subtype of interacting stripped-envelope supernovae which show narrow P-Cygni lines of highly ionized carbon, oxygen, and ne…
