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…
