Post-merger rotational evolution of magnetised single hot subdwarfs results in slow rotation due to magnetic braking
Facundo D. Moyano, Zhengwei Liu, Zhanwen Han +3
Single hot subdwarfs are believed to form through mergers of helium-core white dwarfs, which can lead to large-scale magnetic fields generated during the merger, and may be observa…
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…
Three-Dimensional Simulations of Type Ia Supernova Remnants I: Effects of a Main-Sequence Companion Star
Jingxiao Luo, Gilles Ferrand, Zhengwei Liu +2
Type Ia supernovae (SNe Ia) serve as one of cosmic standard candles, but their exact progenitor channel is still an open question. SNe Ia commonly come from binary star evolution.…
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…
Unraveling the mysteries of supernovae with SKA+VLBI
Tao An, Zhengwei Liu, Ailing Wang +6
Supernovae (SNe) drive cosmic chemical enrichment and shape galactic feedback, yet the link between progenitors and explosion outcomes remains poorly constrained because the earlie…
Formation of Extremely Low-mass White Dwarf Binaries Undergoing Enhanced Angular Momentum Loss
Ziqi Zhao, Zhenwei Li, Zhengwei Liu +6
Extremely low-mass white dwarfs (ELM WDs) are helium (He) WDs with masses below , mainly formed through binary interaction. ELM WD binaries typically are forme…
Asteroseismic rotation rates of hot subdwarf B stars hint at transient accretion from leftover common envelope matter
Facundo D. Moyano, Hongwei Ge, Zhanwen Han +6
Asteroseismology enabled measuring the rotation rate in the deep stellar interiors of stars across several evolutionary phases, advancing the theory of angular momentum transport i…
SN2024abfl: A Low-Luminosity Type IIP Supernova at the Low-Mass End of Core Collapse
Luhan Li, Jujia Zhang, Zeyi Zhao +8
We present optical photometric and spectroscopic observations of the low-luminosity (LL) Type IIP supernova SN\,2024abfl. The distance to its host galaxy is highly uncertain, with…
Expected evolution of the binary system ATLAS J1138-5139
Jing-Qi Chen, Hai-Liang Chen, Zheng-Wei Liu +2
ATLAS J1138-5139 is a newly detected ultra-compact double white dwarf (DWD) system which is composed of a carbon-oxygen white dwarf (CO WD) and a $0.24\,M_{\odot}…
Millisecond Pulsars in M2: New discoveries and a detailed timing analysis
Baoda Li, Kuo Liu, Lin Wang +13
Globular clusters (GCs) offer a unique environment for discovering and studying millisecond pulsars. In this paper, we present a multi-epoch search and detailed timing analysis of…
SEDONA-GesaRaT: an AI-Accelerated Radiative Transfer Program for 3-D Supernova Simulations
Xingzhuo Chen, Ulisses Braga-Neto, Lifan Wang +5
We present SEDONA-GesaRaT, a rapid code for supernova radiative transfer simulation developed based on the Monte-Carlo radiative transfer code SEDONA. We use a set of atomic physic…
Producing type Ia supernovae from hybrid CONe white dwarfs with main-sequence binary companions at low metallicity of Z = 0.0001
Boyang Guo, Xiangcun Meng, Zhijia Tian +2
The nature of progenitors of Type Ia supernovae (SNe Ia) and their explosion mechanism remain unclear. It has been suggested that SNe Ia may be resulted from thermonuclear explosio…
The Red Supergiant Progenitor of the Type II Supernova 2024abfl
Jingxiao Luo, Lifu Zhang, Bing-Qiu Chen +9
Linkage between core-collapse supernovae (SNe) and their progenitors is not fully understood and ongoing effort of searching and identifying the progenitors is needed. $\mathrm{SN\…
A potential mass-gap black hole in a wide binary with a circular orbit
Wang Song, Zhao Xinlin, Feng Fabo +28
Mass distribution of black holes identified through X-ray emission suggests a paucity of black holes in the mass range of 3 to 5 solar masses. Modified theories have been devised t…
Using CSST and ejecta-wind interaction in type II-P supernovae to constrain the wind-mass loss of red supergiant stars
Jingxiao Luo, Luc Dessart, Xuefei Chen +1
The properties of H-rich, type II-plateau supernova (SN II-P) progenitors remain uncertain, and this is primarily due to the complexities associated with red supergiant (RSG) wind-…
