A Helium-shell Burning Blue Horizontal Branch Star Produced from Common Envelope Evolution
Jiao Li, Changqing Luo, Hai-Liang Chen +16
Observationally, blue horizontal branch (BHB) stars are defined as hot stars occupying a characteristic region between the extreme blue horizontal branch and RR Lyrae variables in…
Environmental dependence of Type Ia supernova standardization on the local luminosity-weighted age
Yuhui Zhang, Xiangcun Meng, Jingxiao Luo +3
Context. The dependence of Type Ia supernova (SN Ia) standardised luminosity on host galaxy properties is a major source of uncertainty in cosmology. As next-generation surveys lik…
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…
Revisiting atmospheric Roche lobe overflow in symbiotic binaries
Tan Liu, Natalia Ivanova, Philipp Podsiadlowski +5
Classical binary evolution models predict dynamically unstable mass transfer in symbiotic stars with high mass ratios, leading to a common envelope. However, many observed S-type s…
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…
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…
SN 2024gy: Multi-epoch Spectroscopic Features Suggestive of Delayed Detonation in a Type Ia Supernova
Liping Li, Zhenyu Wang, Jialian Liu +28
We present photometric and spectroscopic observations of SN 2024gy, a Type Ia supernova (SN Ia) exhibiting high-velocity features (HVFs) in its early-time spectra. This SN reaches…
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…
Do SN 2002cx-like and SN Ia-CSM objects share the same origin?
X. Meng, Ph. Podsiadlowski
SN 2002cx-like and SN Ia-CSM objects show similar early spectra and both belong to a young stellar population, suggesting that they could share the same progenitor origin. Adopting…
