Stage-dependent superhump waveform evolution and non-stationary positive-superhump timing in the near-period-gap dwarf nova YZ Cancri
Zhibin Dai, Xuefei Chen, Zhanwen Han
We present a photometric and timing study of the near-period-gap SU~UMa-type dwarf nova YZ~Cancri, based on nearly continuous Transiting Exoplanet Survey Satellite (TESS) photometr…
A Catalog of 45,206 Hα Emission-line Stars from LAMOST MRS DR7
Lihuan Yu, Jiangdan Li, Jinliang Wang +2
Stars that exhibit prominent emission lines in their spectra are referred to as emission-line stars, encompassing a wide range of stellar types and indicative of intriguing physica…
A New Algol-type Binary with an Accretion disk
Tongyu He, Jiao Li, Xiaobin Zhang +10
We present a comprehensive photometric and spectroscopic analysis of the Algol-type binary \textit{Gaia} DR3 1892576067672499328. We identified the system as a spectroscopic binary…
Enhanced magnetic activity in rapidly rotating binary stars
Jie Yu, Charlotte Gehan, Saskia Hekker +12
Stellar activity is fundamental to stellar evolution and the formation and habitability of exoplanets. The interaction between convective motions and rotation in cool stars results…
Mass, Luminosity, and Stellar Age of Early-type Stars from the LAMOST Survey
Qida Li, Jianping Xiong, Jiao Li +4
Mass () and luminosity () are fundamental parameters of stars but can only be measured indirectly. Typically, effective temperature (), surface gravity (${\rm lo…
Identify Main-sequence Binaries from the Chinese Space Station Telescope Survey with Machine Learning. II. Based on Gaia and GALEX
Jia-jia Li, Jian-ping Xiong, Zhi-jia Tian +3
The statistical characteristics of double main-sequence (MS) binaries are essential for investigating star formation, binary evolution, and population synthesis. Our previous study…
Detection of Ubiquitous Circumbinary Matter in Hot Subdwarfs Formed from Common-Envelope Ejections
Jiangdan Li, Christian Wolf, Jiao Li +7
The formation of compact binary systems is largely driven by their evolution through a common envelope (CE) phase, crucial for understanding phenomena such as type Ia supernovae an…
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…
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\…
Discoveries and Properties of EL CVn-type Binaries in the TESS Survey
Jianping Xiong, Zhenwei Li, Jiao Li +5
EL CVn-type systems represent a rare evolutionary stage in binary star evolution, providing ideal laboratories for investigating stable mass transfer processes and the formation of…
Ultraluminous X-ray sources with He star companions
Luhan Li, Bo Wang, Dongdong Liu +3
Ultraluminous X-ray sources (ULXs) are non-nuclear point-like objects observed with extremely high X-ray luminosity that exceeds the Eddington limit of a black hol…
A born ultramassive white dwarf-hot subdwarf super-Chandrasekhar candidate
Changqing Luo, Jiao Li, Chuanjie Zheng +16
Although supernovae is a well-known endpoint of an accreting white dwarf, alternative theoretical possibilities has been discussing broadly, such as the accretion-induced collapse…
Formation of millisecond pulsars with wide orbits
Bo Wang, Dongdong Liu, Yunlang Guo +4
Millisecond pulsars (MSPs) are a kind of radio pulsars with short spin periods, playing a key role in many aspects of stellar astrophysics. In recent years, some more MSPs with wid…
Mass retention efficiencies of He accretion onto carbon-oxygen white dwarfs and type Ia supernovae
C. Wu, B. Wang, D. Liu +1
Type Ia supernovae (SNe Ia) play a crucial role in studying cosmology and galactic chemical evolution. They are thought to be thermonuclear explosions of carbon-oxygen white dwarfs…
The Formation of EL CVn-type Binaries
Chen Xuefei, Maxted P. F. L., Li Jiao +1
EL CVn-type binaries contain an A-type dwarf star and a very low mass () helium white dwarf precursor (pre-He WD). Recent surveys and observations have discovered…
