Identifying Hierarchically Triple Star Systems with Gaia DR3 and LAMOST
Tongyu He, Jiao Li, Jiangdan Li +8
Triple star systems are critical for understanding stellar dynamics and compact objects in astrophysics, yet confirmed hierarchical triples identified via spectroscopy remain limit…
When LAMOST meets Gaia DR3 Exploring the metallicity of open clusters
R. Zhang, Guo-Jian Wang, Yuxi +9
Context. Open clusters (OCs) are valuable probes of stellar population characteristics. Their age and metallicity provide insights into the chemical enrichment history of the Milky…
TV Mon -- post mass transfer Algol type binary with Scuti pulsations in primary component
Mikhail Kovalev, Zhenwei Li, Jianping Xiong +4
We present a study of the detached eclipsing binary TV~Mon using spectra from the LAMOST medium-resolution survey and ASAS-SN, CoRoT photometry. We apply multiple-epochs spectral f…
Estimating the Atmospheric Parameters of Early-type Stars from the Chinese Space Station Telescope (CSST) Slitless Spectra Survey
JiaRui Rao, HaiLiang Chen, JianPing Xiong +6
The measurement of atmospheric parameters is fundamental for scientific research using stellar spectra. The Chinese Space Station Telescope (CSST), scheduled to be launched in 2024…
Type Ia Supernovae from First-generation Stars
Zhenwei Li, Lifan Wang, Zhanwen Han +1
Type Ia Supernovae (SNe Ia) discovered at redshift are presumed to be produced from Population (Pop) I/II stars. {In this work, we investigate the production of SNe…
Adiabatic Mass Loss In Binary Stars. IV. Low and Intermediate Mass Helium Binary Stars
Lifu Zhang, Hongwei Ge, Xuefei Chen +1
The unstable mass transfer situation in binary systems will asymptotically cause the adiabatic expansion of the donor star and finally lead to the common envelope phase. This proce…
