Direct Detection of Type II-P Supernova Progenitors with the and CSST Surveys
Junjie Wu, Ning-Chen Sun, Zexi Niu +14
Identifying and characterizing supernova (SN) progenitor stars remains a central yet difficult goal in SN research, limited by archival images lacking sufficient depth or spatial r…
The origin of B-type runaway stars based on kinematics
Yanjun Guo, Chao Liu, ZhiCun Liu +5
Runaway stars depart their birthplaces with high peculiar velocities. Two mechanisms are commonly invoked to explain their origin, the binary supernova scenario (BSS) and the dynam…
Surface brightness-color relations for red giant branch stars using asteroseismic radii and Gaia distances (the ARD method)
Jianping Xiong, Qiyuan Cheng, Xiaodian Chen +4
Aims. Asteroseismic radius and Gaia distance (ARD) method has been proposed to establish the SBCRs for late-type stars. Methods. We select Kepler RGB stars with high-precision aste…
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…
Investigating the Behavior and Spatiotemporal Variations of Green Line Emission in the Solar Corona
Jacob Oloketuyi, Yu Liu, Linhua Deng +6
Understanding coronal structure and dynamics can be facilitated by analyzing green-line emission, which enables the investigation of diverse coronal structures such as coronal loop…
Hubble Space Telescope survey of Magellanic Cloud star clusters. Binaries among the split main sequences of NGC 1818, NGC 1850, and NGC 2164
F. Muratore, A. P. Milone, F. D'Antona +15
Nearly all star clusters younger than ~600 Myr exhibit extended main sequence turn offs and split main sequences (MSs) in their color-magnitude diagrams. Works based on both photom…
