Influence of mass-transfer stability on the formation of post-common-envelope binaries
Yanxu Shi, Hongwei Ge, Zhenwei Li +9
Post-common-envelope binaries are the natural laboratories for constraining the physics of common envelope evolution, which is one of the most uncertain phases in binary stellar ev…
Surface brightness-color relations for red giant branch stars: Observational constraints on metallicity effects using the ARD method
Jianping Xiong, Xiaodian Chen, Jiao Li +5
Aims: We aim to quantify the metallicity dependence of the SBCR for red giant branch (RGB) stars and to test the robustness of the relation using asteroseismic radii, Gaia distance…
Empirical colour--effective temperature relations in the SDSS system from IRFM temperatures of GALAH and APOGEE stars
Zenghua Zhou, Luca Casagrande, Xiaobin Zhang +5
Reliable estimates of stellar effective temperature () are fundamental to stellar population studies and Galactic astrophysics. However, the majority of stars ob…
Recalibration of SDSS photometric zero-points based on the InfraRed Flux Method temperature scale
Zenghua Zhou, Luca Casagrande, Heran Xiong +4
Accurate photometric zero-points are essential for translating observed magnitudes into physical fluxes, from comparing with models to ensuring consistency across surveys. We deter…
Pre-Supernova Eruptions Triggered by Sudden Energy Deposition in Low-Mass Core-Collapse Supernova Progenitors
Shuai Zha, Han Lin, Xuefei Chen +1
In low-mass core-collapse supernova (CCSN) progenitors, nuclear burning beyond oxygen can become explosive under degenerate conditions, triggering eruptive mass loss before the fin…
Introduction to the Chinese Space Station Survey Telescope (CSST)
CSST Collaboration, Yan Gong, Haitao Miao +119
The Chinese Space Station Survey Telescope (CSST) is an upcoming Stage-IV sky survey telescope, distinguished by its large field of view (FoV), high image quality, and multi-band o…
