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…
Comparative analysis of missing data imputation methods for CSST survey: Impact on photometric redshift estimation performance
Ling Wang, Zhu Chen, Zhijian Luo +42
Improving the accuracy of photometric redshifts (photo-) is essential for reliable statistical studies of cosmology and galaxy evolution. However, missing photometric bands are…
Identification of a dwarf galaxy stream in Gaia, and its possible association with the VPOS structure
Hao Tian, Chao Liu, Xiang-Xiang Xue +6
Low surface density streams are important tracers to study the formation and evolution of the Milky Way. Using the accurate astrometric measurements from Gaia mission, we discover…
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…
A New Tidal Stream Discovered in Gaia DR3
Hao Tian, Chao Liu, Changqing Luo +2
Thanks to the precise astrometric measurements of proper motions by the Gaia mission, a new tidal stellar stream has been discovered in the northern hemisphere. The distribution of…
TYC 3340-2437-1: A Quadruple System with A Massive Star
Jiao Li, Chao Liu, Changqing Luo +10
Hierarchical massive quadruple systems are ideal laboratories for examining the theories of star formation, dynamical evolution, and stellar evolution. The successive mergers of hi…
Evolved Massive Stars at Low-metallicity VII. the Lower Mass Limit of Red Supergiant Population in the Large Magellanic Cloud
Ming Yang, Bo Zhang, Biwei Jiang +8
The precise definition of the lower mass limit of red supergiant stars (RSGs) is an open question in astrophysics and does not attract too much attention. Here we assemble a spectr…
