Characterising the Kinematics and Evolution of Young Stellar Groups within 1 kpc of the Sun Using Gaia DR3
Long-Fei Ding, Yun-Qian Li, Bing-Qiu Chen +2
Star-forming regions are key to understanding the formation and early evolution of stars. Young stellar objects (YSOs) form groups with distinct kinematic and spatial properties, i…
A recent re-acceleration of the Local Bubble revealed by kinematics of young star associations
Guang-Ya Zeng, Guang-Xing Li, Bing-Qiu Chen +2
The low-density region of the interstellar medium (ISM) where the Sun is located is known as the Local Bubble, a cavity filled with high-temperature and low-density plasma that may…
Unveiling a young thick disk in the Milky Way
Jianhui Lian, Min Du, Shuai Lu +5
The thickness of a galaxy's disk provides a valuable probe of its formation and evolution history. Observations of the Milky Way and local galaxies have revealed an ubiquitous disk…
Photometric metallicities of 0.8 million KiDS stars
Bao-Kun Sun, Bing-Qiu Chen, Xiao-Wei Liu
Accurate determinations of metallicity for large, complete stellar samples are essential for advancing various studies of the Milky Way. In this paper, we present a data-driven alg…
Little time for oscillation: Fast disruption of the Radcliffe Wave by Galactic motions
Guang-Xing Li, Ji-Xuan Zhou, Bing-Qiu Chen
The Radcliffe wave \cite{2020Natur.578..237A} is a 2.7 kpc long, 100 pc wide-like structure in the Galactic disk with a wave-like velocity structure \cite{2022MNRAS.517L.102L,2024a…
The Correlation Between Dust and Gas Contents in Molecular Clouds
Rui-Zhi Li, Bing-Qiu Chen, Guang-Xing Li +3
Molecular clouds are regions of dense gas and dust in space where new stars and planets are born. There is a strong correlation between the distribution of dust and molecular gas i…
