The Initial Mass Function of the Galactic Early-type Field Stars Based on the LAMOST Survey
Qida Li, Jianping Xiong, Zhenwei Li +4
Research on the high-mass end of the initial mass function (IMF) has been limited due to a scarcity of samples. Recently, Large Sky Area Multi-Object Fiber Spectroscopic Telescope…
PANCAKE: Python bAsed Numerical Color-magnitude-diagram Analysis pacKagE
Yun Zheng, Yujiao Yang, Yong-kun Zhang +11
Stellar populations serve as a fossil record of galaxy formation and evolution, providing crucial information about the history of star formation and galaxy evolution. The color-ma…
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…
Detailed Mapping of the Galactic Disk Structure in the Solar Neighborhood through LAMOST K Dwarfs
Xi-Can Tang, Hao Tian, Jing Li +4
The Galactic disk is one of the main components of the Milky Way, which contributes most of the luminosity. Its structure is essential for understanding the formation and evolution…
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…
North-South asymmetries in the Galactic thin disk associated with the vertical phase spiral as seen using LAMOST-Gaia stars
Jun Lin, Rui Guo, Sarah A. Bird +5
We select 1,052,469 (754,635) thin disk stars from {\it Gaia} eDR3 and LAMOST DR7 in the range of Galactocentric radius (guiding center radius ) from 8 to 11\,kpc…
Potential Impact of the Sagittarius Dwarf Galaxy on the Formation of Young O-rich Stars
Tiancheng Sun, Shaolan Bi, Xunzhou Chen +11
The Milky Way underwent significant transformations in its early history, characterised by violent mergers and satellite galaxy accretion. However, recent observations reveal notab…
Measuring the Milky Way Vertical Potential with the Phase Snail in a Model Independent Way
Rui Guo, Zhao-Yu Li, Juntai Shen +2
The vertical phase-space spiral (snail) is a direct sign of dis-equilibrium of Milky Way's disc. Nevertheless, the wrapping of the phase snail contains information of the vertical…
