Mapping the Milky Way with Gaia Bp/Rp spectra-IV: the broken and asymmetric density profile of the stellar disk traced by a large sample of red clumps

Wenbo Wu, Yuqin Chen, Jianhui Lian +10

This study explores the density profile of the stellar disk, radially and azimuthally, based on approximately 8.4 million red clump stars selected from Gaia Bp/Rp spectra. After co…

The Milky Way is a less massive galaxy--new estimates of the Milky Way's local and global stellar masses

Jianhui Lian, Tao Wang, Qikang Feng +2

Stellar mass is the most fundamental property of a galaxy. While it has been robustly measured for millions of external galaxies, it remains poorly constrained for the Milky Way be…

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…

The size of the Milky Way galaxy

Jianhui Lian, Gail Zasowski, Bingqiu Chen +4

The size of a galaxy is one of the fundamental parameters that reflects its growth and assembly history. Traditionally, the size of the Milky Way has been characterized by the scal…

The wave-like disk oscillations of mono-age stellar populations in the Solar neighbourhood from Gaia DR3

Tao Wang, Bing-Qiu Chen, Jian-Hui Lian +2

The North-South asymmetry in the number density and bulk velocity of stars in the solar neighborhood provides valuable insights into the formation and evolution of the Milky Way di…
