Divergent Evolution of Radial Metallicity Gradients in the Thin and Thick Disks of the Milky Way

Weixiang Sun, Gaohuan Long, Hui Li +6

Using 200,388 red clump stars from LAMOST and APOGEE, we investigate the radial metallicity gradients of the Galactic disk as a function of vertical height and stellar age. The thi…

The Kinematic Signature of the Warp and Waves in the Milky Way Disk

Weixiang Sun, Han Shen, Biwei Jiang +1

Using over 170,000 red clump (RC) stars selected from LAMOST and APOGEE, we conduct a detailed analysis of the stellar as a function of (or ) across differen…

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…

The Age-velocity Dispersion Relations of the Galactic Disk as Revealed by the LAMOST-Gaia Red Clump Stars

Weixiang Sun, Han Shen, Biwei Jiang +1

Using nearly 230,000 red clump (RC) stars selected from LAMOST and Gaia, we conduct a comprehensive analysis of the stellar age-velocity dispersion relations (AVRs) for various dis…

The Galactic Disk North-south Asymmetry in Metallicity May Be A New Tracer for the Disk Warp

Weixiang Sun, Han Shen, Biwei Jiang +1

Galactic disk warp has been widely characterized by stellar distributions and stellar kinematics but has not been traced by stellar chemistry. Here, we use a sample with over 170,0…

Orbits and vertical height distribution of 4006 open clusters in the Galactic disk using Gaia DR3

Geeta Rangwal, Aman Arya, Annapurni Subramaniam +2

Open clusters (OCs) in the Galaxy are excellent probes for tracing the structure and evolution of the Galactic disk. We present an updated catalog of parameters for 1,145 OCs, esti…

On the chemical and kinematic signatures of the resonances of the Galactic bar as revealed by the LAMOST-APOGEE red clump stars

Weixiang Sun, Han Shen, Biwei Jiang +1

The Milky Way is widely considered to exhibit features of a rotational bar or quadrupole bar. In either case, the feature of the resonance of the Galactic bar should be present in…

Mapping the Chemo-dynamics of the Galactic disk using the LAMOST and APOGEE red clump stars

Weixiang Sun, Han Shen, Biwei Jiang +1

A detailed measurement is made of the metallicity distributions, kinematics and dynamics of the thin and thick disks, across a large disk volume (5.0 15.0 kpc and…
