Search for Past Stellar Encounters and the Origin of 3I/ATLAS
Yiyang Guo, Luyao Zhang, Fabo Feng +3
3I/ATLAS, the third discovered interstellar object, has a heliocentric speed of 58 km/s and exhibits cometary activity. To constrain the origin of 3I/ATLAS and its past dynamical e…
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…
Radial Wave in the Galactic Disk: New Clues to Discriminate Different Perturbations
Chengye Cao, Zhao-Yu Li, Ralph Schönrich +1
Decoding the key dynamical processes that shape the Galactic disk structure is crucial for reconstructing the Milky Way's evolution history. The second Gaia data release unveils a…
Insight into the Galactic Bulge Chemodynamical Properties from Gaia DR3
Xiaojie Liao, Zhaoyu Li, Iulia Simion +4
We explore the chemodynamical properties of the Galaxy in the azimuthal velocity and metallicity [Fe/H] space using red giant stars from Gaia Data Release 3. The row-normaliz…
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…
On the Migration Origin of the Hercules Moving Group with GAIA, LAMOST, APOGEE, and GALAH Surveys
Xilong Liang, Suk-Jin Yoon, Jingkun Zhao +3
Using Gaia DR3 data and the wavelet transformation technique, we study the substructures of the Hercules moving group (HMG): Hercules 1 (H1) and Hercules 2 (H2). Spectroscopic surv…
