Correlation between the two-armed spiral in the -- plane and moving groups
Yan Xu, Chao Liu, Chengdong Li +5
We use a cross-matched sample of 3.7 million stars from Gaia DR3 and LAMOST DR7 to investigate the velocity substructures in the Milky Way disk. The median radial velocity as…
The extinction distances for over a thousand planetary nebulae with Gaia measurements
Juan Deng, Shu Wang, Biwei Jiang +1
Although Gaia has identified the central stars of planetary nebulae (CSPNe) for about 70% of known Galactic planetary nebulae (PNe), reliable distance estimates remain incomplete,…
A Detailed Analysis of the Milky Way Warp Based on Classical Cepheids
Xiaoyue Zhou, Xiaodian Chen, Licai Deng +3
Classical Cepheids (CCs) are important probes for the large-scale warp structure of the Milky Way. Using Gaia DR3 CCs, we establish an optimal time-dependent warp model, where the…
The Tip of Red Giant Branch Distances to Nearby Dwarf Galaxies WLM and Sextans A with JWST
Ziming Yan, Shu Wang, Xiaodian Chen +1
Distance measurements to extragalactic systems that are both accurate and precise are cornerstones of modern astrophysics, underpinning the calibration of standard candles and the…
Tracing the Galactic disk from the kinematics of Gaia Cepheids
Xiaoyue Zhou, Xiaodian Chen, Licai Deng +1
Classical Cepheids (CCs) are excellent tracers for understanding the structure of the Milky Way disk. The latest Gaia Data Release 3 provides a large number of line-of-sight veloci…
Exploring asymmetric substructures of the outer disk based on the conjugate angle of the radial action
Y. Xu, C. Liu, Z. Li +5
We use the conjugate angle of radial action (), the best representation of the orbital phase, to explore the "mid-plane, north branch, south branch" and "Monoceros area" disk…
