A Slowly Flattening Milky Way Stellar Disk: Investigating Galactic Warping through Dynamical Orbital Inclinations of Open Clusters
Liming Peng, Zhihong He
By evaluating angular momentum directions of open cluster (OC) samples across various Galactocentric radii, we assessed their orbital plane inclinations. Our findings reveal that,…
