The Galactic Disk North–South Asymmetry in Metallicity May Be a New Tracer for the Disk Warp
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 170,000 red clump (RC) stars selected from LAMOST and APOGEE first to establish a correlation between the north–south asymmet...
