Kinematic and Chemical Constraints on the Formation of M31’s Inner and Outer Halo
Kinematic and Chemical Constraints on the Formation of M31’s Inner and Outer Halo
The halo of M31 shows a wealth of substructures, some of which are consistent with assembly from satellite accretion. Here we report on kinematic and abundance results from Keck DEIMOS spectroscopy in the near-infrared calcium triplet region of over 3500 red giant star candidates along the minor axis and in …
