The Internal Kinematics of NGC 2808 and Its Multiple Populations

The Internal Kinematics of NGC 2808 and Its Multiple Populations

We use new Hubble Space Telescope observations coupled with archival data spanning a total temporal baseline of 17 yr to study the internal kinematics of the multiple populations in the globular cluster NGC 2808 from its center out to ∼8 half-light radii ( r _h ). We detect different kinematical beh...
