Large Stellar Disks in Small Elliptical Galaxies
Rix, Hans-Walter; Carollo, C Marcella; Freeman, Kenneth
Description
We present stellar kinematics along the principal axes of seven elliptical galaxies less luminous than MB = -19.5, which extend beyond the half-light radii for all systems in this photometrically selected sample. At large radii, the kinematics not only confirm that rotation and "diskiness" are important in faint elliptical galaxies, as was previously known, but show that rotation dominates: the stars at large galactocentric distances have (Vlσ)max ∼ 2, similar to the disks in bona fide S0...[Show more]
