Abstract
New photometry of regions beyond the classical tidal radius of Carina exposes a Carina-like stellar distribution that is about 1% of the cen tral surface density and which extends at least as far as 2 degrees (3 .5 kpc) from Carina's center. The detections of a spatially extended R R Lyrae distribution, and a significant Carina-like stellar population at large central distances confirm predictions of the time-dependent tidal interaction model and suggest that Carina is not in virial equil ibrium.
