Session 77 - Normal Galaxies.
Oral session, Thursday, June 13
New observations of the Carina dwarf spheroidal galaxy have been obtained at angular distances as far as 2 degrees from its center. Along the Carina major axis we detect RR Lyraes at Carina's MW distance, but well beyond its classical tidal radius. Color-magnitude observations show the existence of a surface density of Carina-population stars which is a few percent of the central density as far as 3.5kpc away from the dS center along its major axis. These measurements support the model of Carina as a tidally disrupting galaxy with no excess dark matter.
