TitleInternal stellar kinematics of three dwarf ellipticals in the Local Group.
AuthorsBender, R.; Paquet, A.; Nieto, J. -L.
AbstractRotation curves for the stellar bodies of three low surface- brightness dwarf ellipticals in the Local Group are presented (NGC 147, NGC 185, NGC 205). NGC 147 rotates with 6.5 +/- 2 km/s and has a mean velocity dispersion of 23 +/- 5 km/s between 20 arcsec and 100 arcsec; this galaxy is the faintest one for which a well sampled stellar rotation curve has been measured so far. NGC 185 and NGC 205 show no significant ...
