Morphology of early-type galaxies in compact groups. IV. Rose groups.

Abstract (from CDS):
In the previous papers of this series (Bettoni & Fasano
1993AJ....105.1291B,
1995AJ....109...32B and Fasano & Bettoni
1994AJ....107.1649F) we presented data relative to early-type galaxies in several Hickson (
1982ApJ...255..382H; catalog
VII/85) and Shakhbazyan (1973-1979) Compact Groups. In this paper we present, for the first time, data on early-type galaxies belonging to 9 Rose (
1977ApJ...211..311R) compact groups. The selection criteria of these groups make them more compact than the Hickson and Shakhbazyan groups and, for this reason, the Rose groups constitute a good sample for testing the properties of early-type galaxies in environments of extreme (at least apparent) density. Even if the present sample is not a sizeable one (18 objects), we find that morphological and photometric properties of E and S0 galaxies in the Rose groups are fairly consistent with those of galaxies in the Hickson and Shakhbazyan samples. In particular, there is a lack of very flat objects in the ellipticity distribution.
