NGC 147, NGC 185 and CassII: a genetic approach to orbital properties, star formation and tidal debris

NGC 147, NGC 185 and Cassiopeia II (CassII) have similar positions in the sky, distances and measured line-of-sight velocities. This proximity in phase space suggests that these three satellites of M31 form a subgroup within the Local Group. Nevertheless, the differences in their star formation hist...
