1995AJ....110.1664F THE YOUNG GLOBULAR CLUSTERS OF THE MILKY WAY AND THE LOCAL GROUP GALAXIES: PLAYING WITH GREAT CIRCLES F. FUSI PECCI Osservatorio Astronomico, V. Zamboni 33, I-40126, Bologna, Italy Electronic mail: 37929::flavio,ilavio@astl:o3.bo.astro.it M. BELLAZINI Dipartimento di Astrononiia, V. Zamboni 33, I-40126, Bologna, Italy C. CACCIARI AND F. R. FERRARO Osservatorio Astronomico, V. Zamboni 33, I-40126, Bologna, Italy Received 1994 December 14; revised 1995 May 18 ABSTRACT The small group of galactic globular clusters (GGC) (Pal 12, Terzan 7, Ruprecht 106, Arp 2) recently discovered to be significantly younger (by ~3-4 Gyr) than the average cluster population of the Galaxy are shown to lie near planes passing in the vicinity of some satellite galaxies of the Milky Way and through the galactic center itself. Assuming that these configurations represent a fossil record of interactions between the Galaxy and its companions from which these clusters originated, we identified, along one of them, another candidate "young" GGC, i.e., IC 4499, whose color-magnitude diagram is presented. Various hypotheses on the possible origin of "young" GGC are also briefly discussed within a framework where the location on preferential planes may be seen as a general characteristic for the Local Group members.
