Exploratory C star search in the disk of M 31 beyond 30 kpc.

BATTINELLI P. and DEMERS S.

Abstract (from CDS):

In order to investigate how far the intermediate-age population of the disk of M 31 extends we survey 450-arcmin² along its southern major axis, from 35kpc to 43kpc. We identified a handful of C stars. We conclude that we have reached the edge of the M 31 disk, at least as defined by intermediate age stars. There is no evidence of density enhancement AGB stars related to the Ferguson clump possibly associated with cluster G1. Radial velocity measures could provide confirmation that the most remote C star, at 40kpc, is indeed a member of the disk population of M 31.
