Photometric monitoring of halo C stars

Listed in IVOA Registry (Virtual Observatory)

Carbon stars are among the brightest intermediate-age stars.

Description

They are seen in nearly all galaxies of the Local Group. In the Milky Way they are members of the thin disk but over a hundred have been identified in the Galactic halo.

Since the halo consists essentially of an old stellar population, these carbon stars warrant special attention. We believe that such stars are trespassers and belong to streams left over by disrupted dwarf spheroidal galaxies. By performing photometric monitoring we intend to identify Miras among the halo carbon stars.

We obtained, over several semesters, K and J images centered on the carbon stars in order to determine their variation and periodicity.
