Asymptotic Giant Branch Variables in NGC 6822
Published online by Cambridge University Press: 05 December 2011
Abstract
Multi-epoch JHKS photometry is used to identify large amplitude variables and to study the AGB population of NGC 6822. 50 Mira variables, ranging in period from 128 to 998 days, have been identified. The majority of these are around 1 to 4 Gyr old, but a significantly younger component is also identified.
