NGC 6822: SFH of its Intermediate-Age Population
1 Université de Montréal
2 INAF, OAR
We have monitored, during four years, a 32′× 32′ area of the Local Group dwarf galaxy NGC 6822. Observations lead to the discovery of 30 Miras and 24 semi-regular and irregular variables. When relating the periods of Miras to their age, we find a continuous star formation during the last 3 Gyr. This result is basically consistent with the hypothesis that the intermediate-age population of NGC 6822 was born following the “polar ring” formation.
