Young Stellar Populations in the Collisional Ring Galaxy NGC 922
Young Stellar Populations in the Collisional Ring Galaxy NGC 922
We studied the star cluster population properties in the nearby collisional ring galaxy NGC 922 using HST/WFPC2 photometry and population synthesis modeling. We found that 69% of the detected clusters are younger than 7 Myr, and that most of them are located in the ring or along the bar, consistent …
