[128.19] Formation and Evolution of Super Star Clusters in the Nearby Starburst IC 4662

We present near-IR, mid-IR, and radio observations of the central starburst regions in the nearby, irregular, metal-poor galaxy IC 4662. By combining Spitzer imaging and spectroscopy with radio maps, ground-based 10 micron images, and ground-based near-IR integral field spectroscopy, we construct SEDs of the embedded ultradense HII regions (UDHIIs) where super star clusters (SSCs) form. We fit these SEDs with models to determine the physical parameters of the UDHIIs and their dust cocoons. We also investigate the ages, stellar populations, and extinctions of more evolved and less embedded SSCs, the distribution and excitation properties of the nebular gas, and ultimately the recent star-formation and cluster-evolution history of the galaxy.
