The Infrared Nucleus of the Wolf-Rayet Galaxy Henize 2-10.
Abstract
We have obtained near-infrared images and mid-infrared spectra of the starburst core of the dwarf Wolf-Rayet galaxy He 2-10. We find that the infrared continuum and emission lines are concentrated in a flattened ellipse 3-4('') or 150 pc across which may show where a recent accretion event has triggered intense star formation. The ionizing radiation from this cluster has an effective temperature of 40,000 K, corresponding to 30M_sun stars, and the starburst is 0.5-1.5 x 10(7) years old.
