LkHa101, an extreme emission line star with a disk and illuminating an HII region

We present new results on LkHa101 based on the mid-infrared imaging with FORCAST on SOFIA, CARMA 3 mm imaging, IRTF SpeX medium resolution spectra from 0.8 - 5 micron, and Herschel PACS archive data. These observations, combined with published VLA data eveal that LkHa 101 is still surrounded by a face-on photo-evaporating accretion disk and is illuminating an HII region. The accretion disk is hot T > 1000 K) and mostly ionized. The FORCAST, PACS and CARMA CO(1-0) and 13CO(1-0) images show a strong interaction between the dense molecular cloud north of LkHa101 and the expanding HII region, but no interaction with the cold foreground cloud providing most of the extinction toward the star.
