Ionized gas in active molecular cloud cores.
Abstract
The star-forming regions NGC 2071, CRL 961, S106 IR, and S87, contain compact continuum radio sources. It is hypothesized that powerful stellar winds generate the radio emission in S106 IR and CRL 961, in view of their miniscule 5-GHz angular size, strong 4.05 micron Br-alpha H-recombination line, and proximity to the centers of expanding molecular or ionized gas. All of the objects studied are sufficiently hot and active to produce ionizing radiation and/or powerful stellar winds. The disruption of the star-forming molecular cloud is in progress. The direct observation of high velocity molecular and ionized gas shows that energetic mass outflow is a major process associated with the birth and early life of the stars studied.
