A New Infrared Complex and Molecular Cloud in Orion
Abstract
A new complex of infrared sources 1' across has been discovered in Orion. Associated with this cluster is an extended 6' molecular cloud producing intense CO emission. Its measured infrared luminosity is less than 500 L0. The complex is hypothesized to be composed of -sequence sources. Several argnments suggest that these stars heat dust in the larger molecular cloud and thus cause the strong CO emission. The complex is not associated with a known visible or radio continuum feature, and searches over a 0?7 X 0?7 field show no other comparable unknown 2.2- sources.
