A cluster of compact radio sources in NGC 2024 (Orion B).


Abstract (from CDS):

We present deep 3.6 cm radio continuum observations of the H II region NGC 2024 in Orion B obtained using the Very Large Array in its A configuration,(1) with 0".2 angular resolution. We detect a total of 25 compact radio sources in a region of 4'x4'. We discuss the nature of these sources and its relation to the infrared and X-ray objects in the region. At least two of the radio sources are obscured proplyds whose morphology can be used to restrict the location of the main ionizing source of the region. This cluster of radio sources is compared with others that have been found in regions of recent star formation.
