Compact radio sources in Orion: new detections, time variability, and objects in OMC-1S.

ZAPATA L.A., RODRIGUEZ L.F., KURTZ S.E. and O'DELL C.R.

Abstract (from CDS):

We present the analysis of four 3.6 cm radio continuum archival observations of Orion obtained using the Very Large Array in its A configuration, with 0".3 angular resolution. The observations were made during the period 1994-1997. In a region of 4'x4', we detect 77 compact radio sources. Of these sources, 54 are detected in one or more of the individual observations, and 36 of these show time variability (by more than 30%) between the observed epochs. A deep image made from averaging all data shows an additional 23 faint sources, in the range of 0.1 to 0.3 mJy. Of the 77 sources, 39 are new centimeter detections. However, only 9 of the 77 sources do not have a previously reported counterpart at near-infrared, optical, or X-ray wavelengths. In particular, we detect three faint sources in the OMC-1S region that may be related to the sources that power the multiple outflows that emanate from this part of the Orion Nebula.
