Deep VLA images of LS I +61 303: a search for associated extended radio emission.

Abstract (from CDS):

Deep VLA observations at 6 cm of the field around the radio emitting X-ray binary LS I +61 303 have been carried out in an attempt to search for associated extended radio emission. The angular scales explored go from the arcsecond to the arcminute range. Only clumps of extended radio emission within a few arcminutes of the source are detected. However, in contrast with other X-ray binaries with associated extended radio emission, all these clumps seem to be unrelated to LS I +61 303 itself. The fact that some of them are positionally coincident with optical nebulosities in the field strongly suggests an interpretation based on free-free radio emitting material from the nearby HII region W4. The possibility that an undetected radio jet is present in LS I +61 303 is also discussed.
