Millimeter-wave interferometric study of the ρ Ophiuchi A region. I. Small-scale structures of dust continuum sources.
KAMAZAKI T., SAITO M., HIRANO N. and KAWABE R.
Abstract (from CDS):
From our CO observations, we have discovered a previously unknown CO outflow whose axis is almost parallel to that of the nearby outflow associated with VLA 1623. However, the center of this outflow is likely to be the near-infrared source GY 30, and does not coincide with any of the small fragments. All small fragments except one show no sign of protostellar activities such as CO outflow and centimeter radio continuum emission, suggesting that they are in the evolutionary stage prior to protostar formation with outflow activities. On the other hand, the small fragment with the largest mass is likely to be associated with 6 cm continuum emission, which is thought to be free-free emission. This implies the possibility that the protostellar formation has already occurred in the fragment. The presence of small-scale fragments with and without protostellar activities suggests that star formation in this region occur in such a small fragment or through coalescence of several small fragments.
