Herbig-Haro flows in Ophiuchus.

PHELPS R.L. and BARSONY M.

Abstract (from CDS):

We report the results of a new [S II] and nearby off-line, narrowband continuum imaging survey of an approximately 0.5 deg2 area of the ρ Ophiuchi cloud core. Higher sensitivity and an improved pixel scale (0".37) over previous surveys has increased the inventory of Herbig-Haro (HH) flows in the cloud core. We report 11 independently discovered HH objects or newly discovered components of known HH objects. Three previous candidate HH objects have been confirmed, seven new highly probable, and an additional five possible HH object candidates have been identified. The approximate number of independently driven outflows in the ρ Ophiuchi cloud core approaches 50 when the number of HH flows detected in the present study is combined with the number of known CO outflows. The number of outflows exceeds the number of known Class I/Class 0 objects in the same area by at least a factor of 2, leading to the conclusion that Class II and Class III objects must also be outflow drivers. There is direct evidence in these data for Class II and Class III HH flow drivers, although the lack of detected emission down to the sources themselves precludes definitive identification of the great majority of the driving sources.
