Three HH objects associated with jets

Abstract

Three HH objects are associated with molecular clouds. Observations of these clouds show that a molecular outflow exists in both clouds, with the bluer outflow near HH 188 coinciding in direction with an optical (visible) jet, while the the red outflow near HH 83 is opposite to this jet. One of the molecular clouds is rotating. All three objects are associated with IRAS point sources and with IR stars, one of which has the IR colors of a YSO (young stellar object). There is an IR star with two nebulae in the form of half-rings near one of the objects (HH 83).
