Several Star-Formation Regions in the Southern Hemisphere

  • Published:
Astrophysics Aims and scope

Three new star-formation regions in the Southern Hemisphere, SFR 1, SFR 2, and SNO 28 are presented. SFR 1 is located in a dark globule with a rim, which lies in a radial system of dark globules of the first kind and represents a group of mainly IR stars, many of which are related to dust disks or envelopes. Two of the stars are related to cometary nebulae. They include Herbig-Haro objects. SFR 2 is in a dark cloud. There are stars with cometary nebulae, dust envelopes, or disks. From a star with a conical nebula a jet with a condensation is observed. SNO 28 is a star that has a dust disk with two opposite jets. One of the jets and part of the second are embedded in a dark cloud and are visible only in the IR. The outer part of the second jet emerges from the cloud and can be seen only in the visible. The second jet contains a condensation which may be a Herbig-Haro object. This object is related to the point source IRAS 08196-4931 which has IR colors typical of sources associated with water masers.
