The Star Formation Regions SNO 76 and RCW 105
Two star formation regions in the southern sky are discussed. The first of these, SNO 76, consists of stars that form a trapezium system, along with IR stars and stars with dust envelopes. One of these stars is associated with a cometary nebula. This star is a variable with an amplitude of 3m.77. This system is associated with the point IR source IRAS 10138-6004. 12CO(1-0) observations of the molecular cloud associated with this star formation region reveal the presence of red and blue outflows. The second star formation region, RCW 105, consists of two groups of stars together with stars on bright filaments. These stars include IR stars and stars with dust envelopes. This star formation region is embedded in a radial system of type-I dark globules that is formed by the star HD 144969. This system is not included in any of the known catalogs of radial systems.
