The First Light Curve Analysis of HD 162905
Not Available

Three colour observations of southern red variable giant stars
UBV observations have been made of southern red variables of varioustypes over a period of two years. Accurate light curves of about 35variables have been obtained; in many cases the observations coveredmore than one cycle. It appears that the M-type SRb and Lb variablesdefine a curved strip in the (B-V)-(U-B) plane. The mean (U-B) of thevariable stars is about 0.5 mag bluer than the (U-B) of the nonvariableK-type giants. The red variables may be divided into different groups:the carbon stars and the M-type variables, of which the M-type stars areagain to be divided into three groups on the basis of their colorvariations and consequently their loops in the two-color plane.
