dc.description.abstract A sample of K stars has been taken from several objective-prism plates. This sample will be studied photometrically to answer two basic questions. First, is it feasible to subclassify these stars as K1, K2, K3, ... etc., which reflect temperature differences? This has been done by determining color indices of the stars in the sample and taking an average color index for stars in each subclass. Standard deviations were used to ascertain if differences between the means are statistically significant. Second, are there any red giant stars in our sample? If so, is giant contamination related to temperature classification? The B-V and V-I color indices for the program stars were compared to those of known dwarf and giant stars in a two-color diagram. The results of this study will permit more informed decisions about the value of spectral classes for K stars. Also distances (photometric parallaxes) were computed from the photometric data obtained.
