A study of some stars in the region of the open cluster NGC 3532 and the regions of five Loden cluster candidates in theer southern Milky Way.
Abstract
In total 42 stars have been photoelectrically observed in UBV and/or uvby and Hβ, and classified on objective prism spectral plates and individual spectrophotometric distances have been calculated. The main part of the stars have been selected in the regions of five Lodén cluster candidates from Centaurus to Norma, but 16 are situated in the southern part of the open cluster NGC 3532 (in Carina). Three of the cluster candidates are probably real clusters, two of them making up the same cluster. The distance modulus and colour excess of the clusters observed are (with standard deviations): V-MV = 8m .38 ± 0m.51 and EB-V = 0m.10 ± 0m.04 for NGC 3532, V-MV = 10m.58 ± 0m.27 and EB-V = 0m.21 ± 0m.04 for Lodén 442, and finally, V-MV = 12m.391 ± 0m.40 and EB-V = 0m.271 ± 0m.04 for Lodén 462-465.
