Abstract
A photometric investigation of the association Car OB 2 was carried out with a photoelectric standard sequence observed with the ESO photometric telescope and plates taken with the ADH telescope of Boyden Observatory. The distance of Car OB 2 is 2.04 kpc, the color excess E B-V is 0m.38. The main sequence of this ‘OB’ association reaches at least to late A-type stars. The luminosity function was determined and compared with the luminosity functions of very young open clusters observed by Walker (1957). The distance of a group of 13 early-type stars in the area of Car OB 2 (‘group c’) was found to be 2.5 kpc, the reddening Om.68. The relation of Car OB 2 and group c to the structure of the Carina arm is regarded.
