uvby-β photometry of open clusters. IV. NGC 1444, NGC 1662, NGC 2129, NGC 2169, and NGC 7209.
Abstract
uvby β photoelectric photometry of the open clusters NGC 1444, NGC 1662, NGC 2129, NGC 2169, and NGC 7209 is presented. From the analysis of the data reddening, distance, temperature and gravity are determined for each star and, from the distance and reddening of each, reddening and a mean distance modulus to the clusters is assigned. Numerical value of age for each is determined through direct comparison with theoretical models. No star clustering has been found in the direction of NCC 2129.
