PENA, J. H.; CALDERON, J. e PINA, D. S.. Study of the open cluster NGC 1528 through uvby − β photoelectric photometry. Rev. mex. astron. astrofis [online]. 2019, vol.55, n.2, pp.203-209. Epub 25-Nov-2020. ISSN 0185-1101. https://doi.org/10.22201/ia.01851101p.2019.55.02.08.
uvby − β photoelectric photometry of sixty-five stars in the direction of the open cluster NGC 1528 is presented. From the uvby − β photometry of the cluster we classified the spectral types of the stars which allowed us to determine the reddening (E(b-y) of 0.196 ± 0.054) and hence, their distance, in parsecs, of (954 ± 154). We determined membership of the stars to the cluster and the age (Log age equal 8.04) of the cluster. A metallicity [Fe/H] of −0.31 ± 0.08 was calculated.
