A Study of Open Clusters Frolov 1 and NGC 7510 using CCD UBV Photometry and Gaia DR2 Astrometry

T. Yontan, S. Bilir, T. Ak +6

We present reddening, photometric metallicity, age and distance estimates for the Frolov 1 and NGC 7510 open clusters based on CCD UBV photometric and Gaia data. Photometric observ…

Metallicity and absolute magnitude calibrations for F-G type main-sequence stars in the Gaia era

M. Celebi, S. Bilir, S. Ak +3

In this study, photometric metallicity and absolute magnitude calibrations were derived using F-G spectral type main-sequence stars in the Solar neighbourhood with precise spectros…

CCD UBV photometry of the open cluster NGC 6819

T. Ak, Z. F. Bostanci, T. Yontan +5

We present the results of CCD UBV observations of the open cluster NGC 6819. We calculated the stellar density profile in the cluster's field to determine the structural parameters…
