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 photometric and Gaia astrometric study of eight open clusters- ASCC 115, Collinder 421, NGC 6793, NGC 7031, NGC 7039, NGC 7086, Roslund 1 and Stock 21
T. Yontan, S. Bilir, Z. F. Bostanci +8
In this study, we carried out CCD UBV photometry of eight open clusters, ASCC 115, Collinder 421, NGC 6793, NGC 7031, NGC 7039, NGC 7086, Roslund 1, Stock 21, and determined their…
CCD UBV photometric study of five open clusters - Dolidze 36, NGC 6728, NGC 6800, NGC 7209 and Platais 1
Z. F. Bostanci, T. Yontan, S. Bilir +9
In this study, we present CCD UBV photometry of poorly studied open star clusters, Dolidze 36, NGC 6728, NGC 6800, NGC 7209, and Platais 1, located in the first and second Galactic…
Metallicity Calibration and Photometric Parallax Estimation: I. UBV photometry
S. Tuncel Guctekin, S. Bilir, S. Karaali +3
We present metallicity and photometric parallax calibrations for the F and G type dwarfs with photometric, astrometric and spectroscopic data. The sample consists of 168 dwarf star…
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…
