Isochrone Fitting of Galactic Globular Clusters -- VIII. Homogeneous estimates of parameters for 27 clusters

G. A. Gontcharov, O. S. Ryutina, C. J. Bonatto +2

We use the Stetson, HST, and Gaia DR3 data sets for 22 Galactic globular clusters to select their members and fit their CMDs with isochrones from DSED and BaSTI for $[α /$ Fe $] = + 0.4$ …

CCD () photometry of the open cluster NGC 6793 and its dynamical evolution

Zahra Al, Yüksel Karataş, Raul Michel Murillo +4

We present new astrophysical parameters for the open cluster NGC~6793 based on new CCD $U B V (R I)_{K C}$ photometry. We derived a reddening of $E (B - V) = 0.24 \pm 0.02$ ~mag and a heavy…

Isochrone Fitting of Galactic Globular Clusters -- VII. NGC1904 (M79), NGC4372, and revision of NGC288, NGC362, NGC5904 (M5), NGC6205 (M13), and NGC6218 (M12)

George A. Gontcharov, Sergey S. Savchenko, Olga S. Ryutina +8

We estimate key parameters for the Galactic globular clusters NGC1904 and NGC4372 and update the parameters for NGC288, NGC362, NGC5904, NGC6205, and NGC6218, which were analysed i…
