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…

Isochrone fitting of Galactic globular clusters -- IV. NGC6362 and NGC6723

George A. Gontcharov, Maxim Yu. Khovritchev, Aleksandr V. Mosenkov +10

We present new isochrone fits to the colour-magnitude diagrams of the Galactic globular clusters NGC\,6362 and NGC\,6723. We utilize 22 and 26 photometric filters for NGC\,6362 and…

Δμ Binaries among Stars with Large Proper Motions

M. Yu. Khovritchev, A. M. Kulikova

Based on observations performed with the Pulkovo normal astrograph in 2008-2015 and data from sky surveys (DSS, 2MASS, SDSS DR12, WISE), we have investigated the motions of 1308 st…
