Isochrone fitting of Galactic globular clusters - IX. Tip of the red-giant branch for 27 clusters and constraints on new particle physics
G. A. Gontcharov, A. M. Kudashov, O. S. Ryutina +1
Red-giant evolution is sensitive to non-standard channels of energy loss in stellar cores and therefore provides a probe of new physics. Such losses increase the luminosity of the…
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 Fe…
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 -- VI. High-latitude Clusters NGC5024 (M53), NGC5053, NGC5272 (M3), NGC5466, and NGC7099 (M30)
G. A. Gontcharov, S. S. Savchenko, A. A. Marchuk +7
We fit various colour-magnitude diagrams (CMDs) of the high-latitude Galactic globular clusters NGC\,5024 (M53), NGC\,5053, NGC\,5272 (M3), NGC\,5466, and NGC\,7099 (M30) by isochr…
Isochrone fitting of Galactic globular clusters -- V. NGC6397 and NGC6809 (M55)
George A. Gontcharov, Charles J. Bonatto, Olga S. Ryutina +8
We fit various colour-magnitude diagrams (CMDs) of the Galactic globular clusters NGC\,6397 and NGC\,6809 (M55) by isochrones from the Dartmouth Stellar Evolution Database (DSED) a…
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…
