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…
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 photometry. We derived a reddening of ~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…
The contribution of the color space in LSST-like photometry for the selection of extragalactic globular cluster candidates
Nicholas Schweder-Souza, Ana L. Chies-Santos, Rafael S. de Souza +16
Globular clusters (GCs) are excellent tracers of their host galaxies' evolutionary histories. Traditional methods for identifying GCs in galaxies rely on cuts over photometric cata…
Hidden Figures of Globular Clusters: Integrated Stellar Populations Impacted by Hot Subdwarfs
Thayse A. Pacheco, Paula R. T. Coelho, Lucimara P. Martins +8
Globular clusters (GCs) are fundamental for understanding the integrated light of old stellar populations and galaxy assembly processes. However, the role of hot, evolved stars, su…
Stellar atmospheric parameters and chemical abundances of about 5 million stars from S-PLUS multi-band photometry
C. E. Ferreira Lopes, L. A. Gutiérrez-Soto, V. S. Ferreira Alberice +30
Context. Spectroscopic surveys like APOGEE, GALAH, and LAMOST have significantly advanced our understanding of the Milky Way by providing extensive stellar parameters and chemical…
Low surface brightness dwarf galaxies and their globular cluster populations around the low-density environment of our closest S0 NGC3115
Marco A. Canossa-Gosteinski, Ana L. Chies-Santos, Cristina Furlanetto +12
Understanding faint dwarf galaxies is fundamental to the development of a robust theory of galaxy formation on small scales. Since the discovery of a population of ultra diffuse ga…
The Fourth S-PLUS Data Release: 12-filter photometry covering square degrees in the southern hemisphere
Fabio R. Herpich, Felipe Almeida-Fernandes, Gustavo B. Oliveira Schwarz +68
The Southern Photometric Local Universe Survey (S-PLUS) is a project to map sq deg of the sky using twelve bands (seven narrow and five broadbands). Observations are per…
CCD photometry and dynamics of the open cluster NGC 1513
İnci Akkaya Oralhan, Hikmet Çakmak, Yüksel Karataş +2
We derive astrophysical parameters of the open cluster NGC 1513 by means of colour indices built with new photometry. Based on early-type members, the mean fore…
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…
J-PLUS: Identification of low-metallicity stars with artificial neural networks using SPHINX
D. D. Whitten, V. M. Placco, T. C. Beers +24
We present a new methodology for the estimation of stellar atmospheric parameters from narrow- and intermediate-band photometry of the Javalambre Photometric Local Universe Survey…
Astrophysical and Structural Parameters of the Open Clusters NGC 6866, NGC 7062, and NGC 2360
O. Gunes, Y. Karatas, C. Bonatto
We derive astrophysical and structural parameters of the poorly studied open clusters NGC 6866, NGC 7062, and NGC 2360 based on filtered 2MASS (J, J -H) diagrams, and stellar radia…
