Both of the clusters are investigated by combining data sets from Gaia Early Data Release 3 (EDR3) and CCD UBV observational data. E(B - V ) color excesses are derived for NGC 1193 as 0.150 ± 0.037 and for NGC 1798 as 0.505 ± 0.100 mag through the use of two-color diagrams. Photometric metallicities are also determined from two-color diagrams with the results of Fe/H = -0.30 ± 0.06 dex for NGC 1193 and Fe/H = -0.20 ± 0.07 dex for NGC 1798. The isochrone fitting distance and age of NGC 1193 are 5562 ± 381 pc and 4.6 ± 1 Gyr, respectively. For NGC 1798, these parameters are 4451 ± 728 pc and 1.3 ± 0.2 Gyr. Kinematic and dynamic orbital calculations indicate that NGC 1193 and NGC 1798 belong to the thick-disk and thin-disk populations, respectively. 2022 artículo científico 0185-1101 https://www.redalyc.org/articulo.oa?id=57175502014 https://www.redalyc.org/journal/571/57175502014/ https://www.redalyc.org/journal/571/57175502014/html/ https://www.redalyc.org/journal/571/57175502014/57175502014.epub https://www.redalyc.org/journal/571/57175502014/movil 10.22201/ia.01851101p.2022.58.02.14 en http://www.redalyc.org/revista.oa?id=571 Revista Mexicana de Astronomía y Astrofísica application/pdf Universidad Nacional Autónoma de México Revista Mexicana de Astronomía y Astrofísica (México) Num.2 Vol.58 |
