Abstract:
We present photometric, astrometric, and kinematic studies of the old
open star clusters NGC 1193 and NGC 1798. 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.
Description:
CCD UBVRI images of the open clusters NGC 1193 and NGC 1798 and
standard stars selected from Landolt (2009, Cat. J/AJ/137/4186) were
acquired on 2013 September 19 and 2009 November 1 using a 84-cm
Ritchey-Chretien telescope T100) located at the San Pedro Martir
Observatory, Mexico.
