Abstract:
We present the results of CCD photometry in the seven-color Vilnius
system for 302 stars in the 12x12 arcmin area in the vicinity of the
dark cloud TGU H942 P7. Observational data were obtained in 2015-2016
with the 1.8m VATT telescope of the Vatican observatory on Mt Graham,
Arizona. Using the Koenig & Leisawitz (2014ApJ...791..131K 2014ApJ...791..131K)
classification scheme we identified 88 YSOs in this area. The majority
of them are concentrated in dust clump P7 and the infrared cluster FSR
655. The other compact group of YSOs is located at RA=03:54:56,
DEC=+53:45. These stars are probably members of small infrared cluster
which we call SCB1.
Description:
Table 1 contains the results of photometry of 302 stars down to
V=19.5mag in the Vilnius seven-color system in the vicinity of the
dark cloud TGU H942 P7 and emission nebula Sh2-205. Photometric data
are used to classify stars in spectral and luminosity classes. The
identification numbers, coordinates, V magnitudes and six color
indices in the Vilnius system, photometric two-dimensional spectral
types (spectral and luminosity classes) are given. The identification
numbers start from from 1001 to avoid confusion with the catalog of
Cepas et al. (2013BaltA..22..243C 2013BaltA..22..243C, Cat. J/BaltA/22/223). The
coordinates are from PPMXL catalog (Roeser et al. 2010AJ....139.2440R 2010AJ....139.2440R,
Cat. I/317).
Table 2 contains the list of 88 YSOs, identified using the Koenig &
Leisawitz (2014ApJ...791..131K 2014ApJ...791..131K) classification scheme, which combines
the WISE and 2MASS near- and mid-infrared colours. The identification
number and W1, W2, W3, J, H, Ks magnitudes are from WISE All-sky Data
Release (Cutri et al., 2012yCat.2311....0C 2012yCat.2311....0C, Cat. II/311). The types of
identified YSOs are given.
