Abstract:
Results of CCD observations of 154 double or multiple stars, made with
the 2 m telescope of the Bulgarian National Astronomical Observatory
at Rozhen over five nights in 2015, are presented. This is the ninth
series of measurements of CCD frames obtained at Rozhen. We also
present results of CCD observations of 323 double or multiple stars
made with the 0.6 m telescope of the Serbian Astronomical Station on
the mountain of Vidojevica over 23 nights in 2015. This is the fourth
series of measurements of CCD frames obtained at this station. This
paper contains the results for the position angle and angular
separation for 801 pairs and residuals for 127 pairs with published
orbital elements or linear solutions. The angular separations are in
the range from 1.52" to 201.56", with a median angular separation of
8.26". We also present eight pairs that are measured for the first
time and linear elements for five pairs.
Description:
This is the ninth series of CCD observations of double and multiple stars,
obtained at the Bulgarian National Astronomical Observatory at Rozhen
(NAOR) over five nights. As previously, the CCD camera VersArray 1300B
was used, which was attached to the 2 m telescope. For each double or
multiple star, five CCD frames in the Johnson B filter and five frames
in the Johnson V filter were taken, which enabled us to determine the
magnitude difference for these filters.
In 2015 at the Astronomical Station at Vidojevica (ASV), over a total
of 23 nights, observations were carried out by using the 60 cm telescope
with a Cassegrain optical system. This is the fourth observational series
at ASV since the work started there in 2011. In the observations we
used the Apogee Alta U42 CCD camera whose characteristics can be found
in the paper by Cvetkovic et al. (2016, J/AJ/151/58). Every pair was
observed five times in the Cousins/Bessel B filter and five times in
the Cousins/Bessel V one.

Note (1): The position angle has not been corrected for precession and it is
thus based on the equinox for the epoch of observation.
Note (2): Between the components of pairs determined using IRAF. In some cases
the images of stars were obtained with too few counts in either or
both filters so that we could not determine the magnitude difference.
