Abstract:
We give the results of CCD observations for 789 double or multiple stars
obtained during 2017 and 2018. These observations were carried out at both
the Serbian Astronomical Station on the mountain of Vidojevica (ASV) and
the Bulgarian National Astronomical Observatory at Rozhen (NAOR). They
were performed using three telescopes, the 1.4 and 0.6 m telescopes at ASV,
and the 2 m telescope at NAOR. The total of 1196 measurements (position
angle and angular separation) for the 939 pairs is presented. Out of this
number, 55 pairs have calculated orbital or linear elements and for them
the residuals are given. Some pairs have measurements for several epochs.
Measured angular separations are in the interval from 1.51" to 208.81",
with a median separation of 4.16". Two new pairs and linear elements for
three pairs, which are calculated for the first time, are also presented.
Description:
During 2017 at the Serbian Astronomical Station on the mountain of
Vidojevica (ASV), observations of double and multiple stars were
performed with two telescopes and three cameras. The cameras were
changed due to some problems in their work. Until June 20, the 1.4 m
telescope and CCD camera Apogee Alta U42 had been used. Due to ice
detection on the chip of this camera during its cooling the
observations were continued with the 0.6 m telescope. On this
telescope the CCD camera SBIG ST-10ME had been used until the end of
September, when the problem concerning its shutter was detected.
Because of this it was replaced by Apogee Alta E47. At NAOR the
observations were done with the 2 m telescope where, as earlier, CCD
camera VersArray 1300B was used.
In the succeeding year of 2018 at ASV the observations were performed
with CCD camera Apogee Alta U42, which in the meantime had been repaired
and mounted on the 1.4 m telescope. In the middle of 2018, because of
realuminizing the 1.4 m mirror, CCD camera Apogee Alta U42 was mounted
on the 0.6 m telescope and with that the observations continued. At NAOR
in 2018 the observations were performed with the 2 m telescope where
a new CCD camera, Andor iKon-L, was used.
All observations were made using two filters, Cousins/Bessel B and V
at ASV and Johnson B and V at NAOR.
