Abstract:
Using the 2m telescope of the Bulgarian National Astronomical
Observatory at Rozhen, observations of 145 double or multiple stars
were carried out during three nights on 2010 September 7-9. This is
the fifth series of measurements of CCD frames of double and multiple
stars obtained at Rozhen. In this paper, we present the results for
the position angle and angular separation for 202 pairs and residuals
for 45 pairs with published orbital elements or linear solutions.
These observations have angular separations in the range
1.150"-196.372", with a median angular separation of 57.906". Three
linear solutions are presented for the first time and three orbits are
recalculated (one pair has both a linear fit and an orbital solution).
Description:
This serie comprising observations of 145 double or multiple stars
took place on 2010 September 7-9.
