Abstract:
We report the discovery of 19 variable stars and two blue stragglers
in the field of the open cluster NGC 6866. Three of the variable stars
we classify as delta Sct, two as g Dor, four as WUMa, two as ellipsoidal
variables, and one as an eclipsing binary. Seven stars show irregular
variability. Two of the pulsators, delta Sct star NGC 6866-29 and
gamma Dor star NGC 6866-21, are multiperiodic.
Description:
Our observations were carried out at the Bialkow Observatory of the
Wroclaw University on 14 nights between April 27 and July 21, 2007.
