Abstract:
A search of emission stars has been done on the basis of digitized
photographic plates received with the 40" Schmidt telescope of
Byurakan Observatory equipped with a 4° objective prism. Forty-six
new emission stars are found in a small area around the known FU Ori
type variable V733 Cep. Emission stars on the J-H - H-K diagram
are situated on or in the neighborhood of T Tau locus. V, R, I
photometry for some of the emission stars is performed as well. Three
new variable stars are found in the region. A rapid brightness
variation is detected on V733 Cep.
Description:
The observations were carried out with the 2.6m telescope of the
Byurakan Observatory from 1 to 4 December 2008.
