SOME RESULTS OF THE U CrB OBSERVATIONS IN 1856 - 2007

Odessa Astronomical Publications, 2017
Historical results over of photometry of eclipsing variable star U CrB (type of EA / SD) are brought after 1856 - 2007. Authors suppose that in the system U CrB there is a trade-out by a substance between components.

Investigating Stellar Variability in the Open Cluster Region NGC 381

The Astronomical Journal, 2023
We study variable stars in the field of the open cluster NGC 381 using photometric data observed over 27 nights and identify a total of 57 variable stars, six of which are member stars. The variable stars are classified based on their periods, amplitudes,

Proper identification of RR Lyrae Stars brighter than 12.5 mag [PDF]

, 2005
RR Lyrae stars are of great importance for investigations of Galactic structure. However, a complete compendium of all RR-Lyraes in the solar neighbourhood with accurate classifications and coordinates does not exist to this day.

Detection of Variable Stars in the Open Cluster M11 Using Difference Image Analysis Pipeline [PDF]

Journal of Astronomy and Space Sciences, 2010
We developed a photometric pipeline to be used for a wide field survey. This pipeline employs the difference image analysis (DIA) method appropriate for the photometry of star dense field such as the Galactic bulge.
