CCD photometry of distant open clusters NGC 2425, Haffner 10 and Czernik 29
P. Pietrukowicz, J. Kaluzny, W. Krzeminski
We present BVI photometry for poorly known southern hemisphere open clusters: NGC 2425, Haffner 10 and Czernik 29. We have calculated the density profile and established the number…
Cluster AgeS Experiment (CASE): Dwarf Novae and a Probable Microlensing Event in the Globular Cluster M22
P. Pietrukowicz, J. Kaluzny, I. B. Thompson +4
We report the identification of a new cataclysmic variable (denoted as CV2) and a probable microlensing event in the field of the globular cluster M22. Two outbursts were observed…
