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…
Photometry and Spectroscopy of Eclipsing Binaries in omega Centauri
J. Kaluzny, I. Thompson, W. Krzeminski +3
Detached eclipsing double line spectroscopic binaries are accurate distance indicators. They can be used for the direct determination of distances to globular clusters in which suc…
RR Lyrae Variables in the Globular Cluster M5
J. Kaluzny, A. Olech, I. Thompson +3
We present V-band CCD photometry of 65 RR Lyr variables from the globular cluster M5. We have estimated the basic physical parameters for 16 RRc stars and 26 RRab stars using a Fou…
A photometric survey for variable stars in the globular cluster M5
J. Kaluzny, I. Thompson, W. Krzeminski +1
We present the results of a photometric survey for variable stars in the nearby globular cluster M5. A 14.8x22.8 arcmin^2 field centered on the cluster was monitored for a total of…
Discovery of 5 Minutes Sine-like Oscillations in the light curve of the Asteroid 1689 Floris-Jan
W. Pych
We present CCD photometry of the long period asteroid 1689 Floris-Jan. On the light curve from nights 1997.02.10/11 and 1997.02.11/12 we detected sine-like oscillations with the pe…
CCD Photometry of Dwarf Nova AL Com in Superoutburst
W. Pych, A. Olech
We report a CCD optical photometry of a dwarf nova AL Com in superoutburst. Before superhumps occurred the light curve was highly variable with dominant periods about 41 minutes an…
