The Clusters AgeS Experiment (CASE). Variable stars in the field of the open cluster NGC 6253
J. Kaluzny, M. Rozyczka, W. Pych +1
The field of the metal-rich open cluster NGC 6253 has been surveyed in a search for variable stars. A total of 25 new variables were detected, 14 of which are bright stars with 13<…
The Clusters AgeS Experiment (CASE). VI. Analysis of two detached eclipsing binaries in the Globular Cluster M55
J. Kaluzny, I. B. Thompson, A. Dotter +4
We present an analysis of the detached eclipsing binaries V44 and V54 belonging to the globular cluster M55. For V54 we obtain the following absolute parameters: $M_p=0.726\pm 0.01…
The Clusters AgeS Experiment (CASE): Variable Stars in the Globular Cluster 47 Tucanae
J. Kaluzny, M. Rozyczka, W. Pych +3
Based on over 5400 BV images of 47 Tuc collected between 1998 and 2010 we obtained light curves of 65 variables, 21 of which are newly detected objects. New variables are located m…
Absolute parameters of AE For -- a highly active detached binary of late K type
M. Rozyczka, P. Pietrukowicz, J. Kaluzny +3
We present photometric and spectroscopic analysis of AE For -- a detached eclipsing binary composed of two late K dwarfs. The masses of the components are found to be 0.6314 +- 0.0…
A New Lower Main Sequence Eclipsing Binary with Detached Components
M. Rozyczka, J. Kaluzny, P. Pietrukowicz +4
We present an analysis of NGC2204-S892 -- a new detached eclipsing binary composed of two late K dwarfs. Based on three photometric campaigns launched in 2008 we obtained 5 light c…
Radial Velocity Studies of Close Binary Stars. IX
Wojtek Pych, Slavek M. Rucinski, Heide DeBond +8
Radial-velocity measurements and sine-curve fits to the orbital velocity variations are presented for the eighth set of ten close binary systems: AB And, V402 Aur, V445 Cep, V2082…
