A PHOTOMETRIC STUDY FOR A CLOSE BINARY RZ Cas

A PHOTOMETRIC STUDY FOR A CLOSE BINARY RZ Cas

New UBV Photometric observations for a close binary RZ Cas were obtained at the Chungbuk National University Observatory for 42 nights from October 1991 to March 1993, and standardized UBV light curves were constructed. From the primary light curves, the eight minimum times were determined by using...

From the primary light curves, the eight minimum times were determined by using a new light element. We confirmed the primary minimum was totality and derived the average duration was 18.1 minutes corresponding to 0.P01. The photometric and spectroscopic solutions were calculated with the obtained light curves and the radial velocity curves of Duerbeck & Hanel(1979) by using Wilson-Devinney method. From these values, the absolute dimensions of this binary system were estimated.http://ocean.kisti.re.kr/downfile/volume/kosss/OJOOBS/1997/v14n2/OJOOBS_1997_v14n2_233.pdf
