Abstract

The BVR CCD full light curves of ZZ Aur were obtained as one of the near-contact binary observing programs at the Sobaek Mt. Observatory during Feb. 2000 - Feb. 2001. From the present observations, three primary and seven secondary times of minimum light were obtained. The photometric solutions have been found using the Wilson and Divenny model.

2000년 2월부터 2001년 2월까지 소백산 천문대 61cm 망원경을 사용하여 CCD측광관측에 의한 ZZ Aur.(B, V ＆ R)의 새로운 광도곡선을 얻었다. 이와 함께 새로운 광도곡선으로 부터 주극심시각 3점과 부극심시각 7점을 얻었다. 새로운 광도곡선을 WD model에 적용하여 이 별의 궤도 요소를 구하였다
