Algol型 食變光星 EE Pegasi의 光電測光觀測 = Photoelectric Observation of Algol Type Eclipsing Variable EE Pegasi

다국어 초록 (Multilingual Abstract)

Using 40㎝ reflector of the Kyungpook National University Observatory, the B and V observations of the Algol type eclipsing variable EE Pegasi were made on 11 days during the period from September 24, 1983 to October 30, 1984.
The light curves in yellow and blue lights were made with a total of 918 individual observation points. From the times of minima obtained by others so far and the one determined in this study, new light elements are deduced as follows; Min I =JD 2445994.911+2.6282131E.
The light curves obtained in this study show two unequal minima: The primary minimum with a depth of about 0.6 magnitude is an annular ecipse which lasts about O^p. 006. And the secondary minimum with a depth of about 0.1 magnitude is a total eclipse. The midsecondary eclipse occurs at the phase 0.5 and the width of the two minima are almost the same.
By comparing the present result with that by Ebbighausen(1971), it is concluded that the orbital period of EE Pegasi has been decresed.
