Abstract

As a part of the project for The Atlas of (d-C) Diagams of Eclipsing Binaries, a total of 1822 times of minimum lights for Algol distributed from 1782 to 1988 are collecte dand analyzed to investigate the period-changes of the system. An (0-C) diagram constructed shows that the orbital period of Algol has varied in complicated ways. In this paper, we would interprets these variations as the sudden changes of the periodrather than as a somewhat periodic ones. The importancy of the observations for the times of minimum lights of Algol system will be stressed.
