摘要
The light curve and period variation of the eclipsing system V471 Tau is discussed. The migration period of 191 days obtained recently by Ibanoǧlu agrees well with the new observations. The period decreases by about one second per century, which may correspond to a mass transfer of 1×10 -7 solar mass. Furthermore, the O-C diagram shows a noticeable sine curve super-imposed on the parabolic variation. The period of the sine curve is about 3.1 years. © 1979 D. Reidel Publishing Co.
