摘要：

We have analysed eclipse data on Z Cha over the period 1972-81, and have found that the times of white dwarf eclipse can no longer be represented by a linear ephemeris. A quadratic fit to the data implies an evolution time-scale P/P˙ = 9.6 × 106 yr. © 1981 Royal Astronomical Society. Provided by the NASA Astrophysics Data System.
