Abstract
We use statistical data giving the number of stars formed as a functio n of the age, assigned using the observed deterministic relation betwe en chromospheric activity and age, to show that the temporal behaviour of star formation in the solar neighbourhood must have been chaotic d uring time intervals of less than 1 Gyr. We also offer evidence that s ystems of gas and stars typified by that in the solar vicinity show be haviour analogous to that of the logistic map.
