Extract

The fast-approaching return of Halley's comet in early 1986 has awakened fresh interest in comets and their role in the origin and evolution of the solar system. Some 2 years ago I suggested (Prentice 1983a, referred to as P83a) that the Sun may possess at its centre a comet-like core of mass about 1%M⊙ which had accreted from a swarm of grains and cometesimals which once occupied the interstellar cloud fragment from which the Sun had formed. The existence of such a central chemical inhomogeneity leads to a new class of evolved solar models which have a neutrino capture rate of 2.1 SNU, in line with the Davis experiment (Cleveland et al. 1981).
