International Astronomical Union Colloquium, 1974
AbstractA Monte Carlo study is described that leads to an understanding of the evolution of comets, particularly how the short-period comets can arise. Some results have appeared in the March 1972 issue of Astrophysical Letters, Vol. 10, pages 131–135 (Paper I), but further results are presented here for the first time.This is a report of a particular ...

Comets and the Origin of Life

1981
The possible role of comets in the origin of life is reviewed both con and pro. The former viewpoint stresses our considerable ignorance of the physical and chemical state of comets. The latter position points out the possibility in some comets of an extended thermal history, which might have led to the production of biologically significant ...

An Interstellar Origin for Comets

1982
It is usually supposed that the outer regions of the Oort cloud have been thermalised by the cumulative effect of stellar encounters and that the long-period comets are perturbed into the inner solar system by passing stars. This heating, or relaxation, is a gentle process, Weissman (1980) for example estimating that only ∿ 9% of the primordial comet ...
