Short-Period Comets: Origin and Terrestrial Impact Hazard . ... The model is consistent with the basic observed distributions of near-parabolic comets, short-period comets, Centaurs and high-eccentricity trans-Neptunian objects.This model requires that initial objects in the early Solar System are concentrated to the outer planetary region, and the physical lifetime of comets in the inner planetary region at the present epoch is an increasing function of initial perihelion distances. ...

In the regular experiments carried out with the RAS radio telescopes at Pushchino during 1999-2002, the study of the radial dependence of scattering of compact natural radio sources was extended to remote regions of the solar plasma environment. ... The stream in the transalfvenic region displays the same typical radial structure as observed in the transonic region, i.e., the existence of a "precursor" - a narrow band of reduced scattering preceding a wide region of enhanced scattering. ...
