Benjamin Gidron,Yeheskel Hasenfeldcometary nuclei are described and commented upon. With three exceptions, all hypotheses conclude or imply that a single compact object forms. It has been almost universally assumed that grain accretion produced compact aggregates as is the case with liquid drops, and that this process continued. Sev

Secondly, theories on the origin of comets—theories based upon the chemical composition of the volatile component of cometary matter—ar

A Review of Radio Interferometric Imaging of Cometsortant, and that for Comet Wilson, outgassing from cometesimals ejected from the nucleus may be significant. We further show that asymmetric line profiles are more common than previously thought. Lengthening integration times and lowering the velocity resolution results in a smooth, round shape for

Irradiation Effects on Comets and Cometary Debrisnt applications of laboratory results are reviewed. In particular, the ability of ion irradiation of simple carbon-containing ices to produce complex refractory organic materials is discussed. In the Oort cloud, this process can occur several meters into the surface, so that the buildup of a stable
