Comet Nucleus: Some Characteristics and a Hypothesis on Origin and Structure,mets. These points will be followed by presentation of the problem of cosmic ray irradiation of comets in the long time they survive in the Oort Cloud. A more detailed discussion of this phenomenon, including an experimental investigation of ice irradiation by 1 MV proton, will be given by Marla Moo

Ultraviolet Spectroscopy of Comets,l as several simple molecules made from these species have their strong resonance transitions in the ultraviolet region of the spectrum. However, due to the opacity of the atmosphere to ultraviolet, these observations must be made from space, and it was not until 1970 that the extensive HI Lyman α e

Interplanetary Dust - Its Physical Nature and Entry into the Atmosphere of Terrestrial Planets,k, fine grained material similar to carbonaceous chondrites but different from known meteorites in mineralogy and structure. If the analyzed samples are typical interplanetary particles then they are probably cometary materials similar to the vast numbers of cometary particles which have continuousl

Chemical Kinetics IM the Coma,are described and correlated to distance in the coma above the nucleus and to heliocentric distance of the comet. Two classes for the composition of comets are considered based on their place of origin: in the environs of the giant planets or in a companion fragment of the presolar nebula. Compariso
