Dynamics of Comets: Their Origin and Evolution

Klappentext

Proceedings of the 83rd Colloquium of the International Astronomical Union held in Rome, Italy, June 11-15, 1984

Zusammenfassung
`This collection of papers...is likely to become one of the most well-thumbed books on the bookshelf of the cometary astronomer. This is partly due to the fact that a similar volume is unlikely to appear for another decade, but more importantly because the subject matter strikes right at the heart of current cometary research - their origins and dynamics. ... recommend this work as it provides an invaluable up-to-date summary of the subject. This will be of great benefit to those already working in the field and will also serve as an excellent introduction for newcomers.'
The Observatory (August 1986)
`I can highly recommend Dynamics of Comets: Their Origin and Evolution as a source of many good discussions on this wide-ranging topic.'
