Description

Dust is widespread in the galaxy. To astronomers studying stars it may be just an irritating fog, but it is becoming widely recognized that cosmic dust plays an active role in astrochemistry. Without dust, the galaxy would have evolved differently, and planetary systems like ours would not have occurred.

To explore and consolidate this active area of research, Dust and Chemistry in Astronomy covers the role of dust in the formation of molecules in the interstellar medium, with the exception of dust in the solar system. Each chapter provides thorough coverage of our understanding of interstellar dust, particularly its interaction with interstellar gas. Aimed at postgraduate researchers, the book also serves as a thorough review of this significant area of astrophysics for practicing astronomers and graduate students.

Reviews

"I recommend this book to those who want to catch up with the latest findings about chemical reactions occurring under conditions difficult or impossible to simulate here on Earth."

-John Mathis, Science, Vol. 264, 20 May 1994

"I recommend the volume to graduate students and people entering the field."

-Il Nuovo Cimento
