Disks and Outflows Around Young Stars: Proceedings of a Conference Honouring Hans Elsässer Held at Heidelberg, Germany, 6–9 September 1994 (Lecture Notes in Physics)

The Subject Of The Book, The Ubiquitous Circumstellar Disks Around Very Young Stars And The Corresponding Jets Of Outflowing Matter, Has Recently Become One Of The Hottest Areas In Astrophysics. The Disks Are Thought To Be Precursors To Planetary Systems, And The Outflows Are Thought To Be A Necessary Phase In The Formation Of A Young Star, Helping The Star To Get Rid Of Angular Momentum And Energy As It Makes Its Way Onto The Main Sequence. The Possible Connections To Planetary Systems And Stellar Astrophysics Makes These Topics Especially Broad, Appealing To Generalists And Specialists Alike. The Cd Not Only Contains Papers That Could Not Be Printed In The Book But Allows The Authors To Include A Fair Amount Of Data, Often Displayed As Color Images.
