Cool Stars, Stellar Systems, and the Sun: Proceedings of the Fifth Cambridge Workshop on Cool Stars, Stellar Systems, and the Sun, Held in Boulder, Colorado, July 7-11, 1987 (Lecture Notes in Physics)

Recent Research On The Solar-stellar System Has Been Triggered By A Host Of Recent Observational Data, In Particular From Space Based Observations. For This Conference The Major Topics Selected Centered On New Measurement Capabilities (magnetic Fields And Infrared, With Specific Emphasis On The New Iras Results), Important Classes Of Stars (f Stars, M Dwarfs And Giants, And Pre-main Sequence Stars), And Interesting Unanswered Questions (the Nature Of Nonthermal Phenomena, Heating Processes, Angular Momentum Evolution, And The Existence And Cause Of The Corona/wind Dividing Line). Each Section Is Opened By Two Or More Invited Lectures Aimed At A Wide Audience, Including Graduate Students, And Continues With Some Research Papers. The Proceedings Also Record The Two General Discussions On The Role Of Magnetic Fields In Cool Star Atmospheres And The Role Of Monitoring Programs For Studies Of Cool Stars (see Also Lecture Notes In Physics Vol. 292). Contents: Stellar Magnetic Fields -- Nonthermal Phenomena In Stellar Coronae -- Heating Of Stellar Chromospheres And Coronae -- The Angular Momentum History Of Stars -- Stars With Thin And Thick Convective Zones -- Re-examining The Corona/wind Dividing Line -- Exploiting The Infrared -- Activity In Pre-main Sequence Stars -- Panel On Monitoring Programs -- Contributed Papers On Active Binary Stars -- Author Index.
