Opis

This volume, together with its two companion volumes, originated in a study commis- sioned by the United States National Academy of Sciences on behalf of the National Aeronautics and Space Administration. This volume is devoted to 'The Solar Interior', except that the volume begins with one chapter reviewing the contents of all three volumes.
