Some Unsolved Problems in Astrophysics
Abstract
The theoretical and observational situation with regard to solar neutrinos is reviewed and some of the implications of the discrepancy between theory and observation are discussed. A definition is suggested for compact luminous objects (CLO's) and various proposals for the energy source of CLO's are reviewed. The observational situation and opportunities with regard to the association of CLO's (or QSO's) with galaxies is outlined. The absorption lines observed in large-redshift CLO's are divided tentatively into two classes whose origin is discussed. A number of critical observations are suggested to test various unorthodox ideas.
