A Program of Ground-Based Astronomy to Complement Einstein Observations.
Abstract
The objective of the funded research is to formulate and carry out a program of ground-based astronomical observations to complement X-ray data accumulated with the Einstein Observatory, and to use the results of these multiwavelength studies in addressing a number of significant astrophysical problems of current interest. The work focuses on three main topics: quasar emission mechanisms and their evolution; the structure and evolution of supernova remnants and the neutron stars which they may contain; and, the processes leading to high energy emission in the outer atmosphere (winds, coronae, etc) of main sequence stars. The physics to be addressed ranges from the generation and energetics of neutron star particle beams and their interaction with the surrounding medium to the details of supernova shock waves and their role in cosmic ray acceleration; from the basic structure of matter at supernuclear densities in neutron star interiors to the basic structure of the Universe as revealed in the evolution of quasars; and, from the study of the radiation processes in distant active galactic nuclei to the identification of the critical parameters which determine the level of coronal activity in nearby late-type stars. A detailed progress report is contained in section C below; sections D and F list the of the research reports and papers.
