Our program of multiwavelength observational investigations and their attendant interpretive studies concerning problems in stellar coronae, supernova, remnants, and neutron star astrophysics continued in FY 86. A variety of important projects have been undertaken, several of which reached completion in the last year of the five-year period 1 October 1981 to 30 September 1986, including the compilation of the complete X-ray flux-limited sample of M stars, a study of small scale anisotropy of the extragalactic X-ray background, and a definitive paper on the new class of composite SNRs. A total of 26 papers presenting the results of the program were published or accepted for publication in the technical literature, as well as six review articles for conference proceedings. A total of 35 presentations were given at regional, national, and international meetings by the principal investigator, two co-investigators, andor the six graduate students supported under this program. In addition, radio and optical observations under several existing proposals were conducted and more than twenty new proposals were prepared, the majority of which have already been accepted. Author
