a Comprehensive Investigation of X-Ray Emission from Intermediate Mass Stars
Abstract
Although X-rays have been detected from essentially all types of stars, one portion of the X-ray H-R Diagram remains an enigma. Despite large surveys using Einstein and ROSAT, it is still not clear whether or not main sequence stars of intermediate mass (spectral types B3--A7) are intrinsic X-ray sources. Stars cooler than spectral type F0 are coronal X-ray sources and O3--B3 stars are wind X-ray sources, but are the intermediate mass stars intrinsic X-ray sources and how are they heated? We will exploit AXAF's three unique properties (high resolution imaging, high energy resolution, and high sensitivity detectors with very low background) to determine whether or not the intermediate mass stars are intrinsic X-ray sources and to study the nature of the X-ray emitting plasma.
