Scientific paper

X-ray observations have shown that chromospheres, transition regions and coronae are common to stars throughout the HR diagram, and that magnetic fields play a fundamental role in the heating of outer stellar atmospheres. The observed emission levels are in both qualitative and quantitative disagreement with the predictions of the standard theory of coronal formation via the generation and dissipation of acoustic waves. As a result of recent emphasis on heating mechanisms which are based on the stressing and dissipation of magnetic fields generated by dynamo action in the subphotospheric convection zones, stellar rotation has assumed a central role in the heating problem as a controlling factor in dynamo process efficiency.
