摘要：

Coude IIaO plates of thirty-five southern K-M giants and supergiants were obtained in the H and K lines of CaII using the 1.6 m telescope of the Laboratorio Nacional de Astrofisica (LNA, Brazil). CaII K line intensity varies with temperature in a similar way as do transition region lines and coronal X-ray emission. This indicates that magnetic heating plays a certain role in the heating of the outer layers of late-type stars.
