Abstract: 
In a cold plasma approximation the excitation of electromagnetic and electrostatic waves by anisotropic electrons is considered. It was shown that whistlers are excited in the coronae of the Sun and stars most effectively. Results of this work may be used for the flare plasma diagnostics.
Keywords: cold plasma, flare plasma diagnostics, Sun's corona
