| Abstract: |
Acoustic wave dissipation is a viable mechanism for the heating of chromospheres and coronae. In absence of magnetic fields in the center of supergranulation cells on the sun and on very slowly rotating stars the acoustic heating mechanism appears to dominate. In the solar chromospheric network and on moderately or rapidly rotating stars acoustic heating is a weak background effect. The theoretical limiting shock strength behavior and the direct solar observation of acoustic waves are both consistent with the empirical chromospheric energy requirements of the sun. |
