Magnetoacoustic Heating of the Solar Chromosphere
In the present work we wish to examine the viability of the acoustic waves generated in the solar convection zone propagating radially outward through the overlying atmosphere and getting resonantly absorbed by the magnetic arches of the low-lying chromospheric canopy. We demonstrate that the resultant Poynting and acoustic flux that enters the magnetic canopy in the network regions is adequate to explain the energy losses from the chromospheric layer of the sun.
