Evidence for or against a common origin of hard X-rays and microwaves from solar flares
- 23 Downloads
The problem of whether hard X-rays and microwaves are emitted from the same electrons in common or closely separated sources is reviewed on direct and indirect observational evidence. Detailed analyses of time structure and peak flux suggest that hard X-rays and microwaves are emitted from nearly co-spatial sources due to electrons streaming down to the chromosphere. However this model has not been confirmed yet by direct imaging observations.
