A statistical study of hard X-ray directivity in flares View all project descriptions by submitter

Gordon Emslie Submitted: 21-Jul-2003 17:54

Directivity of solar flare hard X-ray emission should manifest itself as a center-to-limb variation in spectral shape. We plan to improve upon results from the SMM and pre-SMM eras by using RHESSI data to: * better define the spectral shape (rather then a best-fit power-law through a handful of points); * locate the heliocentric longitude of the hard X-ray emission directly from RHESSI images; * use spectra from the footpoint regions alone, where the directivity is predicted to be the largest A byproduct of this work is the determination of the distribution of flare sizes, another data point for the avalanchers/nanoflarers.
