โฆ Synopsis
Using a simplified form of the bremsstrahlung cross-section, we obtain an analytic expression for the intensity of electron-beam-produced hard X-ray emission with depth in solar flares. The results show that 'footpoint' emission is more likely than previously thought, and we discuss these results in the light of recent observations. * Presidential Young Investigator.

I have studied the observational relationship between the location of flare sites in active regions and three other observables, viz., Ha line width, hard X-ray burst parameters, and peak microwave fluxes. Results suggest that the strength of the magnetic field plays a role in governing the magnitud
The problem of producing the hard X-ray burst at the onset of solar flares may be thought of in terms of the problem of producing the non-thermal electrons which emit the X-rays via bremsstrahlung. Electron acceleration to relativistic energies without similar ion acceleration is difficult to achiev
