✦ Synopsis

A simple trap model of solar hard X-ray bursts is discussed in which nonthermal electrons trapped in a magnetic bottle precipitate into the lower chromosphere through the resonant scattering by whistlers. In -such a model, the X-ray spectra produced from trapped and precipitating electrons have 9 different spectral shape, and both of the spectra will initially soften with time, provided the precipitation dominates over collisional degradation.

It has been controversial whether the flare-associated hard X-ray bursts are thermal emission or non-thermal emission. Another controversial point is whether or not the associated microwave impulsive burst originates from the common electrons emitting the hard X-ray burst. It is shown in this paper
