Interpretation of Fast Ripple Structure in Solar Impulsive Bursts
Abstract
The hypothesis that solar impulsive bursts are comprised of quasi-quantised ultrarapid pulses convoluted with a variable pulse repetition rate R(t) is investigated by comparison of typical observations with numerical simulations. It is found that: The ripple amplitude at burst peak increases rapidly with increase in the ratio Δ/T of pulse separation to pulse width. Consequently pulse widths T are generally much larger than the observed period Δt of small amplitude ripples.
