Studio morfologico della cometa P/Swift-Tuttle durante l'apparizione del 1992.
Abstract
The study of hundreds visual, photographic and CCD observations of comet 109P/Swift-Tuttle made by amateurs and mostly published in popular magazines allowed the authors to estimate the expansion velocities of the coma and the behaviour of the plasma tail. The photometric and morphologic behaviour is accounted for by a monolithic nucleus, rotating in 2.92 d and erupting gas and dust from three restricted areas of its surface.
