Spatial distribution of neutral and ionized gas in the Halley comet coma after the perihelion.
Abstract
Long slit Halley comet spectra taken at ESO Observatory after the perihelion have been analyzed. It has been shown that the comet increased its gas production rate of a factor 3 on 22.9 March 1986, then it decreased to half the 23.1 March 1986.
