Plasma flow inside Comet P/Halley

Johnstone, A.; Amata, E.; Formisano, V. +2 more

The plasma flow parameters (bulk velocity, number density, temperature) have been computed from the Giotto JPA data for the solar wind protons and for the water group cometary implanted ions. The decrease of the plasma bulk speed due to mass loading is followed from the bow shock at 1.16 x 10 to the 6th km from the nucleus down to well inside the …
