Radial variations of flow parameters and composition of cold heavy ions within 50,000 KM of Halley's nucleus
Abstract
Composition and flow parameters of cold heavy ions from the PICCA instrument are presented within a cometocentric distance of 50,000 km. A distinct boundary at ≡27,000 km, where the flow parameters changed abruptly, is identified and its physical significance is discussed. Radial profiles of various heavy ion groups and abundance ratios are given.
