Journal of Geophysical Research: Space Physics, 1994
Immediately after the flybys at comet Halley by a fleet of spacecraft in 1986, Gringauz et al. (1986a) reported the detection by the Vega‐ 2 spacecraft of a chemical and sharp plasma boundary, which they named the “cometopause,” at a distance of ∼1.6 × 105 km from the nucleus.

Halley's Comet

Annual Review of Earth and Planetary Sciences, 1982
Since 240 B.C., Chinese observers have documented a nearly unbroken record of scientifically useful observations of Periodic Comet Halley (P/Halley). Investigations of the comet's motion by Western astronomers are discussed, taking into account the first successful prediction of a cometary return by Halley (1705), computations conducted by Rosenberger (

Halley’s Comet

2008
At its 1986 apparition, Halley’s Comet became by far the most studied comet in history with five space probes encountering it and a multitude of ground based telescopes observations carried out by both amature and professional astronomers. In this overview we will discuss only the part of the data set that is of most interest ot infrared astromers ...
