The turbulent state of cometary ion pickup generated fluctuations near comet P/Halley

Krauklis, I.; Johnstone, A. D.

One of the principal effects of an outgassing comet is to introduce additional mass into the solar wind flow. This mass-loading process results in the generation of Alfvén waves via ion-cyclotron resonance. In the case of the Halley encounter this source of ``new'' fluctuations was introduced into a low speed solar wind 0.89 AU from the sun. Previ…
