Variations in the Radio Flux of the Hypergiant P Cygni (B1 Ia+)
Abstract
The radio flux of P Cygni is variable on a time scale of months or shorter. The variations are interpreted as variations in the degree of ionization of the wind due to the ejection of shells which shield the wind from the ionizing radiation of the star. The observed time scale agrees with the recombination time scale of the wind.
