We show that inverse Compton losses of ultrarelativistic electrons travelling upstream through the outflowing fields of a radio pulsar prevent the entry ofall cosmic ray electrons into most pulsars’ magnetospheres. We also argue that gamma ray triggering is probably not relevant, and conclude that the external triggering of electron-positron cascades proposed by Ruderman & Sutherland and by Radhakrishnan is not likely to be a major contributor to the plasma dynamics of pulsars.

Continuous Article Publishing mode
Since January 2016, the Journal of Astrophysics and Astronomy has moved to Continuous Article Publishing (CAP) mode. This means that each accepted article is being published immediately online with DOI and article citation ID with starting page number 1. Articles are also visible in Web of Science immediately. All these have helped shorten the publication time and have improved the visibility of the articles.
