Energetic Particles in the Heliosphere

Beschreibung

This monograph traces the development of our understanding of how and where energetic particles are accelerated in the heliosphere and how they may reach the Earth. Detailed data sets are presented which address these topics. The bulk of the observations are from spacecraft in or near the ecliptic plane. It is timely to present this subject now that Voyager-1 has entered the true interstellar medium. Since it seems unlikely that there will be a follow-on to the Voyager programme any time soon, the data we already have regarding the outer heliosphere are not going to be enhanced for at least 40 years.

Presents of energetic particle data from near Earth to beyond the heliosphere into the interstellar medium Shows that the proton energy spectrum in the heliosphere is such that a significant dose would be experienced by astronauts going to Mars Provides evidence of at least three separate acceleration mechanisms for energetic particles and shows that significant acceleration is taking place around the termination shock to produce the anomalous cosmic rays Explains that measurement of the energy spectrum and anisotropy of energetic particles is crucial for understanding how the particles are accelerated and transported within the heliosphere

“The book provides an excellent overview of our current knowledge of energetic charged particles in heliosphere. It brings out the complexity of these data and highlights the challenges that we face when interpreting these data against our still-limited theoretical understanding of how the heliosphere work.” (Mike Hapgood, The Observatory, April, 2018)
