Inferences on Coronal Magnetic Fields from SOHO UVCS Observations
Romoli, M.; Wu, S. T.; Poletto, G. +2 more
The characteristics of the magnetic field ubiquitously permeating the coronal plasma are still largely unknown. In this paper we analyze some aspects of coronal physics, related to the magnetic field behavior, which forthcoming SOHO UVCS observations can help better understand. To this end, three coronal structures will be examined: streamers, cor…
Oblique Emission of Whistler-Mode Waves around Interplanetary Shocks
Balogh, A.; Forsyth, R. J.; Scime, E. E. +4 more
We present a study of whistler-mode wave generation and wave particle interaction in the vicinity of interplanetary shocks as observed by the Ulysses spacecraft. Generally the whistler-mode waves (measured in the frequency range 0.22-448 Hz) are observed downstream of the shocks where they persist for some hours. From the electron distribution fun…
