Interaction of Ion Cyclotron Electromagnetic Wave with Energetic Particles in the
Existence of Alternating Electric Field Using Ring Distribution
The elements that impact the dynamics and collaborations of waves and particles
in the magnetosphere of planets have been considered here. Saturn’s internal
magnetosphere is determined by substantiated instabilities and discovered to be an
exceptional zone of wave activity. Interchanged instability is found to be one of the
responsible events in view of temperature anisotropy and energization processes of
magnetospheric species. The generated active ions alongside electrons that constitute
the populations of highly magnetized planets like Saturn’s ring electron current are
taken into consideration in the current framework. The previous and similar method of
characteristics and the perturbed distribution function have been used to derive
dispersion relation. In incorporating this investigation, the characteristics of
electromagnetic ion cyclotron wave (EMIC) waves are determined by the composition of
ions in plasmas through which the waves propagate. The effect of ring distribution
illustrates non-monotonous description on growth rate (GR) depending upon plasma
parameters picked out. Observations made by Cassini found appropriate for modern study,
have been applied to the Kronian magnetosphere. Using Maxwellian ring distribution
function of ions and detailed mathematical formulation, an expression for dispersion
relation as well as GR and real frequency (RF) are evaluated. Analysis of plasma
parameters shows that, proliferating EMIC waves are not developed much when propagation
is parallelly aligned with magnetosphere as compared to waves propagating in oblique
direction. GR for the oblique case, is influenced by temperature anisotropy as well as
by alternating current (AC) frequency, whereas it is much affected only by AC frequency
for parallel propagating waves.
期刊介绍:
JASS aims for the promotion of global awareness and understanding of space science and related applications. Unlike other journals that focus either on space science or on space technologies, it intends to bridge the two communities of space science and technologies, by providing opportunities to exchange ideas and viewpoints in a single journal. Topics suitable for publication in JASS include researches in the following fields: space astronomy, solar physics, magnetospheric and ionospheric physics, cosmic ray, space weather, and planetary sciences; space instrumentation, satellite dynamics, geodesy, spacecraft control, and spacecraft navigation. However, the topics covered by JASS are not restricted to those mentioned above as the journal also encourages submission of research results in all other branches related to space science and technologies. Even though JASS was established on the heritage and achievements of the Korean space science community, it is now open to the worldwide community, while maintaining a high standard as a leading international journal. Hence, it solicits papers from the international community with a vision of global collaboration in the fields of space science and technologies.
