Modeling Jupiter's Synchrotron Emission from Relativistic Electron Trapped in Jovian Magnetosphere

Abstract

Shubha Singh, A. K. Singh and R.P. Singh

The relativistic electron energy in few MeV range, trapped in the Jovian magnetosphere emit electromagnetic waves in wide radio frequency domain which escapes the generation region and propagates towards the Earth’s atmosphere. The flux density of the emission is a function of the electron distribution (spatial and angular), the energy spectrum of the electron, the magnetic field strength and configuration. The measured spectral power density of high energetic electrons and its distribution with frequency can be used to find out the distribution of relativistic electrons in the inner magnetosphere having the range LJ =3 Jovian radius. In present communication the variation of radiated power per electron with energy through the synchrotron radiation process have been shown and discussed. The simulated flux density is compared with corresponding recent emitted radio spectrum data available from Cassinni flyby. The investigation enables us to explain the mechanism and characteristic properties of Jovian magnetosphere.
