Modeling of Earth's Magnetosphere and other Magnetic Planets

Theoretical aspects on the interaction of solar wind with earth and other planets will be studied in detail under this programme. This study is possible by developing three dimensional magnetodydrodynamic model which can explain obstacle, shapes, sizes and extension of the tail which are generated by the strength and direction of the solar wind approaching the planets and interacting them.

Dynamics of Thermospheres of Venus, Earth and Mars

The long term objective is to compare physical and chemical processes responsible for the dynamical structures of the thermospheres of Venus, Earth and Mars. The atmospheres of these planets are driven by similar forcing agents and subsequently change over time both naturally and in the case of earth as a result of human influence.

Analytical Yield Spectrum

This approach is based on Monte Carlo method. In this method mono energetic electron of different incident energies are introduced in a gas medium. The energy of secondary or tertiary electrons and their positions were calculated at time when primary electrons ionize the atmospheric constituents. In this way, yield spectrum function was generated for the calculation of the yield of any state in the mixture of gases. The function was fitted analytically later. This approach has been found very useful for low and medium energy loss processes in planetary ionospheres.

One and Two dimensional Continuity and Momentum Equations

These models are developed in the laboratory using finite difference method and are being used in many problems of planetary atmospheres.

Three Dimensional Magnetohydrodynamic (MHD) Approach

The computer modelling of solar wind interaction with planetary magnetospheres and its assoscaited current system is now current interests of scientists throughout the globe. This study has been started by developing three dimensional MHD model which can explain obstacle, shapes, sizes and extension of the tail which are generated by strength and direction of the solar wind approaching the planet and interacting with them.

Kinetic Model

A kinetic model for polar ion exosphere of magnetic planets is developed in the laboratory to calculate escape flux and density of ions and electrons through the plasma sheet at different exospheric electron temperatures along the magnetic field lines originating from the baropause at high altitude.
