PLASMA FLOWS AND THEIR PHYSICAL IMPLICATIONS IN THE SUN’S ATMOSPHERE

Abstract

The presence of flows carries a basic signature of any dynamic system, and it provides the clue to unraveling the ongoing physical processes there. Therefore, the study of flows is of universal importance, which holds the key to the inference of physical parameters and underlying physical conditions in any dynamic scenario either in day-to-day life such as different kinds of machines and technology, or planetary, interplanetary, solar and stellar atmospheres, laboratory and cosmic plasmas. The 99.9% of the matter in the universe remains in the plasma state, where the flows at diverse spatio-temporal scales constitute multitude of dynamics and energetic processes. A few novel examples at the larger dimensions are the outflows from the star forming regions, flows of the solar and stellar winds, the accretion flows and relativistic jets associated with active galactic nuclei (AGNs), shock related flows due to supernova explosions, etc. There are many more such examples that basically constitute a variety of exotic physical processes existing in the universe. However, when we look at a more confined dimensions in space, we also find the intriguing role of the energetic plasma flows.
