Continuous solutions of cosmic-rays and waves in astrophysical environments
(UMT, Lahore, 2023) Kinza Irshad
The interaction of cosmic rays with thermal plasma in the presence of magneic field have great importance in Astrophysical environment. The interaction of different components available in intersteller medium are not yet completely understood. From the last few decades, this problem becomes important when we discuss the interaction of cosmic rays with plasma in space, such as interstellar clouds. We consider our system as a four-fluid system in which we have thermal plasma, cosmic rays, and two opposite propagating Alfvén waves. We investigate the dynamics and different energy exchange mechanisms of the system. We study the importance of different pressure gradients and their impact on feedback in astrophysical environments. Additionally, cosmic rays diffusion within the plasma is considered along the field lines
