Description
We perform radiation magneto-hydrodynamic simulations of the solar atmosphere, driven self consistently by sub-surface convection, thereby producing a forest of spicules commensurate with the observed properties (Dey et al, 2022, Nat Phys). By varying the strength of the imposed magnetic field (mimicking the dynamo generated large scale field of the Sun), we show that kinematic properties of the spicules (e.g., height, acceleration) depend on the properties of the magnetic environment. We also present the analysis to understand the physics behind such dependence on the magnetic field (Kesri et al, 2024, ApJ) and coronal temperature.
