Alfvénic Motions Arising from Asymmetric Acoustic Wave Drivers in Solar Magnetic Structures

Alfv\'enic motions are ubiquitous in the solar atmosphere and their observed properties closely linked to those of photospheric p-modes. However, it is still unclear how a predominantly acoustic wave driver can produce these transverse oscillations magnetically dominated corona. In this study we conduct 3D ideal MHD numerical simulation model straight, expanding coronal loop gravitationally stratified which includes transition region chromosphere. We implement locally at one foot-point corresponding an acoustic-gravity inclined by $\theta = 15^{\circ}$ with respect vertical axis magnetic structure similar incident on loop. show that produced loop, displace waveguide due breaking azimuthal symmetry, resulting modes theoretical framework cylinder model. By conducting Fourier analysis perturbed velocity signals, contribution from different cylindrical obtained. Furthermore, vorticity computed demonstrate manifest themselves throughout whole non-uniform space. Finally present some physical perturbations amplitudes range $0.2-0.75$ km s$^{-1}$ exhibit two distinct oscillation regimes $42$ s $364$ s, where latter value close period p-mode simulation.
