Abstract: In the last few years, solar jets have appeared as a potential source for the switchbacks event that are observed in the inner heliosphere by Parker Solar Probe and Solar Orbiter. Touresse et al., 24 have recently shown that the propagating non-linear Alfvénic wave associated with the generation of solar jet does produce the typical in-situ switchback signatures, i.e. an Alfvénic deflection of the magnetic field. Numerous questions remain about the parameter range of validity of the simulations of Touresse et al. 24. Does a smaller sized source active region induced smaller-sized deflection? Does the size has an impact on the maximum deflection amplitude angle? To which extent the magnetic geometry of the source region plays a role in shaping the propagating deflection, and modifying the switchback signature? To address these questions, building on the set-up of Touresse et al. 24, we carry new 3D MHD simulations in a spherical wedge of the propagation of a self-induced coronal jet, using the Adaptive Refined MHD Solver (ARMS) code. Early results from these new parametric simulations are presented in this poster.
