Analysis of 3D plasma motions in a chromospheric jet formed due to
magnetic reconnection
Abstract
i) Within the framework of 3D resistive MHD, we simulate the formation
of a plasma jet with the morphology, upward velocity and timescale
formation similar to those expected for Type II spicules as described in
González-Avilés et al. (2018a). ii) In this paper we analyze the
transverse displacements and rotational type motion of the jet. iii) We
calculate time series of the velocity components in different points
near to the jet for various heights and find transverse oscillations in
agreement with spicule observations. iv) By analyzing temperature
isosurfaces, we find that the line-ofsight (LOS) is approximately
perpendicular to the jet axis. v) The jet shows a red-blue shift pattern
caused by rotational motion
