TR Jets above Magnetic X-Type Null Points

Various chromosphere and transition region jet-like structures aboundplaying an essential role in the dynamics and evolution therein. Tentatively identifyingthe wave characteristics and oscillatory behavior in the outer solar atmosphere helps tounderstand this layer better. In addition to the whip-like behavior, null-point motions in thereconnection site can excite transversal oscillation along the magnetical dense Jets,which is called the kink mode wave, and also this mode can evolve into Alfven waveafter its propagation into the more homogeneous medium. The study of X-ray jets isan important topic in understanding the heating of the solar corona and the origin ofthe fast wind. The recently launched Hinode mission permitted us to observe the excellentproxies of these jets with an unprecedented high spatial resolution of 120 km on theSun. We selected a high cadence sequence of SOT (Hinode) observations taken withboth the HCaII and the Halpha filter to look at the details of the dynamics revealedby a significant jet event. Both wavelet and amplitude spectra analysis were used toanalyze the observed kink wave and the time variations of intensities during the event.The results are discussed in the frame of different models implying reconnections withthe inference of the dynamical phenomena occurring near several null points, includingthe oscillatory behavior.
