[PPS04-06] Solar chromospheric dynamics by ALMA observations
Keywords:The Sun, ALMA, radio astronomy, chromosphere
In this talk, we would like to describe the solar observations by using ALMA in Cycle-4 and hopefully the preliminary results from the observations. Among them, our team proposed an observation of chromospheric spicules; the needle-like jets ubiquitously found in the chromosphere, though their driving mechanism is still under debate. By the three-dimensional radiative MHD simulations, Iijima (2016) found that an untwisting motion of magnetic flux bundle could be a good candidate, which mechanism is a similar one to the astronomical jet from a accretion disk.
