Summary:
We propose to study the formation and impact on the solar atmosphere of so-called type II spicules using a broad range of observations that cover all temperatures between photosphere and corona, in combination with state-of-the-art radiative 3D MHD numerical simulations of a domain encompassing the convection zone through the photosphere, chromosphere into the corona. Type II spicules are the most ubiquitous jets in the solar atmosphere with the largest potential for playing a significant role in the mass and energy balance of the corona and solar wind. We will build on our recent discovery of this novel, more violent type of spicules that appear to be associated with rapid upflows with velocities of order 50-100 km/s in the lower solar atmosphere including the transition region and corona. These upflows may be the "missing link" at the heart of the solar plasma energization quandary, and are specifically called out in the description of Focused Science Topic (c) of the TR&T Announcement of Opportunity (AO). We will investigate what role the magnetic field and photospheric dynamics play in their formation, and whether these chromospheric jets play a major role in providing the corona and solar wind with hot plasma.Performance Year | Reference | Investigation Type | Actions |
