Fredagskollokvium: THE UBIQUITOUS SOLAR MAGNETIC FLUX EMERGENCE PROCESS

 The process of magnetic flux emergence happens continuously and everywhere over the solar surface. Hence the
ubiquitousness. No matter which spatial scale we look at (granular, supergranular, active region)
buoyant magnetic field coming from the convection zone pierces the photosphere in the form of two opposite
polarities. We will describe the general characteristics of magnetic flux emergence at different spatial scales from an
observational point of view. But we will also have a look at how numerical simulations can help us
understanding the whole process. And why do we care? Rumours say that flux emergence at different scales maybe
one of the prime contributors to the heating of the upper layers of the Sun, so maybe it's worth having a look!
