How to look into the Solar interiorMoscow, Russia (SPX) Mar 27, 2014 An international group including one professor from the Moscow State University proposed the first ever quantitative description of the mechanism responsible for sunspot formation and underlying the Solar activity cycle. Magnetic field helicity is one of the so-called motion invariants in magneto-hydrodynamics. It is a conserved quantity, like energy, describing the degree to which the field lines are "wrapped around themselves". During the last 20 years, scientists realized that conservation of t ... read more |
