Titolo: Unique Plasma Acceleration Process: from Aurora to Corona, from birth to death of stellar systems
Abstract: Unique auroral observations during active times indicate correlation between intense electron fluxes and oblique electromagnetic waves. This in situ result is applied to solar corona, explaining the unusual ratio of energetic He isotopes during impulsive flares together with enhanced abundances in specific heavy elements, as well as anomalous abundances in meteorites at the birth of solar system and in planetary nebulae towards the death of stellar systems.
