Team reveals how current sheets in turbulent plasma form in Earth"s magnetosheath
Magnetic reconnection is a fundamental physical process in plasmas, through which the magnetic energy is converted into plasma kinetic energy and thermal energy rapidly. Current sheets in turbulent plasma are the key trigger for magnetic reconnection.....»»
Quasi-periodic eruptions from eRO-QPE2 are remarkably stable, study finds
An international team of astronomers has inspected long-term evolution of quasi-periodic eruptions (QPEs) from a QPE source designated eRO-QPE2. The study found that QPEs from this source are remarkably stable over the investigated period of over thr.....»»
