NASA scientists have uncovered new details about how plasma from superstorms interact with Earths magnetosphere. The surprising result of this model is that the magnetospheres main phase pressure is dominated by energetic protons from the plasmasphere, rather than from the solar wind - Mei-Ch...
Title: Close Binary Progenitors of Long Gamma Ray Bursts Authors: M.V. Barkov, S.S. Komissarov The strong dependence of the neutrino annihilation mechanism on the mass accretion rate makes it difficult to explain the LGRBs with duration in excess of 100 seconds as well as the precursors separate...
