Optically thick super-Eddington winds in Galactic superluminal sources Academic Article uri icon


  • A model of major ejection events in Galactic superluminal sources GROJ 1655-40 and GRS 1915-105 is proposed, in which episodes of e-e+pair creation give rise to the formation of optically thick outflows accelerating protons to the limiting Lorentz factor of order 2-3. Probable source of e-e+pairs is pion production in nucleon collisions. Subsequent deceleration of ejecta and formation of radio jets is analyzed in detail within a shock deceleration model. The detailed data available for GRO J 1655-40 are shown to be in good agreement with proposed scenario.
