On the interaction of jets with stellar winds in massive x-ray binaries

摘要

We present the first three-dimensional simulations of the evolution of a microquasar jet inside the binary star system. The aim is to study the interaction of these jets with the stellar wind from a massive companion and the possible locations of high-energy emission sites. We have simulated two jets with different injection power in order to give a hint on the minimum power required for the jet to escape the system and become visible in larger scales. In the setup, we include a massive star wind filling the grid through which the jet evolves. We show that jets should have powers of the order of 10 ~(37) erg s~(-1) or more in order not to be destroyed by the stellar wind. The jetwind interaction results in regions in which high-energy emission could be produced. These results imply the possible existence of a population of X-ray binaries undetected in the radio band due to jet disruption inside the region dominated by the stellar wind.
