TY - CONF T1 - Are counter-rotating jets possible? Y1 - 2013 A1 - Vlahakis, N. A1 - Sauty, C. A1 - Cayatte, V. A1 - Matsakos, T. A1 - Tsinganos, K. A1 - Lima, J. AB - Young stellar object observations suggest that some jets rotate in the opposite direction with respect to their disk. In a recent study, we have shown that this can be well in agreement with the magnetocentrifugal mechanism that is believed to launch such outflows. Here, we extend this analytical derivation to relativistic jets demonstrating that under rather general conditions counterrotation can indeed take place. We also illustrate the involved mechanism by performing relativistic magnetohydrodynamic jet simulations.
