Nonradial and nonpolytropic astrophysical outflows VIII. A GRMHD generalization for relativistic jets
Steady axisymmetric outflows originating at the hot coronal magnetosphere of a Schwarzschild black hole and surrounding accretion disk are studied in the framework of general relativistic magnetohydrodynamics (GRMHD). The assumption of meridional self-similarity is adopted for the construction of semi-analytical solutions of the GRMHD equations describing outflows close to the polar axis. In ad...
متن کاملOutflows and inflows in astrophysical systems
We seek for self-similar solutions describing the time-dependent evolution of self-gravity systems with either spherical symmetry or axisymmetric disk geometry. By assuming self-similar variable x ≡ r/at where a is isothermal sound speed we find self-similar solutions extending from the initial instant t = 0 to the final stage t → ∞ using standard semi-analytical methods. Different types of sol...
متن کاملPositive Scheme Numerical Simulation of High Mach Number Astrophysical Jets
High Mach number astrophysical jets are simulated using a positive scheme, and are compared with WENO-LF simulations. A version of the positive scheme has allowed us to simulate astrophysical jets with radiative cooling up to Mach number 270 with respect to the heavy jet gas, a factor of two times higher than the maximum Mach number attained with the WENO schemes and ten times higher than with ...
متن کاملOn the magnetic acceleration and collimation of astrophysical outflows
The axisymmetric 3-D MHD outflow of cold plasma from a magnetized and rotating astrophysical object is numerically simulated with the purpose of investigating the outflow’s magnetocentrifugal acceleration and eventual collimation. Gravity and thermal pressure are neglected while a split-monopole is used to describe the initial magnetic field configuration. It is found that the stationary final ...
متن کاملRadiation from Relativistic Strongly Magnetized Outflows
Relativistic strongly magnetized winds outflowing from fastrotating compact objects like millisecond pulsars with surface magnetic fields of ∼ 1015−1016 G are plausible sources of cosmological γ-ray bursts. In such winds, there are at least three regions where extremely powerful X-ray and γ-ray emission may be generated. The first radiating region is the wind photosphere that is at a distance o...
