Self-Similar Solutions of Viscous-Resistive ADAFs With Poloidal Magnetic Fields
We carry out the self-similar solutions of viscous-resistive accretion flows around a magnetized compact object. We consider an axisymmetric, rotating, isotheral steady accretion flow which contains a poloidal magnetic field of the central star. The dominant mechanism of energy dissipation is assumed to be the turbulence viscosity and magnetic diffusivity due to magnetic field of the central st...
متن کاملAccretion Discs with Strong Toroidal Magnetic Fields
Simulations and analytic arguments suggest that the turbulence driven by magnetorotational instability (MRI) in accretion discs can amplify the toroidal (azimuthal) component of the magnetic field to a point at which magnetic pressure exceeds the combined gas + radiation pressure in the disc. Arguing from the recent analysis by Pessah and Psaltis, and other MRI results in the literature, we con...
متن کاملThe Effects of Thermal Conduction on the ADAF with a Toroidal Magnetic Field
The observation of the hot gas surrounding Sgr A∗ and a few other nearby galactic nuclei imply that electron and proton mean free paths are comparable to the gas capture radius. So, the hot accretion flows is likely to proceed under week-collision conditions. Hence, thermal conduction has been suggested as a possible mechanism by which the sufficient extra heating is provided in hot ADAF accret...
متن کاملSelf-Similar Vector Fields
We propose statistically self-similar and rotation-invariant models for vector fields, study some of the more significant properties of these models, and suggest algorithms and methods for reconstructing vector fields from numerical observations, using the same notions of self-similarity and invariance that give rise to our stochastic models. We illustrate the efficacy of the proposed schemes b...
متن کاملNonaxisymmetric instabilities of neutron star with toroidal magnetic fields
Aims. Super magnetized neutron stars of ∼1015 G, magnetars, and magnetized protoneutron stars born after the magnetically-driven supernovae are likely to have very strong toroidal magnetic fields. Methods. Long-term, three-dimensional general relativistic magnetohydrodynamic simulations were performed to prepare isentropic neutron stars with toroidal magnetic fields in equilibrium as initial co...
