摘要:ABSTRACT(#br)We examine the effects of a hydrodynamical wind on advection‐dominated accretion flows (ADAFs) with thermal conduction in the presence of a toroidal magnetic field under a self‐similar treatment. The disc gas is assumed to be isothermal. For a steady state struc...

摘要:ABSTRACT(#br)The combined impact of rotation and magnetic fields on oscillations of stellar fluids is still not well known theoretically. It mixes Alfvén and inertial waves. Neutron stars are a place where both effects may be at work. We aim to solve this problem in the cont...

摘要:ABSTRACT(#br)We examine the effect of self‐gravity in a rotating thick‐disc equilibrium in the presence of a dipolar magnetic field. First, we find a self‐similar solution for non‐self‐gravitating discs. The solution that we have found shows that the pressure and d...

摘要:Abstract(#br)Force due to the self-gravity of the disc in the vertical direction is considered to study its possible effects on the structure of a magnetized advection-dominated accretion disc. We present steady-sate self similar solutions for the dynamical structure of such a ty...

摘要:Abstract(#br)we examine the effect of thermal conduction on the observational properties of a super critical hot magnetized flow. We obtained self-similar solution of a magnetized disc when the thermal conduction plays an important role. Follow of our first paper (Ghasemnezhad et...

摘要:Aims. We investigate the $\beta$ -prescription forviscosity in standard self-gravitating thin disks and predict thatin a self-gravitating thin disk the $\beta$ -model will have adifferent dynamical behavior compared to the well-known $\alpha$ -prescription. Methods. W...
