Abstract

THE AIM OF THIS PAPER IS TO INVESTIGAT THE ROLE OF MAGNETIC DIFFUSIVITY PARAMETER ON THE STRUCTURE OF ADAFS. WE USE THE SELF-SIMILAR ASSUMPTION IN RADIAL DIRECTION TO SOLVE THE MHD EQUATIONS FOR HOT ACCRETION DISKS. THE TOROIDAL COMPONENT OF MAGNETIC FIELD AND ALL THREE COMPONENTS OF THE VELOCITY FIELD N º (N𝑟, NQ, NJ) ARE CONSIDERED IN OUR WORK. OUR RESULTS INDICATE THAT THE OUTFLOW REGION, WHERE THE REDIAL VELOCITY BECOMES POSITIVE IN A CERTAIN INCLINATION ANGLE Q0, ALWAYS EXISTS. WE SEE THAT THE STRONGER MAGNETIC DIFFUSIVITY PARAMETER DOES NOT HAVE ANY SENSIBLE EFFECT ON THE INCLINATION ANGLE, Q0. NUMERICAL CALCULATIONS OF OUR MODEL HAVE REVEALED THAT THE MAGNETIC DIFFUSIVITY PARAMETER HAS A SIGNIFICANT EFFECT ON THE VERTICAL STRUCTURE OF ACCRETION DISKS.
