ABSTRACT

The Role of Magnetic field on the structure of Advection

Dominated Accretion Flow with Wind

By

Nassim Beiranvand

The main aim of this research is studying the effect of toroidal magnetic field on the structure of Advection-

Dominated Accretion Flows (ADAF) in the presence of the turbulence viscosity and diffusivity due to viscosity

and magnetic field respectively.We use self-similar assumption in radial direction to solve the set of

magnetohydrodynamic (MHD) equations for hot accretion disk. We adopt spherical coordinate to solve

our equation. The toroidal component of magnetic field is considered and we also assumed that all three

components of the velocity field are present in our work, . Then the equations reduce to a set of

OEDs about direction. To solve them, we put our symmetric boundary condition at the equatorial plane of the

disk. Our results show that the radial velocity of the flow material will have a positive value. So according to

previous work by Jiao & Wu 2011 we can define three regions. The first is called inflow region. In this area,

velocity has a negative value which starts from midplane of the disk to a certain inclination0 where

r 0 It is

obvious that in the inflow region, the accretion material moves toward the central object. Also the region where

r 0 is called outflow region which is placed between 0 and surface of the disk,

0 ,here the

accretion flow moves away from the central object. At last by our configuration, the region between the surface

of the disk and the polar axis is called the wind region. This area is very narrow and the material is blown out

from the surface in the form of wind. In this paper we consider two parameters to show the magnetic field

effects. These parameters include ratio of gas pressure to magnetic pressure in the equatorial plane of the

disk, . and also magnetic diffusivity parameter, . Numerical calculations of our model have revealed that

the toroidal components of magnetic field has a significant effect on the vertical structure of accretion disk.

Statement of Purpose

Nassim Beiranvand Ph.D Applicant

Human has always been enchanted by the night sky. From naked eye observations to the eraof multi-

wavelength surveys each resolved problem has raised up other questions about the cosmos;Starting

by formation of stars but not ending with cluster structure, observations have tested predictions of

theoretical cosmology, refining the assumptive models. Rapid construction of large telescopes and

sophisticated astronomical detectors in the past century has facilitated astrophysicists with new tools

and accordingly, very large amount of raw data to investigate the enigmatic universe From childhood, I

had an immense avidity for astronomy. My parents used to bring me books about nature and the

universe, but my questions were never ending. In elementary school, I joined some classes in

educational Observatory where I saw and learned to use a telescope for the first time . I had the dream

to become a professional astronomer since this passionate experience.During high school I was

interested in physics and mathematics by attitude to incorporate them as new tools to different

astrophysical problems. To follow my childhood dream, I was admitted Khoramabad University

,Department of Physics ,in my home city .As I am very interested in Astrophysics I was successful the

nation-wide entrance exam for universities (‘Conquer’), and became a MSc student at Damghan

University ,Department of Astrophysics . For MSc student this is necessary to become familiar with

divergent research areas in astrophysics.Thus, I was awarded a full grant to participate Ninth

introductory astronomy course RIAAM, Research Institute for Astronomy and Astrophysics of

Maragha ,26-31, 2012, August, Maragha Iran, also I attended Fifth National Conference on Astronomy

and Astrophysics Iran ,28-29 December ,2011,Damghan Iran. This was a promising opportunity for me

to extend my expertise in theoretical and technical aspects of Astrophysics .As I was very enthusiastic

and doing a lot of work both of professional and amateurs in astronomy , I was selected to be an

Official representative of the Astronomical Society of Iran for Scientific cooperation with Armenia so I

participated the Viktor Ambartsumian International Prize in Armenia also I received grant for

participate Fourth Byurakan International Summer School (4BISS) for young astronomers September

15-23, 2012, Byurakan (Armenia).I did my MSc thesis about accretion disc around black hole under

supervision Dr.Shahram abbassi .I joined his group at IPM Institute for Research in Fundamental

Sciences (IPM1) School of Astronomy and started research The main aim of this research is studying

the effect of toroidal magnetic field on the structure of Advection-Dominated Accretion Flows (ADAF)

in the presence of the turbulence viscosity and diffusivity due to viscosity and magnetic field

respectively.We use self-similar assumption in radial direction to solve the set of

magnetohydrodynamic (MHD) equations for hot accretion disk. We adopt spherical coordinate(r,θ,φ)

to solve our equation. The toroidal component of magnetic field is considered and we also assumed

that all three components of the velocity field are present in our work,(ϑ_r ,ϑ_θ,ϑ_φ) . Then the

equations reduce to a set of OEDs about direction. To solve them, we put our symmetric boundary

condition at the equatorial plane of the disk. Our results show that the radial velocity of the flow

material will have a positive value. So according to previous work by Jiao & Wu we can define three

regions. The first is called inflow region. In this area, velocity has a negative value which starts from

midplane of the disk to a certain inclination where It is obvious that in the inflow region, the accretion

material moves toward the central object. Also the region where ,is called outflow region which is

placed between and surface of the disk, <θ<θ_s,here the accretion flow moves away from the central

object. At last by our configuration, the region between the surface of the disk and the polar axis is

called the wind region. This area is very narrow and the material is blown out from the surface in the

form of wind. In this paper we consider two parameters to show the magnetic field effects. These

parameters include ratio of gas pressure to magnetic pressure in the equatorial plane of the disk,β_0.

and also magnetic diffusivity parameter, η_0 . Numerical calculations of our model have revealed that

the toroidal components of magnetic field has a significant effect on the vertical structure of accretion

disk.the result of this work has been published in Monthly Notices of the Royal Astronomical Society

Main Journal.
