The Effects of Thermal Conduction on the ADAF with a Toroidal Magnetic Field
S. Abbassi, J. Ghanbari, S. Najjar
The observation of the hot gas surrounding Sgr and a few other nearby galactic nuclei imply that electron and proton mean free paths are comparable to the gas capture radius.…
An Accretion-Disc Model for the Algol-Type Eclipsing Binary System AV Del
Sayyed Mohammad Reza Ghoreyshi, Jamshid Ghanbari, Fatemeh Salehi
This study inspects the light and radial-velocity curves of the eclipsing binary AV Del. In comparison with other studies already done, the study shows that the absolute elements,…
Self-Similar Solutions of Viscous-Resistive ADAFs With Poloidal Magnetic Fields
J. Ghanbari, F. Salehi, S. Abbassi
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 f…
Self-Similar Evolutionary Solutions of Self-Gravitating, Polytropic -Viscous Disks
Shahram Abbassi, Jamshid Ghanbari, Fatemeh Salehi
We carry out the effect of -prescription for viscosity which introduced by Duschel et al. 2000 & Hure, Richard & Zhan 2001, in a standard self-gravitating thin disks. We were pr…
Formation of Small-Scale Condensations in the Molecular Clouds via Thermal Instability
Mohsen Nejad-Asghar, Jamshid Ghanbari
A systematic study of the linear thermal instability of a self-gravitating magnetic molecular cloud is carried out for the case when the unperturbed background is subject to local…
Linear Thermal Instability and Fluctuations in Molecular Clouds
Mohsen Nejad-Asghar, Jamshid Ghanbari
Evidence of small-scale condensations in the magnetic molecular clouds has been accumulating over the past decades through radio and optical/ultraviolet observations. The origin an…
