Gravitational instability of filamentary molecular clouds, including ambipolar diffusion; Non-isothermal filament
Mohammad Hosseinirad, Shahram Abbassi, Mahmood Roshan +1
Recent observations of the filamentary molecular clouds show that their properties deviate from the isothermal equation of state. Theoretical investigations proposed that the logat…
The effects of toroidal magnetic field on the vertical structure of hot accretion flows
Fatemeh Zahra Zeraatgari, Amin Mosallanezhad, Shahram Abbassi +1
We solved the set of two-dimensional magnetohydrodynamic (MHD) equations for optically thin black hole accretion flows incorporating toroidal component of magnetic field. Following…
Anchoring polar magnetic field in a stationary thick accretion disk
Maryam Samadi, Shahram Abbassi
We investigate the properties of a hot accretion flow bathed in a poloidal magnetic field. We consider an axisymmetric viscous resistive flow in the steady state configuration. We…
Self-Gravity in Magnetized Neutrino-Dominated Accretion Discs
Narjes Shahamat, Shahram Abbassi
What is conducted in the present work is the study of self-gravity effects on vertical structure of magnetized neutrino-dominated accretion disc (termed NDAF and considered as a ce…
The Kelvin-Helmholtz instability in the Orion nebula: The effect of radiation pressure
Akram Yaghouti, Mohsen Nejad-Asghar, Shahram Abbassi
The recent observations of rippled structures on the surface of the Orion molecular cloud (Berné et al. 2010), have been attributed to the Kelvin-Helmholtz (KH) instability. The wa…
The influence of outflow and global magnetic field on the structure and spectrum of resistive CDAFs
Maryam Ghasemnezhad, Shahram Abbassi
We examine the effects of a global magnetic field and outflow on radiatively inefficient accretion flow (RIAF) in the presence of magnetic resistivity. We find a self-similar solut…
