Analytical solutions for the evolution of MHD wind-driven accretion discs
Mohsen Shadmehri, Fazeleh Khajenabi
We present new analytical solutions for the evolution of protoplanetary discs (PPDs) where magnetohydrodynamic (MHD) wind-driven processes dominate. Our study uses a 1D model which…
Orbits of particles and black hole thermodynamics in a spacetime with torsion
S. Gharibi Nodijeh, S. Akhshabi, F. Khajenabi
We derive the static spherically symmetric vacuum solution for a spacetime with non-vanishing torsion by solving the field equations analytically. The effects of torsion appear as…
Properties of an accretion disc with a power-law stress-pressure relationship
Mohsen Shadmehri, Fazeleh Khajenabi, Sami Dib +1
Recent numerical simulations of magnetized accretion discs show that the radial-azimuthal component of the stress tensor due to the magnetorotational instability (MRI) is well repr…
On the dynamics of pebbles in protoplanetary disks with magnetically-driven winds
Mohsen Shadmehri, Fazeleh Khajenabi, Martin E. Pessah
We present an analytical model to investigate the production of pebbles and their radial transport through a protoplanetary disk (PPD) with magnetically driven winds. While most of…
Structure of Protoplanetary Discs with Magnetically-driven Winds
Fazeleh Khajenabi, Mohsen Shadmehri, Martin E. Pessah +1
We present a new set of analytical solutions to model the steady state structure of a protoplanetary disc with a magnetically-driven wind. Our model implements a parametrization of…
Inflation by spin and torsion in Poincare gauge theory of gravity
Siamak Akhshabi, Elham Qorani, Fazeleh Khajenabi
In Poincare gauge theory of gravity, in addition to mass-energy content, spin is also a source for gravitational interactions. Although the effects of spin are negligible at low en…
