  • Oscillations of a Giant Solar Tornado 

    Hashemi-Nasab, Fatemeh؛ Dadashi, Neda؛ Alipour-Rad, Nasibeh؛ Abedini, YousefAli (Damghan University Astronomical Society of Iranدانشگاه دامغان, 2017-12-01)
    Solar magnetic tornadoes are known to be one of the mass and energy transport mechanisms from the lower solar atmosphere into the upper layers of the solar corona. A bright spiral structure with two arms is observed using ...

  • Multi fluidity and Solitary wave stability in cold quark matter: core of dense astrophysical objects 

    Ghaani, Azam؛ Eslami, Parvin؛ Sarbishaei, Mohsen؛ Javidan, Kurosh (Damghan University Astronomical Society of Iranدانشگاه دامغان, 2017-12-01)
    Considering the magneto-hydrodynamic equations in a non-relativistic multi uid framework, we study the behavior of small amplitude perturbations in cold quark matter. Magneto-hydrodynamic equations, along with a suitable ...

  • Introducing Stable Real Non-Topological Solitary Wave Solutions in 1+1 Dimensions 

    mohammadi, Mohammad؛ Olamaei, Ali Reza (Damghan University Astronomical Society of Iranدانشگاه دامغان, 2017-12-01)
    By adding a proper term to the Lagrangian density of a real non-linear KG system with a proposed non-topological unstable solitary wave solution, its stability guaranteed appreciably. This additional term in the new modified ...

  • Calculation of the relativistic bulk tensor and shear tensor of relativistic accretion flows in the Kerr metric. 

    Moeen, Mahboobe (Damghan University Astronomical Society of Iranدانشگاه دامغان, 2017-12-01)
    In this paper, we calculate the relativistic bulk tensor and shear tensor of the relativistic accretion ows in the Kerr metric, overall and without any approximation. We obtain the relations of all components of the ...
