Gravitational Collapse of Magnetized Clouds I. Ideal Mhd Accretion Flow
We study the self-similar collapse of an isothermal magnetized rotating cloud in the ideal magnetohydrodynamic (MHD) regime. In the limit of small distance from the accreting protostar we find an analytic solution that corresponds to free-fall onto a central mass point. The density distribution is not spherically symmetric but depends on the mass loading of magnetic field lines, which can be ob...
متن کاملGravitational Contraction of Magnetized Clouds
In this paper, the dynamical contraction of magnetized clouds is studied from the run-away phase to the accretion phase throughout. Since the non-homologous gravitational contraction necessitates progressively ner spatial resolution, \nested grid technique" (Burger & Oliger 1984) is adopted. As a result, it is found that out ow driven by toroidal magnetic elds is occurred in the accretion phase...
متن کاملGravitational Collapse of Isothermal Magnetized Clouds: Universality of Self-similar Collapse
We study dynamical collapse of isothermal magnetized clouds with two-dimensional axisymmetric numerical simulations. As a model of the cloud, we consider an innnitely long lamentary cloud with longitudinal magnetic eld. An initial model is constructed by adding an axisymmetric perturbation on an equilibrium model. Because of gravitational instability, it fragments into magnetically supercritica...
متن کاملCollapse and Fragmentation of Magnetized Cylindrical Clouds
Gravitational collapse of the cylindrical elongated cloud is studied by numerical magnetohydrodynamical simulations. In the infinitely long cloud in hydrostatic configuration, small perturbations grow by the gravitational instability. The most unstable mode indicated by a linear perturbation theory grows selectively even from a white noise. The growth rate agrees with that calculated by the lin...
متن کاملGravitational Collapse of Magnetized Clouds Ii. the Role of Ohmic Dissipation
We formulate the problem of magnetic field dissipation during the accretion phase of low-mass star formation, and we carry out the first step of an iterative solution procedure by assuming that the gas is in free-fall along radial field lines. This so-called “kinematic approximation” ignores the back reaction of the Lorentz force on the accretion flow. In quasi steady-state, and assuming the re...
