Galactic dynamo simulations
Recent simulations of supernova-driven turbulence within the ISM support the existence of a large-scale dynamo. With a growth time of about two hundred million years, the dynamo is quite fast – in contradiction to many assertions in the literature. We here present details on the scaling of the dynamo effect within the simulations and discuss global meanfield models based on the adopted turbulen...
متن کاملSolar Dynamo Theory
TheSun’smagnetic field is the engine and energy source driving all phenomena collectively defining solar activity, which in turn structures the whole heliosphere and significantly impacts Earth’s atmosphere down at least to the stratosphere. The solar magnetic field is believed to originate through the action of a hydromagnetic dynamo process operating in the Sun’s interior, where the strongly ...

15 صفحه اولDirect simulations of a supernova-driven galactic dynamo
Context. Supernovae are known to be the dominant energy source for driving turbulence in the interstellar medium. Yet their effect on magnetic field amplification in spiral galaxies is still poorly understood. Analytical models based on the evolution of isolated, non-interacting supernova remnants predicted a dominant vertical pumping rendering dynamo action improbable. Aims. In the present wor...
متن کاملStatistical Physics Models of Opinion Spread: Theory and Empirical Tests
We investigate a set of discrete-spin statistical physics models for opinion spread in social networks and explore how suitable they are for predicting real-world belief change on both the individual and group levels. Our studies center on the degree and rate of consensus formation in inhomogeneous models that take into account different individual preferences or set beliefs. We investigate the...
