Solar Flux Emergence Simulations
We simulate the rise through the upper convection zone and emergence through the solar surface of initially uniform, untwisted, horizontal magnetic flux, with the same entropy as the nonmagnetic plasma, that is advected into a domain 48 Mm wide by 20 Mm deep. The magnetic field is advected upward by the diverging upflows and pulled down in the downdrafts, which produces a hierarchy of loop-like...
متن کاملA flux emergence model for solar eruptions
We have simulated the 3D emergence and interaction of two twisted flux tubes, which rise from the interior into the outer atmosphere of the Sun. We present evidence for the multiple formation and eruption of flux ropes inside the emerging flux systems and hot arcade-like structures in between them. Their formation is due to internal reconnection, occurring between oppositely directed, highly st...

متن کاملRadiative transfer and flux theory
The fundamental phenomenological equations of radiative transfer, e.g., Lambert's cosine rule and the radiant transport equation, are derived from an analysis based on the Cauchy flux theory of continuum mechanics. For the classical case, where the radiance is distributed regularly over the unit sphere, it is shown that Lambert's rule follows from a balance law for the transfer of radiative pow...
متن کاملThe Emergence of Optimality Theory
Generative phonology has been dominant for roughly fifty years (Chomsky & Halle 1968, etc.) with Optimality Theory (OT) being the prevailing framework in phonology for over a decade (Prince & Smolensky 2004, etc.). Both theories share the assumption that Universal Grammar (UG) provides an inventory of universal distinctive features; OT also assumes that UG provides an inventory of universal con...
