Symposium - International Astronomical Union, 1989 We critically review the status of our current understanding of galactic dynamo theory. In brief, a definitive model for the production of magnetic fields on galactic scales remains to be constructed.

A Long‐Lived Planetesimal Dynamo Powered by Core Crystallization
Geophysical Research Letters, 2021 The existence of numerous iron meteorite groups indicates that some planetesimals underwent melting that led to metal‐silicate segregation, sometimes producing metallic cores.

General Relativistic Magnetohydrodynamics Mean-Field Dynamos
Fluids, 2022 Large-scale, ordered magnetic fields in several astrophysical sources are supposed to be originated, and maintained against dissipation, by the combined amplifying action of rotation and small-scale turbulence. For instance, in the solar interior, the so-

New Journal of Physics, 2021 Reaching gigagauss magnetic fields opens new horizons both in atomic and plasma physics. At these magnetic field strengths, the electron cyclotron energy ℏω _c becomes comparable to the atomic binding energy (the Rydberg), and the cyclotron frequency ω ...

The Solar Dynamo and Planetary Dynamo [PDF]
Symposium - International Astronomical Union, 1993 A dynamo driven by flows of differential rotation and global convection in a rotating sphere is reviewed as a model of the solar and planetary dynamos. The flows can amplify a magnetic field from an infinitesimal level and thus can generate a magnetic field.

International Astronomical Union Colloquium, 1991 AbstractThe traditionalαΩ-dynamo as a model for the solar cycle has been successful in explaining the butterfly diagram, phase relations between poloidal and toroidal field, and polar branch migration features. Observational and theoretical achievements in recent years have however shaken this picture.

Dynamic Modeling of Indole Glucosinolate Hydrolysis and Its Impact on Auxin Signaling
Frontiers in Plant Science, 2018 Plants release chemicals to deter attackers. Arabidopsis thaliana relies on multiple defense compounds, including indol-3-ylmethyl glucosinolate (I3G), which upon hydrolysis initiated by myrosinase enzymes releases a multitude of bioactive compounds ...
