Magnetic field propagation in a stellar dynamo

Journal of Statistical Physics, 1985
Numerical simulations of stellar dynamos are reviewed. Dynamic dynamo models solve the nonlinear, three-dimensional, time-dependent, magnetohydrodynamic equations for the convective velocity, the thermodynamic variables, and the generated magnetic field in a rotating, spherical shell of ionized gas.

Magnetic fields in young stellar objects

2014 XXXIth URSI General Assembly and Scientific Symposium (URSI GASS), 2014
The formation of stars and planets is accompanied not only by inflows of matter, as one might expect, but also by outflows. These outflows take the form of supersonic and highly collimated jets that can stretch for several light years and extend even beyond the parent molecular cloud.

Observing and Modelling Stellar Magnetic Fields

EAS Publications Series, 2009
We start by looking at some recent developments in field measurements in middle main sequence and pre-main sequence stars. Then we consider how other magnetic effects such as the Hanle effect and continuum polarisation may be used to detect fields in a variety of stellar environments such as the solar corona and white dwarf atmospheres.

Magnetic Fields and Stellar Surface Structures

2006
We discuss the use of high-resolution spectroscopy for studying inhomogeneities on stellar surfaces. Examples of such inhomogeneities include chemical and temperature spots, pulsation waves and magnetic fields. Presence of surface structures reflects important physical processes occurring in much deeper layers than can be observed and, therefore, they ...
