Magnetic field propagation in a stellar dynamo
Journal of Statistical Physics, 1985Numerical 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), 2014The 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.

Calibration on the sun for stellar magnetic fields
2008The intimate association between the surface magnetic fields and the Ca II K line emission known to exist on the sun, holds a promise for using this property to detect the presence of global magnetic fields on sun - like stars. We have obtained a large number of K line profiles over a variety of plages on the sun and related the 1A emission flux ...

Stellar Magnetic Fields: Measurements and Diagnostics
1988Magnetic fields are central to our understanding of surface activity in cool stars. This paper reviews recent progresses in the measurements of photospheric magnetic fields and stresses some of the main difficulties in the analysis of magnetic field observations.
