The unexpected corona of v374 Peg |
|
| Current dynamo theories predict that low-mass, fully convective stars should have either small-scale fields produced by a turbulent dynamo, or a large-scale, non-axisymmetric field. The recent Zeeman-Doppler magnetic map of v374Peg (Donati et al, 2006, Science, 311,633) shows that in fact it has a strong, large scale field that is predominantly axisymmetric.
