Trends in Ultracool Dwarf Magnetism. II. The Inverse Correlation Between X-ray Activity and Rotation as Evidence for a Bimodal Dynamo
B. A. Cook, P. K. G. Williams, E. Berger
Observations of magnetic activity indicators in solar-type stars exhibit a relationship with rotation with an increase until a "saturation" level and a moderate decrease in activit…

Trends in Ultracool Dwarf Magnetism. I. X-Ray Suppression and Radio Enhancement
P. K. G. Williams, B. A. Cook, E. Berger
Although ultracool dwarfs (UCDs) are now known to generate and dissipate strong magnetic fields, a clear understanding of the underlying dynamo is still lacking. We have performed…
