Title:
Auroral Radio Emission from Late L and T Dwarfs: A New Constraint on Dynamo Theory in the Substellar Regime
Abstract:
We have observed 6 late L and T dwarfs with the newly upgraded Jansky VLA to investigate the presence of quiescent or pulsed radio emission, associated with large-scale auroral currents. We present measurements of surface magnetic fields in the mid-L to late-T spectral range, providing the first firm constraints on dynamo theory in the mass gap occupied by low mass brown dwarfs.
