Planetary magnetic fields are important indicators of planetary processes and evolution,
from a planet's outer core to its surface (if it possesses one) to its atmosphere and near …

Aims. We aim to increase the sample of ultracool dwarfs studied in the radio domain to allow
a more statistically significant understanding of the physical conditions associated with these …

We have observed six late L and T dwarfs with the Karl G. Jansky Very Large Array (VLA) to
investigate the presence of highly circularly polarized radio emission, associated with large …

Ultracool dwarfs (UCDs) are a category of astronomical objects that includes brown dwarfs
and very-low-mass stars. Radio observations of UCDs have measured their brightness as a …

Stellar coronal activity has been shown to persist into the low-mass star regime, down to late
M-dwarf spectral types. However, there is now an accumulation of evidence suggesting that …

ABSTRACT A number of ultracool dwarfs emit circularly polarized radio waves generated by
the electron cyclotron maser instability. In the solar system such radio is emitted from regions …

We aim to advance our understanding of magnetic activity and the underlying dynamo
mechanism at the end of the main sequence. To this end, we have embarked on collecting …

Auroral radio emissions in planetary magnetospheres typically feature highly polarized,
intense radio bursts, usually attributed to electron cyclotron maser emission from energetic …

Radio observations of stars trace the plasma conditions and magnetic field properties of
stellar magnetospheres and coronae. Depending on the plasma conditions at the emitter …

As part of a wider search for radio emission from nearby systems known or suspected to
contain extrasolar planets, epsilon Eridani was observed by the Jansky Very Large Array …
