Magnetospherically driven optical and radio aurorae at the end of the stellar main sequence
G. Hallinan, S. P. Littlefair, G. Cotter +12
Aurorae are detected from all the magnetized planets in our Solar System, including Earth. They are powered by magnetospheric current systems that lead to the precipitation of ener…
Periodic Optical Variability of Radio Detected Ultracool Dwarfs
Leon K. Harding, Gregg Hallinan, Richard P. Boyle +5
A fraction of very low mass stars and brown dwarfs are known to be radio active, in some cases producing periodic pulses. Extensive studies of two such objects have also revealed o…
Volume-limited radio survey of ultracool dwarfs
A. Antonova, G. Hallinan, J. G. Doyle +5
We conducted a volume-limited survey at 4.9 GHz of 32 nearby ultracool dwarfs with spectral types covering the range M7 -- T8. A statistical analysis was performed on the combined…
Modelling the radio pulses of an ultracool dwarf
S. Yu, G. Hallinan, J. G. Doyle +5
Recently unanticipated magnetic activity in ultracool dwarfs (UCDs, spectral classes later than M7) have emerged from a number of radio observations. The highly (up to 100%) circul…
