Radio Activity from the Rapidly Rotating T dwarf 2MASS 2228-4310
Kelvin Wandia, Michael A. Garrett, Aaron Golden +7
We present the detection of 2MASS J22282889-4310262 (2M2228), a T6/T6.5 brown dwarf, using the Karl G. Jansky Very Large Array (VLA) archival data observed at C band (4-8 GHz) over…
Impact of Electron Precipitation on Brown Dwarf Atmospheres and the Missing Auroral H Emission
J. Sebastian Pineda, Gregg Hallinan, Jean Michel Desert +1
Recent observations have demonstrated that very-low mass stars and brown dwarfs are capable of sustaining strong magnetic fields despite their cool and neutral atmospheres. These k…
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…
