A Mini-survey of Ultracool Dwarfs at 4.9 GHz
A. Antonova, J. G. Doyle, G. Hallinan +2
A selection of ultracool dwarfs are known to be radio active, with both gyrosynchrotron emission and the electron cyclotron maser instability being given as likely emission mechani…
Confirmation of the Electron Cyclotron Maser Instability as the Dominant Source of Radio Emission from Very Low Mass Stars and Brown Dwarfs
G. Hallinan, A. Antonova, J. G. Doyle +3
We report on radio observations of the M8.5 dwarf LSR J1835+3259 and the L3.5 dwarf 2MASS J00361617+1821104, which provide the strongest evidence to date that the electron cyclotro…
Rotational Modulation of M/L Dwarfs due to Magnetic Spots
C. Lane, G. Hallinan, R. T. Zavala +7
We find periodic I-band variability in two ultracool dwarfs, TVLM 513-46546 and 2MASS J00361617+1821104, on either side of the M/L dwarf boundary. Both of these targets are short-p…
Rotational Modulation of the Radio Emission from the M9 Dwarf TVLM 513-46546: Broadband Coherent Emission at the Substellar Boundary?
G. Hallinan, A. Antonova, J. G. Doyle +3
The Very Large Array was used to observe the ultracool, rapidly rotating M9 dwarf TVLM 513-46546 simultaneously at 4.88 GHz and 8.44 GHz. The radio emission was determined to be pe…
