Multi-wavelength differential astrometry of the S5 polar cap sample

, 2004
We report on the status of our S5 polar cap astrometry program. Since 1997 we have observed all the 13 radio sources of the complete S5 polar cap sample at the wavelengths of 3.6 cm, 2 cm and 7 mm. Images of the radio sources at 3.6 and 2 cm have already

Precise Mass, Orbital Motion, and Stellar Properties of the M-dwarf Binary LP 349−25AB

The Astrophysical Journal
LP 349−25 is a well-studied close stellar binary system comprised of two late M dwarf stars, where both stars are close to the limit between star and brown dwarf. This system was previously identified as a source of gigahertz radio emission.

Main-oval Auroral Emission from a T6 Brown Dwarf: Observations, Modeling, and Astrometry

The Astrophysical Journal
From a series of 5 GHz Very Long Baseline Array (VLBA) radio observations taken over a 1 yr span, we present the detection of compact, highly polarized radio emission from the T6 brown dwarf WISE J112254.72+255022.2, compatible with electron cyclotron ...
