Metrics of Astrometric Variability in the International Celestial Reference Frame. I. Statistical Analysis and Selection of the Most Variable Sources

The Astrophysical Journal Supplement Series
Using very long baseline interferometry data for the sources that comprise the third International Celestial Reference Frame (ICRF3), we examine the quality of the formal source-position uncertainties of ICRF3 by determining the excess astrometric ...

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 ...
