Abstract

As part of our on-going investigation into the magnetic field properties of ultracool dwarfs, we present simultaneous radio, X-ray, and Hα observations of three M9.5-L2.5 dwarfs (BRI 0021-0214, LSR060230.4+391059, and 2MASS J052338.2−140302). We do not detect X-ray or radio emission from any of the ...
