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, LSR 060230.4+391059, and 2MASS J052338.2-140302). We do not detect X-ray or radio emission from any of the three sources, despite previous detections of

The Milky Way's thick disk was originally identified by fitting the vertical density distribution of stars to a double exponential profile. Recent investigations have shown that, in addition to being older, thick disk stars show chemical and kinematical properties distinct from the thin disk. Most scenarios of thick disk formation discussed to date

L-type brown dwarfs (Teff = 1400-2100K) are known for their dusty photospheres. Brown dwarfs may have asymmetric surfaces arising from rotationally-induced flattening or large-scale cloud cover and patchiness. This broken symmetry may prevent polarization by dust-scattering to to cancel out, resulting in a non-zero polarization. Therefore, studying

The Planet Hunting and Asteroseismology Explorer Spectrophotometer, PHASES, is a concept for a space-borne instrument to obtain flux calibrated spectra and measure micro-magnitude photometric variations of nearby stars. The science drivers are the determination of the physical properties of stars and the characterisation of planets orbiting them
