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

Determining the magnetic field related to solar spicules is vital for developing adequate models of these plasma jets, which are thought to play a key role in the thermal, dynamic, and magnetic structure of the chromosphere. Here we report on the magnetic properties of off-limb spicules in a very quiet region of the solar atmosphere, as inferred
