  • Observed polarization of brown dwarfs suggests low surface gravity 
    Sengupta, S; Marley, M. S (IOP Publishing, 2010-10-20)
    Light scattering by atmospheric dust particles is responsible for the polarization observed in some L dwarfs. Whether this polarization arises from an inhomogeneous distribution of dust across the disk or an oblate shape ...
