Multiple scattering polarization of substellar-mass objects: T dwarfs

Sengupta, S; Marley, M. S (American Astronomical Society, 2009-12-10)

While there have been multiple observational programs aimed at detecting linear polarization of optical radiation emitted by ultracool dwarfs, there has been comparatively less rigorous theoretical analysis of the problem. ...
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 ...
A Search for Polarized Thermal Emission from Directly Imaged Exoplanets and Brown Dwarf Companions to Nearby Stars

Jensen-Clem, R; Millar-Blanchaer, M. A; van Holstein, R. G; Mawet, Dimitri; Graham, J; Sengupta, S; Marley, M. S; Snik, Frans; Vigan, A; Hinkley, S; de Boer, Jos; Girard, J. H; De Rosa, R. J; Bowler, B. P; Wiktorowicz, S. J; Perrin, M. D; Crepp, J. R; Macintosh, B (IOP Publishing, 2020-12)

Aerosols in the atmospheres of cloudy gas giant exoplanets and brown dwarfs scatter and polarize these objects' thermal emission. If such an object has an oblate shape or nonuniform cloud distribution, the net degree of ...
