  • An operator perturbation method for polarized line transfer. III. Applications to the Hanle effect in 1D media 
    Nagendra, K. N; Frisch, H; Faurobert-Scholl, M (European Southern Observatory, 1998-04)
    In this paper we present an Approximate Lambda Iteration method to treat the Hanle effect (resonance scattering in the presence of a weak magnetic field) for lines formed with complete frequency redistribution. The Hanle ...
  • Polarization of L Dwarfs by Dust Scattering 
    Sengupta, S; Kwok, S (The American Astronomical Society, 2005-06)
    The degree of polarization in L dwarfs of spectral types L0-L6 resulting from dust scattering in a rotation-induced oblate photosphere is calculated. Assuming that forsterite is the main condensate, we derive the atmospheric ...
