  • Polarization : proving ground for methods in radiative transfer 
    Nagendra, K. N; Anusha, L. S; Sampoorna, M (Societa Astronomica Italiana, 2009)
    Polarization of solar lines arises due to illumination of radiating atom by anisotropic (limb darkened/brightened) radiation. Modelling the polarized spectra of the Sun and stars requires solution of the line radiative ...
  • Projection methods for line radiative transfer in spherical media 
    Anusha, L. S; Nagendra, K. N (Societa Astronomica Italiana, 2009)
    An efficient numerical method called the Preconditioned Bi-Conjugate Gradient (Pre-BiCG) method is presented for the solution of radiative transfer equation in spherical geometry. A variant of this method called Stabilized ...
