Modeling the scattering polarization of the solar Ca i 4227 Å line with angle-dependent partial frequency redistribution
Gioele Janett, Ernest Alsina Ballester, Nuno Guerreiro +4
Context. The correct modeling of the scattering polarization signals observed in several strong resonance lines requires taking partial frequency redistribution (PRD) phenomena int…
A novel fourth-order WENO interpolation technique. A possible new tool designed for radiative transfer
Gioele Janett, Oskar Steiner, Ernest Alsina Ballester +2
Context. Several numerical problems require the interpolation of discrete data that present various types of discontinuities. The radiative transfer is a typical example of such a…
Discontinuities in numerical radiative transfer
Gioele Janett
Observations and magnetohydrodynamic simulations of solar and stellar atmospheres reveal an intermittent behavior or steep gradients in physical parameters, such as magnetic field,…
Formal Solutions for Polarized Radiative Transfer. IV. Numerical Performances in Practical Problems
Gioele Janett, Oskar Steiner, Luca Belluzzi
The numerical computation of reliable and accurate Stokes profiles is of great relevance in solar physics. In the synthesis process, many actors play a relevant role: among them th…
Formal solutions for polarized radiative transfer. III. Stiffness and instability
Gioele Janett, Alberto Paganini
Efficient numerical approximation of the polarized radiative transfer equation is challenging because this system of ordinary differential equations exhibits stiff behavior, which…
Formal Solutions for Polarized Radiative Transfer. II. High-order Methods
Gioele Janett, Oskar Steiner, Luca Belluzzi
When integrating the radiative transfer equation for polarized light, the necessity of high-order numerical methods is well known. In fact, well-performing high-order formal solver…
