Linewidths of low-degree acoustic modes of the sun
Estimates of the spectral linewidths of low degree (l = 0 and l = 1), 5-min p-modes obtained from Doppler shift observations in 1984 (63 d) and 1986 (63 d) are...
Long Characteristics versus Short Characteristics in 3D Radiative Transfer Simulations of Polarized Radiation
We compare maps of scattering polarization signals obtained from three-dimensional (3D) radiation transfer calculations in a magnetoconvection model of the...
LTE polarized radiative transfer through interlaced atmospheres
We show that the solution of the radiative transfer equation (RTE) through a line of sight that pierces several times two alternate atmospheres can be obtained...
Techniques involved in measurements of solar magnetic field are based on the observation and interpretation of the polarization signal in suitable Fraunhofer...
Magnetic field strength in solar flux tubes - A model atmosphere independent determination
The "line ratio method" (Stenflo, 1973) has been extensively used in the past to carry out measurements of the magnetic field strength in spatially unresolved...
Multidimensional energy transfer by radiation in the solar atmosphere
Both linear and nonlinear analysis are used to gain a better understanding of the effects of multi-dimensional transfer of energy by radiation in spatially...
