We present our new scheme for the classification of radial stellar surface brightness profiles for disk galaxies. We summarize the current theoretical attempts...
Three-dimensional numerical experiments of flux emergence into the corona
Understanding the complicated non-linear thermal and magnetodynamic processes observed to continuously reshape the solar atmosphere requires the use of three...
Three-Dimensional Radiative Transfer Modeling of the Scattering Polarization in MgH Lines
Analysis of the Hanle effect in solar molecular lines allows us to obtain empirical information on hidden, mixed-polarity magnetic fields at subresolution...
Three-dimensional Radiative Transfer Modeling of the Second Solar Spectrum of Titanium
Here we present multilevel radiative transfer calculations of the scattering polarization of neutral titanium lines in a three-dimensional model of the solar...
Three-wavelength sun photometer for aerosol characterization
A three-wavelength sun-photometer was designed and built. The attenuation of direct solar light, at wavelengths of 0.38 micrometers , 0.50 micrometers and 1.00...
