    On the (Mis)Interpretation of the Scattering Polarization Signatures in the Ca II 8542 Å Line through Spectral Line Inversions
    Scattering polarization tends to dominate the linear polarization signals of the Ca II 8542 Å line in weakly magnetized areas (B ≲ 100 G), especially when the...

    On the application of iteration factors for temperature correction in stellar atmospheres
    The authors present an improved iterative method for deriving temperature corrections in stellar atmospheres. At each step of iteration, the procedure computes...

    On the Effects of the Evolution of Microbial Mats and Land Plants on the Earth as a Planet. Photometric and Spectroscopic Light Curves of Paleo-Earths
    Understanding the spectral and photometric variability of the Earth and the rest of the solar system planets has become of utmost importance for the future...

    On the fate of the most massive stars
    Radiation-driven mass loss largely determines the life expectancy of massive stars. I will present our most recent mass-loss predictions for massive stars...

    On the Formation of Lyman β and the O I 1027 and 1028 Å Spectral Lines
    We study the potential of Lyman β and the O I 1027 and 1028 Å spectral lines to help in understanding the properties of the chromosphere and transition region...

    On the k-mechanism and the multidimensional Eddington approximation
    The suitability of the Eddington approximation as a theoretical framework for the study of the possibility of a k-like overstability mechanism as the driving...

    On the Origin of the Type II Spicules: Dynamic Three-dimensional MHD Simulations
    Recent high temporal and spatial resolution observations of the chromosphere have forced the definition of a new type of spicule, "type II's," that are...

    On the photospheric temperature in small-scale magnetic flux concentrations
    Results are presented of 2D radiative transfer calculations performed for geometric configurations that simulate partly evacuated small-scale magnetic flux...

    On the Probable Existence of an Abrupt Magnetization in the Upper Chromosphere of the Quiet Sun
    We report on a detailed radiative transfer modeling of the observed scattering polarization in the Hα line, which allows us to infer quantitative information on...
