PublicaciónTime series of high resolution photospheric spectra in a quiet region of the Sun. II. Analysis of the variation of physical quantities of granular structures
From the inversion of a time series of high resolution slit spectrograms obtained from the quiet sun, the spatial and temporal distribution of the...

PublicaciónTime-resolved infrared emission from radiation-driven central obscuring structures in active galactic nuclei
The central engines of Seyfert galaxies are thought to be enshrouded by geometrically thick gas and dust structures. In this paper, we derive observable...

PublicaciónTwo-dimensional Radiative Magnetohydrodynamic Simulations of Partial Ionization in the Chromosphere. II. Dynamics and Energetics of the Low Solar Atmosphere
We investigate the effects of interactions between ions and neutrals on the chromosphere and overlying corona using 2.5D radiative MHD simulations with the...

PublicaciónType Ia supernovae with and without blueshifted narrow Na I D lines - how different is their structure?
In studies on intermediate- and high-resolution spectra of Type Ia supernovae (SNe Ia), some objects exhibit narrow Na I D absorptions often blueshifted with...

PublicaciónUltracool Subdwarfs: The Halo Population Down to the Substellar Limit
Ultracool subdwarfs are low luminosity, late-type M and L dwarfs that exhibit spectroscopic indications of subsolar metallicity and halo kinematics. Their...

PublicaciónVenus transit 2004: Illustrating the capability of exoplanet transmission spectroscopy
The transit of Venus in 2004 offered the rare possibility to remotely sense a well-known planetary atmosphere using ground-based absorption spectroscopy...

PublicaciónWarm Water Vapor around Sagittarius B2
Several condensations heated externally by nearby hot stars are present in the Sgr B2 region for which H2O far-IR lines are expected to probe only an external...

PublicaciónZero-Field Dichroism in the Solar Chromosphere
We explain the linear polarization of the Ca ii infrared triplet observed close to the edge of the solar disk. In particular, we demonstrate that the physical...
