In order to characterized the vertical atmospheric structure at the Teide Observatory (Tenerife, Spain), we are using two different remote sensing technics: SODAR (SOund Detection And Ranging) and SCIDAR (SCIncitillation Detection And Ranging) at this astronomical site. We present in this work the preliminar results on the comparison of the

Atomic Scattering Polarization. Observations, Modeling, Predictions
This paper highlights very recent advances concerning the identification of new mechanisms that introduce polarization in spectral lines, which turn out to be key for understanding some of the most enigmatic scattering polarization signals of the solar visible spectrum. We also show a radiative transfer prediction on the scattering polarization

Automated analysis of stellar spectra
Classical model-atmosphere analyses of stellar spectra usually begin by measuring equivalent widths, and then proceed into a loop in which 1) model spectra are calculated for a set of abundances and atmospheric parameters, and 2) observed and computed spectra are compared and corrections to the abundances and parameters are inferred. Automated

Automated analysis of stellar spectra: application to the GAUDI
In this paper we describe a methodology to be used for the automated analysis of the spectroscopic contents of the GAUDI archive. We perform chi-square minimisation in the 5000-5200 Å spectral window to infer the atmospheric parameters and their random internal uncertainties. Effective temperatures are anchored using a zero-point correction into

B fields in OB stars (BOB): Low-resolution FORS2 spectropolarimetry of the first sample of 50 massive stars
Within the context of the collaboration "B fields in OB stars" (BOB), we used the FORS2 low-resolution spectropolarimeter to search for a magnetic field in 50 massive stars, including two reference magnetic massive stars. Because of the many controversies of magnetic field detections obtained with the FORS instruments, we derived the magnetic field

BaLROG: The Influence of Bars on the Dynamical Structure in Nearby Galaxies
Using the BaLROG (Bars in Low Redshift Optical Galaxies) sample of 16 morphologically distinct barred spirals, we constrain the influence of bars on nearby galaxies observationally. Our sample appears small compared to ongoing IFU surveys, but offers a tenfold sharper spatial resolution (˜100 pc) as each galaxy is a mosaic of several pointings
