Context. Spectropolarimetric inversions are routinely used in the field of solar physics for the extraction of physical information from observations. The...

Inversion techniques of the radiative transfer equation for polarized light are presented as one of the best current procedures to infer the vector magnetic...

Consideration is given to the suppression of the radial and polar escape of magnetic flux in the form of toroidal flux tubes (flux rings) from low latitudes in...

WASP-12b is one of the most well-studied transiting exoplanets, as its highly inflated radius and its 1.1 d orbit around a G0-type star make it an excellent...

We present a new pipeline developed to detect and characterize faint astronomical companions at small angular separation from the host star using sets of wide...

Dark sector particles at the GeV scale carrying baryon number provide an attractive framework for understanding the origin of dark matter and the matter...

Quantitative information about variations in the background at J and K' are presented and used to develop guidelines for the acquisition and reduction of ground...

The low surface brightness (LSB) regime (μ g ≳ 26 mag arcsec -2) comprises a vast, mostly unexplored discovery space, from dwarf galaxies to the diffuse...

This paper explores three different strategies for the inversion of spectral lines (and their Stokes profiles) using artificial neural networks. It is shown...
