The study if the large scale structure and properties of the Milky Way has always walked hand in hand with the availability of photometric and spectroscopic...

Metal opacity shapes the near-UV spectrum of late-type stars, which dominate intermediate and old stellar populations. Learning the details of how metal opacity...

The observations were made on 2003 March 30 with the UVES, at the VLT Kueyen Telescope in Cerro Paranal Observatory (Chile). We used the standard settings in...

In the present work, we investigate the formation of Stokes profiles and spectro-polarimetric diagnostics in an active region plage near the limb. We use 3-D...

A few years before the Hinode space telescope was launched, an investigation based on the Hanle effect in atomic and molecular lines indicated that the bulk of...

Full-Stokes spectropolarimetric data (in the 10830 Å region) of an active region filament were obtained in July 2005 using the Tenerife Infrared Polarimeter...

This paper reviews some recent advances in the development and application of polarized radiation diagnostics to infer the mean magnetization of the quiet solar...

The BL Lac object OJ287 has been studied with the 4.2m William Herschel Telescope (WHT) from the Spanish Observatory of La Palma on six nights in December 1993...
