We present some theoretical predictions concerning the amplitudes and magnetic sensitivities of the linear polarization signals produced by scattering processes...

This paper addresses the problem of scattering line polarization and the Hanle effect in one-dimensional (1D), two-dimensional (2D) and three-dimensional (3D)...

This paper reviews some of the most recent advances in the application of the Hanle effect to solar physics, and how these developments are allowing us to...

The Ly α lines of H I and He II are two of the spectral lines of choice for FUV and EUV channels of narrowband imagers on board sounding rockets and space...

When an alt-azimuth telescope is tracking at a specific field, it is necessary to use a de-rotator system to compensate the Earth's rotation of the field of...

This work describes the hardware control system of the Prime Focus Corrector (PFC) and the Spectrograph, two of the main parts of WEAVE, a multi-object fiber...

The first results of a study of F-type MS stars using the He I D3 absorption feature at 5876 A as an indicator of stellar activity and structure are presented...

A study is presented for the realization of the heat stop for the 4-m European Solar Telescope EST, whose feasibility study will be completed in 2011. EST is an...
