The Visible-light Imager and Magnetograph (VIM) proposed for the ESA Solar Orbiter mission will observe a photo spheric spectral line at high spatial resolution...

The SolO-VIM instrument will be a two-dimensional full-Stokes spectro-polarimeter which will provide diffraction-limited vector-magnetograms, Dopplergrams, and...

For the Visible Light Imager and Magnetograph (VIM) a high-resolution filtergraph is under design. The system takes advantage of a lithium niobate (LiNbO3)...

We present deep, high-resolution (R˜40000) UVES at VLT spectrophotometric data of the planetary nebula NGC 3918. This is one of the deepest spectra ever taken...

Approximately half of the elements with atomic number Z > 30 are created by slow neutron-capture process in the stellar interior of low- and intermediate- mass...

The chemical evolution of asymptotic giant branch (AGB) stars depends greatly on the input physics (e.g., mass loss recipe, convective model). Variations in the...
