We investigated the capability of mapping the solar wind outflow velocity of neutral hydrogen
atoms by using synergistic visible-light and ultraviolet observations. We used polarised …

METIS (Multi Element Telescope for Imaging and Spectroscopy) METIS, the “Multi Element
Telescope for Imaging and Spectroscopy”, is a coronagraph selected by the European …

This work combined coronagraphic visible light (VL) and UV data to provide with an
unprecedented view of the inner corona where the nascent solar wind is accelerated. The …

Single layer mirrors have been prepared by evaporating gold and iridium on silicon
substrates. The samples have been exposed to 4 keV He+ ion flux at different total fluences …

Due to the scarcity of UV–EUV observations of coronal mass ejections (CMEs) far from the
Sun (ie, at heliocentric distances larger than 1.5 R sun) our understanding of the …

Future space missions will operate in increasingly hostile environments, such as those in
low-perihelion solar orbits and Jovian magnetosphere. This exploration involves the …

Context. The determination from coronagraphic observations of physical parameters of the
plasma embedded in coronal mass ejections (CMEs) is of crucial importance for our …

Future solar missions will investigate the Sun from very close distances and optical
components are constantly exposed to low energy ions irradiation. In this work we present …

In this work, UV and white-light (WL) coronagraphic data are combined to derive the full set
of plasma physical parameters along the front of a shock driven by a coronal mass ejection …

Context. Empirical relations between major UV and extreme UV spectral lines are one of the
inputs for models of chromospheric and coronal spectral radiances and irradiances. They …
