The deepest layers of the solar atmosphere are only
partially ionised. As a result,
the presence of neutrals cannot be neglected and they can
influence magnetic
structures in various aspects. Neutrals do not feel directly
the effects of the
Lorentz force and are only sensitive to it through
collisions with charged particles.
The net effect is that these collisions have an impact...

The complexity of the chromosphere is due to various regime
changes that take place
across it. Consequently, the interpretation of chromospheric
observations is a
challenging task. It is thus crucial to combine these
observations with advanced
radiative-MHD numerical modeling. Because the photosphere,
chromosphere and
transition region are partially ionized, the interaction
between...

IRIS observations of chromospheric and CCTR lines, with their unique spatial and
temporal capabilities, allow for a complete diagnostic of the highly dynamical
spicules from their cool roots to their expansion and disappearance into the corona.
We analyzed both spectral and slit-jaw observations near the south pole of the sun,
with the slit perpendicular to the limb. Here we will present...

The balloon-borne SUNRISE observatory allows obtaining observations in the UV with
unprecedented temporal stability and spatial resolution. During its second scientific
flight the Sunrise Filter Imager (SUFI) was used to record a time series of
narrow-band intensity images in the Ca II H line lasting for approximately one hour
at a cadence of 7 seconds. This unique data set enabled us to...
