Solar low-lying cool loops and their contribution to the transition region EUV output
C. Sasso, V. Andretta, D. Spadaro +1
In the last 30 years, the existence of small and cool magnetic loops (height < 8 Mm, T < 10^5 K) has been proposed and debated to explain the increase of the DEM (differential emis…
First detection of acoustic-like flux in the middle solar corona
V. Andretta, L. Abbo, G. Jerse +28
Waves are thought to play a significant role in the heating of the solar atmosphere and the acceleration of the wind. Among the many types of waves observed in the Sun, the so-call…
Comparing extrapolations of the coronal magnetic field structure at 2.5 solar radii with multi-viewpoint coronagraphic observations
C. Sasso, R. F. Pinto, V. Andretta +19
The magnetic field shapes the structure of the solar corona but we still know little about the interrelationships between the coronal magnetic field configurations and the resultin…
A view of the evolution of a CME and the associated wave-trains at high spatial and temporal resolution
G. Russano, Y. De Leo, F. Frassati +13
Context. Studying the kinematic and dynamic evolution of fast eruptive events from the middle to high solar corona is a primary objective of the Metis coronagraph on Solar Orbiter.…
Effects of the chromospheric Lyα line profile shape on the determination of the solar wind HI outflow velocity using the Doppler dimming technique
G. E. Capuano, S. Dolei, D. Spadaro +15
The determination of solar wind outflow velocity is fundamental in order to probe the mechanisms of wind acceleration in the corona. We aim to study, via the Doppler dimming techni…
In-flight validation of Metis Visible-light Polarimeter Coronagraph on board Solar Orbiter
A. Liberatore, S. Fineschi, M. Casti +21
Context. The Metis coronagraph is one of the remote-sensing instruments of the ESA/NASA Solar Orbiter mission. Metis is aimed at the study of the solar atmosphere and solar wind by…
