Coronal Heating Rate in the Slow Solar Wind

Daniele Telloni, Marco Romoli, Marco Velli +59

This Letter reports the first observational estimate of the heating rate in the slowly expanding solar corona. The analysis exploits the simultaneous remote and local observations…

Coronal energy release by MHD avalanches. Effects on a structured, active region, multi-threaded coronal loop

G. Cozzo, J. Reid, P. Pagano +2

A possible key element for large-scale energy release in the solar corona is an MHD kink instability in a single twisted magnetic flux tube. An initial helical current sheet fragme…

Connecting Solar Orbiter remote-sensing observations and Parker Solar Probe in-situ measurements with a numerical MHD reconstruction of the Parker spiral

Ruggero Biondo, Alessandro Bemporad, Paolo Pagano +21

As a key feature, NASA's Parker Solar Probe (PSP) and ESA-NASA's Solar Orbiter (SO) missions cooperate to trace solar wind and transients from their sources on the Sun to the inner…

Tracing the ICME plasma with a MHD simulation

Ruggero Biondo, Paolo Pagano, Fabio Reale +1

The determination of the chemical composition of interplanetary coronal mass ejection (ICME) plasma is an open issue. More specifically, it is not yet fully understood how remote s…

X-ray flares of the young planet host DS Tuc A

I. Pillitteri, C. Argiroffi, A. Maggio +5

Abridged. We observed the 40 Myr old star DS Tuc A with XMM-Newton and recorded two X-ray bright flares, with the second event occurring about 12 ks after the first one. Their dura…

The Solar X-ray Corona

Paola Testa, Fabio Reale

The X-ray emission from the Sun reveals a very dynamic hot atmosphere, the corona, which is characterized by a complex morphology and broad range of timescales of variability and s…
