On the cool nature of coronal nanojets
Gabriele Cozzo, Paola Testa, Juan Martinez-Sykora +5
Reconnection-driven nanoflares are widely considered a leading mechanism for coronal-loop heating, but their direct fingerprints in the tenuous coronal plasma remain elusive. The r…
A stellar flare-coronal mass ejection event revealed by X-ray plasma motions
C. Argiroffi, F. Reale, J. J. Drake +6
Coronal mass ejections (CMEs), often associated with flares, are the most powerful magnetic phenomena occurring on the Sun. Stars show magnetic activity levels up to 10^4 times hig…
Magnetic shuffling of coronal downdrafts
A. Petralia, F. Reale, S. Orlando
Channelled fragmented downflows are ubiquitous in magnetized atmospheres, and have been recently addressed from an observation after a solar eruption. We study the possible back-ef…
EUV flickering of solar coronal loops: a new diagnostic of coronal heating
E. Tajfirouze, F. Reale, G. Peres +1
A previous work of ours found the best agreement between EUV light curves observed in an active region core (with evidence of super-hot plasma) and those predicted from a model wit…
Thermal structure of hot non-flaring corona from Hinode/EIS
A. Petralia, F. Reale, P. Testa +1
In previous studies a very hot plasma component has been diagnosed in solar active regions through the images in three different narrow-band channels of SDO/AIA. This diagnostic fr…
X-raying hot plasma in solar active regions with the SphinX spectrometer
M. Miceli, F. Reale, S. Gburek +7
The detection of very hot plasma in the quiescent corona is important for diagnosing heating mechanisms. The presence and the amount of such hot plasma is currently debated. The Sp…
Nanoflare Evidence from Analysis of the X-Ray Variability of an Active Region Observed with Hinode/XRT
S. Terzo, F. Reale, M. Miceli +3
The heating of the solar corona is one of the big questions in astrophysics. Rapid pulses called nanoflares are among the best candidate mechanisms. The analysis of the time variab…
On the importance of background subtraction in the analysis of coronal loops observed with TRACE
S. Terzo, F. Reale
In the framework of TRACE coronal observations, we compare the analysis and diagnostics of a loop after subtracting the background with two different and independent methods. The d…
