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…
Widespread nanoflare variability detected with Hinode/XRT in a solar active region
Sergio Terzo, Fabio Reale, Marco Miceli +3
It is generally agreed that small impulsive energy bursts called nanoflares are responsible for at least some of the Sun's hot corona, but whether they are the explanation for most…
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…
