The flaring and quiescent components of the solar corona
C. Argiroffi, G. Peres, S. Orlando +1
The solar corona is a template to understand stellar activity. The Sun is a moderately active star, and its corona differs from active stars: active stellar coronae have a double-p…
Crushing of interstellar gas clouds in supernova remnants. I. The role of thermal conduction and radiative losses
S. Orlando, G. Peres, F. Reale +4
We model the hydrodynamic interaction of a shock wave of an evolved supernova remnant with a small interstellar gas cloud like the ones observed in the Cygnus loop and in the Vela…
Modeling an X-ray Flare on Proxima Centauri: evidence of two flaring loop components and of two heating mechanisms at work
F. Reale, M. Guedel, G. Peres +1
We model in detail a flare observed on Proxima Centauri with the EPIC-PN on board XMM-Newton at high statistics and high time resolution and coverage. Time-dependent hydrodynamic l…
Modeling Non-Confined Coronal Flares: Dynamics and X-Ray Diagnostics
F. Reale, F. Bocchino, G. Peres
Long-lasting, intense, stellar X-ray flares may approach conditions of breaking magnetic confinement and evolving in open space. We explore this hypothesis with hydrodynamic simula…
Coronal loop hydrodynamics. The solar flare observedon November 12 1980 revisited: the UV line emission
R. M. Betta, G. Peres, F. Reale +1
We revisit a well-studied solar flare whose X-ray emission originating from a simple loop structure was observed by most of the instruments on board SMM on November 12 1980. The X-…
Deep ROSAT-HRI observations of the NGC 1399/NGC 1404 region: morphology and structure of the X-ray halo
M. Paolillo, G. Fabbiano, G. Peres +1
We present the analysis of a deep (167 ks) ROSAT HRI observation of the cD galaxy NGC 1399 in the Fornax cluster. Using both HRI and, at larger radii, archival PSPC data, we find t…
