The Sun as an X-Ray Star. II. Using theYohkoh/Soft X-Ray Telescope-derived Solar Emission Measure versus Temperature to Interpret Stellar X-Ray Observations
- G. Peres, S. Orlando, F. Reale, R. Rosner, H. Hudson
- Physics
- 2000
This paper is the second of a project dedicated to using solar Yohkoh/SXT data as a guide and a template to interpret data on stellar coronae. In the light of the large diUerences in scope and…
Bright X-Ray Flares in Orion Young Stars from COUP: Evidence for Star-Disk Magnetic Fields?
- F. Favata, E. Flaccomio, E. Feigelson
- Physics
- 7 June 2005
We have analyzed a number of intense X-ray flares observed in the Chandra Orion Ultradeep Project (COUP), a 13 day observation of the Orion Nebula Cluster (ONC), concentrating on the events with the…
Diagnostics of stellar flares from X-ray observations: from the decay to the rise phase
- F. Reale
- Physics
- 23 May 2007
Context. The diagnostics of stellar flaring coronal loops have been so far largely based on the analysis of the decay phase. Aims. We derive new diagnostics from the analysis of the rise and peak…
Flares from small to large: X-ray spectroscopy of Proxima Centauri with XMM-Newton
- M. Guedel, M. Audard, F. Reale, S. Skinner, J. Linsky
- Physics
- 11 December 2003
We report results from a comprehensive study of the nearby M dwarf Proxima Centauri with the XMM-Newton satellite, using simultaneously its X-ray detectors and the Optical Monitor with its U band…
XMM-Newton observations of the supernova remnant IC 443: II. evidence of stellar ejecta in the inner regions.
- E. Troja, F. Bocchino, M. Miceli, F. Reale
- Physics
- 7 April 2008
Aims. We investigate the spatial distribution of the physical and chemical properties of the hot X-ray emitting plasma of the supernova remnant IC 443, in order to get important constraints on its…

Crushing of interstellar gas clouds in supernova remnants. I. The role of thermal conduction and radiative losses
- S. Orlando, G. Peres, A. Siegel
- Physics
- 30 August 2005
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 SNR. We investigate…
On the origin of asymmetries in bilateral supernova remnants
- S. Orlando, F. Bocchino, F. Reale, G. Peres, O. Petruk
- Physics
- 6 April 2007
Aims. We investigate whether the morphology of bilateral supernova remnants (BSNRs) observed in the radio band is determined mainly either by a non-uniform interstellar medium (ISM) or by a…
Evidence of nonthermal particles in coronal loops heated impulsively by nanoflares

TLDR
On the observability of T Tauri accretion shocks in the X-ray band
- G. Sacco, S. Orlando, R. Curran
- Physics
- 14 July 2010
Context. High resolution X-ray observations of classical T Tauri stars (CTTSs) show a soft X-ray excess due to high density plasma (ne = 10 11 −10 13 cm −3 ). This emission has been attributed to…
