Three-dimensional modeling of the asymmetric blast wave from the 2006 outburst of RS Ophiuchi: Early X-ray emission
S. Orlando, J. J. Drake, J. M. Laming
Chandra/HETG observations of the recurrent nova RS Ophiuchi at day 13.9 of its 2006 outburst reveal a spectrum covering a large range in plasma temperature and characterized by asy…
X-ray emission from dense plasma in CTTSs: Hydrodynamic modeling of the accretion shock
G. G. Sacco, C. Argiroffi, S. Orlando +3
High spectral resolution X-ray observations of CTTSs demonstrate the presence of plasma at T~2-3X10^6 K and n_e~10^11-10^13 cm^-3, unobserved in non-accreting stars. Stationary mod…
Non-equilibrium of Ionization and the Detection of Hot Plasma in Nanoflare-heated Coronal Loops
Fabio Reale, Salvatore Orlando
Impulsive nanoflares are expected to transiently heat the plasma confined in coronal loops to temperatures of the order of 10 MK. Such hot plasma is hardly detected in quiet and ac…
Modeling magnetohydrodynamics and non equilibrium SoHO/UVCS line emission of CME shocks
P. Pagano, J. C. Raymond, F. Reale +1
We provide a guideline to interpret the UVCS emission lines (in particular O VI and Si XII) during shock wave propagation in the outer solar corona. We use a numerical MHD model pe…
The importance of magnetic-field-oriented thermal conduction in the interaction of SNR shocks with interstellar clouds
S. Orlando, F. Bocchino, F. Reale +2
We explore the importance of magnetic-field-oriented thermal conduction in the interaction of supernova remnant (SNR) shocks with radiative gas clouds and in determining the mass a…
On the Origin of Asymmetries in Bilateral Supernova Remnants
S. Orlando, F. Bocchino, F. Reale +2
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…
