Accretion funnels onto weakly magnetized young stars
N. Bessolaz, C. Zanni, J. Ferreira +2
Aims : We re-examine the conditions required to steadily deviate an accretion flow from a circumstellar disc into a magnetospheric funnel flow onto a slow rotating young forming st…
MHD simulations of jet acceleration from Keplerian accretion disks: the effects of disk resistivity
C. Zanni, A. Ferrari, R. Rosner +2
Accretion disks and astrophysical jets are used to model many active astrophysical objects, viz., young stars, relativistic stars, and active galactic nuclei. In this paper we pres…
PLUTO: a Numerical Code for Computational Astrophysics
A. Mignone, G. Bodo, S. Massaglia +4
We present a new numerical code, PLUTO, for the solution of hypersonic flows in 1, 2 and 3 spatial dimensions and different systems of coordinates. The code provides a multi-physic…
Heating groups and clusters of galaxies: the role of AGN jets
C. Zanni, G. Murante, G. Bodo +3
X-Ray observations of groups and clusters of galaxies show that the Intra-Cluster Medium (ICM) in their cores is hotter than expected from cosmological numerical simulations of clu…
X-ray emission from expanding cocoons
C. Zanni, G. Bodo, P. Rossi +3
X-ray observations of extragalactic radiosources show strong evidences of interaction between the radio emitting plasma and the X-ray emitting ambient gas. In this paper we perform…
