On the matter entrainment by stellar jets and the acceleration of molecular outflows
M. Micono, G. Bodo, S. Massaglia +2
We study, by numerical simulations, the entrainment process in a supersonic, radiative jet flow, during the evolution of Kelvin-Helmholtz instabilities, in the context of the the a…
Kelvin-Helmholtz instability in three dimensional radiative jets
M. Micono, G. Bodo, S. Massaglia +3
The analysis of the stability properties of astrophysical jets against Kelvin-Helmholtz (or shear-layer) instabilities plays a basic role in the understanding the origin and physic…
Understanding NLR in Seyfert Galaxies: numerical simulation of jet-cloud interaction
P. Rossi, A. Capetti, G. Bodo +2
Recent HST observations suggest that the NLR in Seyfert Galaxies can be the result of interaction between jet and external inhomogeneous medium; following this suggestion we perfor…
Acoustic Waves in a Stratified Atmosphere: II. Three-Dimensional Hydrodynamics
G. Bodo, W. Kalkofen, S. Massaglia +1
We investigate analytically the propagation of linear waves in a three-dimensional, nonmagnetic, isothermal atmosphere stratified in plane-parallel layers. The motivation is to stu…
Phase Variability in the Optical Polarization of GRO J1655--40
M. Gliozzi, G. Bodo, G. Ghisellini +2
We present the results of the new optical polarimetric observations of the superluminal source GRO J1655--40, carried out in July 1997, with the multichannel photopolarimeter of th…
