  • Hydrodynamical instability of extragalactic stratified jets 
    Hanasz, Michał; Sol, Helene (1997-11-20)
    The recent development of tomographic analysis of radio data shows the presence of sheaths around several extragalactic jets. We have studied the Kelvin-Helmholtz instability of such stratified jets, describing them as ...
  • Influence of internal energy on the stability of relativistic flows 
    Perucho, Manuel; Hanasz, Michał; Marti, Jose-Maria; Sol, Helene (2002-12-05)
    A set of simulations concerning the influence of internal energy on the stability of relativistic jets is presented. Results show that perturbations saturate when the amplitude of the velocity perturbation approaches the ...
  • Kelvin-Helmholtz instability of stratified jets 
    Hanasz, Michał; Sol, Helene (1996-04-25)
    We investigate the Kelvin-Helmholtz instability of stratified jets. The internal component (core) is made of a relativistic gas moving with a relativistic bulk speed. The second component (sheath or envelope) flows between ...
  • Stability of hydrodynamical relativistic planar jets. I. Linear evolution and saturation of Kelvin-Helmholtz modes 
    Perucho, Manuel; Hanasz, Michał; Marti, Jose-Maria; Sol, Helene (2004-07-27)
    The effects of relativistic dynamics and thermodynamics in the development of Kelvin-Helmholtz instabilities in planar, relativistic jets along the early phases (namely linear and saturation phases) of evolution has been ...
