A far-infrared survey of bow shocks and detached shells around AGB stars and red supergiants
N. L. J. Cox, F. Kerschbaum, A. -J. van Marle +16
Far-infrared Herschel/PACS images at 70 and 160 micron of a sample of 78 Galactic evolved stars are used to study the (dust) emission structures, originating from stellar wind-ISM…
Dust distribution in circumstellar shells
Allard Jan van Marle, Zakaria Meliani, Rony Keppens +1
We present numerical simulations of the hydrodynamical interactions that produce circumstellar shells. These simulations include several scenarios, such as wind-wind interaction an…
Synchrotron radiation of self-collimating relativistic MHD jets
Oliver Porth, Christian Fendt, Zakaria Meliani +1
The goal of this paper is to derive signatures of synchrotron radiation from state-of-the-art simulation models of collimating relativistic magnetohydrodynamic (MHD) jets featuring…
Computing the dust distribution in the bowshock of a fast moving, evolved star
Allard Jan van Marle, Zakaria Meliani, Rony Keppens +1
We study the hydrodynamical behavior occurring in the turbulent interaction zone of a fast moving red supergiant star, where the circumstellar and interstellar material collide. In…
Two-shell collisions in the GRB afterglow phase
A. Vlasis, H. van Eerten, Z. Meliani +1
Strong optical and radio flares often appear in the afterglow phase of Gamma-Ray Bursts (GRBs). It has been proposed that colliding ultra-relativistic shells can produce these flar…
3-D simulations of shells around massive stars
Allard Jan van Marle, Rony Keppens, Zakaria Meliani
As massive stars evolve, their winds change. This causes a series of hydrodynamical interactions in the surrounding medium. Whenever a fast wind follows a slow wind phase, the fast…
