Multiple and Precessing Collimated Outflows in the Planetary Nebula IC 4634
M. A. Guerrero, L. F. Miranda, A. Riera +6
With its remarkable double-S shape, IC 4634 is an archetype of point-symmetric planetary nebulae (PN). In this paper, we present a detailed study of this PN using archival HST WFPC…
A precessing jet model for the PN K 3-35: simulated radio-continuum emission
P. Velazquez, Y. Gomez, A. Esquivel +1
The bipolar morphology of the planetary nebula (PN) K 3-35 observed in radio-continuum images was modelled with 3D hydrodynamic simulations with the adaptive grid code yguazu-a. We…
Emission lines from rotating proto-stellar jets with variable velocity profiles. I. Three-dimensional numerical simulation of the non-magnetic case
A. H. Cerqueira, P. F. Velazquez, A. C. Raga +2
Using the Yguazu-a three-dimensional hydrodynamic code, we have computed a set of numerical simulations of heavy, supersonic, radiatively cooling jets including variabilities in bo…
Numerical Modeling of Eta Carinae Bipolar Outflows
R. F. Gonzalez, E. M. de Gouveia Dal Pino, A. C. Raga +1
In this paper, we present two-dimensional gas dynamic simulations of the formation and evolution of the eta-Car bipolar outflows. Adopting the interacting nonspherical winds model,…
Time-dependent ejection velocity model for the outflow of Hen 3--1475
P. F. Velazquez, A. Riera, A. C. Raga
We present 2D axisymmetric and 3D numerical simulations of the proto-planetary nebula Hen 3-1475, which is characterized by a remarkably highly collimated optical jet, formed by a…
A Supernova Remnant Collision with a Stellar Wind
Pablo F. Velazquez, Gloria Koenigsberger, Alejandro C. Raga
Numerical simulations of the interaction between supernova ejecta and a stellar wind are presented. We follow the temporal evolution of the shock fronts that are formed through suc…
