3-D Kinematics of the HH 110 jet
Rosario Lopez, Robert Estalella, Alejandro C. Raga +3
We present new results on the kinematics of the jet HH 110. New proper motion measurements have been calculated from [SII] CCD images obtained with a time baseline of nearly fiftee…
Looking for outflows from brown dwarfs
E. Masciadri, A. C. Raga
First evidences of IR excess and disk mass accretion (strong H emission) around brown dwarfs seem to indicate the existence of circumstellar disks around these sub-stellar objec…
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,…
Minihalo photoevaporation during cosmic reionization: evaporation times and photon consumption rates
Ilian T. Iliev, Paul R. Shapiro, Alejandro C. Raga
The weak, R-type ionization fronts (I-fronts) which swept across the intergalactic medium (IGM) during the reionization of the universe often found their paths blocked by cosmologi…
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…
Hydrodynamical interaction between an accretion flow and a stellar wind
S. Mendoza, J. Canto, A. Raga
Molecular clouds in the interstellar medium suffer gravitational instabilities that lead to the formation of one or multiple stars. A recently formed star inside a cold cloud commu…
