3D MHD astrospheres: applications to IRC-10414 and Betelgeuse
D. M. -A. Meyer, A. Mignone, M. Petrov +3
A significative fraction of all massive stars in the Milky Way move supersonically through their local interstellar medium (ISM), producing bow shock nebulae by wind-ISM interactio…
Proper motions of the HH1 jet
A. C. Raga, B. Reipurth, A. Esquivel +9
We describe a new method for determining proper motions of extended objects, and a pipeline developed for the application of this method. We then apply this method to an analysis o…
Hu1-2: a metal-poor bipolar planetary nebula with fast collimated outflows
Xuan Fang, Martin A. Guerrero, Luis F. Miranda +3
We present narrow-band optical and near-IR imaging and optical long-slit spectroscopic observations of Hu1-2, a Galactic planetary nebula (PN) with a pair of [N II]-bright, fast-mo…
An asymmetric jet launching model for the protoplanetary nebula CRL 618
P. F. Velazquez, A. Riera, A. C. Raga +1
We propose an asymmetrical jet ejection mechanism in order to model the mirror symmetry observed in the lobe distribution of some protoplanetary nebulae (pPNe), such as the pPN CRL…
Unveiling shocks in planetary nebulae
M. A. Guerrero, J. A. Toalá, J. J. Medina +4
The propagation of a shock wave into a medium is expected to heat the material beyond the shock, producing noticeable effects in intensity line ratios such as [O III]/Halpha. To in…
Revisiting 2D Numerical Models for the 19th century outbursts of Carinae
R. F. González, A. M. Villa, G. C. Gómez +5
We present here new results of two-dimensional hydrodynamical simulations of the eruptive events of the 1840s (the great) and the 1890s (the minor) eruptions suffered by the massiv…
