Understanding the Radio Emission from Eridani
Luis F. Rodriguez, Susana Lizano, Jorge Canto +1
Some solar-type stars are known to present faint, time-variable radio continuum emission whose nature is not clearly established. We report on Jansky Very Large Array observations…
Catching the Butterfly and the Homunculus of Carinae with ALMA
Luis A. Zapata, Laurent Loinard, Manuel Fernández-López +7
The nature and origin of the molecular gas component located in the circumstellar vicinity of Carinae are still far from being completely understood. Here, we present Atacama L…
First detection of thermal radio jets in a sample of proto-brown dwarf candidates
O. Morata, A. Palau, R. F. González +10
We observed with the JVLA at 3.6 and 1.3 cm a sample of 11 proto-brown dwarf candidates in Taurus in a search for thermal radio jets driven by the most embedded brown dwarfs. We de…
Compact radio sources in M17
Luis F. Rodriguez, Ricardo F. Gonzalez, Gabriela Montes +3
The classic HII region M17 is one of the best studied across the electromagnetic spectrum. We present sensitive, high angular resolution observations made with the Jansky Very Larg…
Radio continuum emission from knots in the DG Tau jet
L. F. Rodriguez, R. F. Gonzalez, A. C. Raga +5
Context: HH 158, the jet from the young star DG Tau, is one of the few sources of its type where jet knots have been detected at optical and X-ray wavelengths. Aims: To search, usi…
A model for the thermal radio-continuum emission from radiative shocks in colliding stellar winds
G. Montes, R. F. Gonzalez, J. Canto +2
Aims. The interaction of two isotropic stellar winds is studied in order to calculate the free-free emission from the wind collision region. The effects of the binary separation an…
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…
3D numerical model of the Omega Nebula (M17): simulated thermal X-ray emission
J. Reyes-Iturbide, P. F. Velazquez, M. Rosado +3
We present 3D hydrodynamical simulations of the superbubble M17, also known as the Omega nebula, carried out with the adaptive grid code yguazu'-a, which includes radiative cooling…
Disentangling the Nature of the Radio Emission in Wolf Rayet Stars
Gabriela Montes, Miguel A. Perez-Torres, Antxon Alberdi +1
We present quasi-simultaneous, multi-frequency VLA observations at 4.8, 8.4, and 22.5 GHz, of a sample of 13 Wolf Rayet (WR) stars, aimed at disentangling the nature of their radio…
The Nature of the Velocity Field in Molecular Clouds. I. The Non-Magnetic Case
Enrique Vazquez-Semadeni, Ricardo F. Gonzalez, Javier Ballesteros-Paredes +2
We present three numerical simulations of randomly driven, isothermal, non-magnetic, self-gravitating turbulence with different rms Mach numbers Ms and physical sizes L, but approx…
Molecular cloud evolution. I. Molecular cloud and thin CNM sheet formation
Enrique Vazquez-Semadeni, Dongsu Ryu, Thierry Passot +2
We discuss molecular cloud formation by large-scale supersonic compressions in the diffuse warm neutral medium (WNM). Initially, a shocked layer forms, and within it, a thin cold l…
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,…
