The Molecular Hydrogen Explorer H2EX
F. Boulanger, J. P. Maillard, P. Appleton +12
The Molecular Hydrogen Explorer, H2EX, was proposed in response to the ESA 2015 - 2025 Cosmic Vision Call as a medium class space mission with NASA and CSA participations. The miss…
SiO line emission from C-type shock waves : interstellar jets and outflows
A. Gusdorf, S. Cabrit, D. R. Flower +1
We study the production of SiO in the gas phase of molecular outflows, through the sputtering of Si--bearing material in refractory grain cores, which are taken to be olivine; we c…
Discovery of a bipolar X-ray jet from the T Tauri star DG Tau
M. Guedel, S. L. Skinner, M. Audard +2
We have obtained and analyzed Chandra ACIS-S observations of the strongly accreting classical T Tauri star DG Tau. Our principal goals are to map the immediate environment of the s…
PdBI sub-arcsecond study of the SiO microjet in HH212 - Origin and collimation of Class 0 jets
S. Cabrit, C. Codella, F. Gueth +4
The bipolar HH 212 outflow has been mapped in SiO using the extended configuration of the Plateau de Bure Interferometer (PdBI), revealing a highly collimated SiO jet closely assoc…
Depletion and low gas temperature in the L183 prestellar core : the N2H+ - N2D+ tool
Laurent Pagani, Aurore Bacmann, Sylvie Cabrit +1
Context. The study of pre-stellar cores (PSCs) suffers from a lack of undepleted species to trace the gas physical properties in their very dense inner parts. Aims. We want to carr…
A highly-collimated SiO jet in the HH212 protostellar outflow
C. Codella, S. Cabrit, F. Gueth +4
We mapped the HH212 Class 0 outflow in SiO(2--1, 5--4) and continuum using the PdBI in its extended configurations. The unprecedented angular resolution (down to 0.34") allows accu…
Molecular line emission in HH54: a coherent view from near to far infrared
T. Giannini, C. McCoey, B. Nisini +4
Aims. We present a detailed study of the infrared line emission (1-200 micron) in the Herbig-Haro object HH54. Our database comprises: high- (R~9000) and low- (R~600) resolution sp…
Which jet launching mechanism(s) in TTauri stars?
Jonathan Ferreira, Catherine Dougados, Sylvie Cabrit
AIMS: We examine whether ejection phenomena from accreting T Tauri stars can be described by only one type of self-collimated jet model. METHODS: We present analytical kinematic pr…
Temporal evolution of magnetic molecular shocks II. Analytics of the steady state and semi-analytical construction of intermediate ages
P. Lesaffre, J. -P. Chièze, S. Cabrit +1
In the first paper of this series (Paper I) we computed time dependent simulations of multifluid shocks with chemistry and a transverse magnetic field frozen in the ions, using an…
Temporal evolution of magnetic molecular shocks I. Moving grid simulations
P. Lesaffre, J. -P. Chièze, S. Cabrit +1
We present time-dependent 1D simulations of multifluid magnetic shocks with chemistry resolved down to the mean free path. They are obtained with an adaptive moving grid implemente…
Predicted rotation signatures in MHD disc winds and comparison to DG Tau observations
N. Pesenti, C. Dougados, S. Cabrit +4
Motivated by the first detections of rotation signatures in the DG Tau jet (Bacciotti et al. 2002), we examine possible biases affecting the relation between detected rotation sign…
Near-IR [Fe II] emission diagnostics applied to cold disk winds in young stars
N. Pesenti, C. Dougados, S. Cabrit +3
We investigate the emissivity properties of the main near-IR transitions of the Fe+ ion in the conditions prevailing in the inner regions of jets from young stars, based on a simpl…
Proper motions and velocity asymmetries in the RW Aur jet
L. Lopez-MArtin, S. Cabrit, C. Dougados
We present adaptive optics spectro-imaging observations of the RW Aur jet in optical forbidden lines, at an angular resolution of 0.4 arcsec. Comparison with HST data taken 2 years…
Warm Molecular Hydrogen and Ionized Neon in the HH2 Outflow
B. Lefloch, J. Cernicharo, S. Cabrit +3
We report on spectro-imaging observations of the Herbig-Haro 2 outflow with the ISOCAM camera onboard the Infrared Space Observatory (ISO). The [Ne II}] 12.81 microns and [Ne III]1…
