Imaging with Amber/VLTI: the case of microjets

E. Thiébaut, P. J. V. Garcia, R. Foy

The engine that powers pre-main-sequence micro-jets is still unknown and remains a fundamental open question in star formation. The engine can be located solely on the inner disk or in the interaction of the inner disk with the star. In order to ease interpretation problems, imaging the jet engine is the ideal probe to disentangle between the old models and shed evidence for new ones. In this paper, we analyse the feasability of imaging bright southern targets, and show that even at low SNR, accurate image reconstruction is still possible with high contrast. However, the small number of ATs requires a fast reconfigurable array.
