Abstract

AMBER is a 3 beam combiner for the Very Large Telescope Interferometer (VLTI). It will soon add to VLTI tremendous angular resolution, sensitivity and spectral resolution (λ/Δλ) up to 10,000. This combination opens important new opportunities for the study of the close environment of pre-main-sequence stars. In order to understand star formation and its evolution, one needs to solve the problem of ejection and collimation mechanisms in jets from young stars. The importance of jets in pre-main-sequence stars relies on the fact that they regulate its angular momentum. By measuring the jet opening angle at the ejection region we can test models for jet origin. In particular, AMBER will provide crucial information on the mechanisms of mass loss and collimation observed in the most active objects. It will allow, for the first time, the differentiation of competing models for jet origin and collimation, namely the X-wind model of Shu and the disk-wind model of Blandford & Payne. In this paper we compare different jet models presented in the literature.
