Abstract

To understand star formation and its evolution, one needs to solve the problem of ejection and collimation mechanisms in jets from young stars. By measuring the jet opening angle at the ejection region we can test models for jet origin. However this very small region cannot be investigated with current monolithic telescopes. Only the AMBER near-IR instrument coupled with the VLTI provides enough resolution to reach the ejection region and enough spectral resolution/coverage to properly separate the emission line jet from the continuum. In this proposal we show that expected visibilities from jets can constrain the jet opening angle.
