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.

The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access. An OpenURL link containsarticle metadata and directs it to the OpenURL server of your choice. The OpenURL server can provide access to the resource and also offer complementary services (specific search engine, export of references...). The OpenURL link can be generated by different means:
- if your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages,
- you can define your own OpenURL resolver with your EDPS Account. In this case your choice will be given priority over that of your library,
- you can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see http://www.openly.com/openurlref/). You should disable this module if you wish to use the OpenURL server that you or your library have defined.
