| Abstract: | The study of Young Stellar Objects (YSOs) is one of the most exciting topics that can be undertaken by long baseline optical
interferometry. The magnitudes of these objects are at the edge of capabilities of current optical interferometers, limiting
the studies to a few dozen, but are well within the capability of coming large aperture interferometers like the VLT Interferometer,
the Keck Interferometer, the Large Binocular Telescope or 'OHANA. The milli-arcsecond spatial resolution reached by interferometry
probes the very close environment of young stars, down to a tenth of an astronomical unit. In this paper, I review the different
aspects of star formation that can be tackled by interferometry: circumstellar disks, multiplicity, jets. I present recent
observations performed with operational infrared interferometers, IOTA, PTI and ISI, and I show why in the next future one
will extend these studies with large aperture interferometers.
