Abstract
High-resolution multi-band spectra are a fundamental tool to investigate the inner regions of young stellar objects (YSOs) and thus probe the processes that involve interaction between star and disk, like the accretion and ejection of matter. Recent works with VLT/X-Shooter have shown the potential of wide-band simultaneous spectroscopic observations to provide a full characterization of both the stellar and accretion properties of YSOs. X-Shooter results give us an exciting preview of what E-ELT and HIRES will achieve with a much more increased spatial/spectral resolution and sensitivity. Exploiting HIRES high-resolution coupled with spatially-resolved information at the diffraction limit of the E-ELT will reveal the dynamics, chemistry, and physical conditions of the innermost regions of the disks, thus providing unprecedented constraints on the physics of the accretion, on the jet-launching mechanism and on the planetary formation. A few scientific cases for which HIRES is expected to provide breakthrough results are presented.
