Scientific paper

The complex of Orion Molecular Cloud is the most interesting example
of complex cloud and star forming region. With SOXS program we have
obtained information on the X-ray (with XMM-Newton) and infrared (IR, with
Spitzer) of the young population distributed along NGC1980 and L1641 south
of the Orion Nebula Cloud.
In the framework of studying dynamics and morphology of
star forming regions, we have conducted an optical spectroscopic
follow-up of 37 bona fide Weak-T-Tauri stars in NGC1980/L1641 North,
selected on the basis of their strong X-ray emission and the absence
of IR excesses in Spitzer IRAC bands.
Here we present radial velocities, H-alpha and Lithium equivalent widths
and discuss these in the context of their spatial distribution information
obtained with IR and X-ray observations.
