Our sample corresponds to optical counterparts of X-ray sources detected from observations with the XMM-Newton satellite, which revealed dozens of possible low-mass young stars not yet known in this region.\n  A sample of 58 young star candidates were selected based on optical spectral features, mainly H{\\alpha} and lithium lines, observed with multi-objects spectroscopy performed by the Gemini South telescope.
