Abstract: |
SOXS is a joint X-ray/IR large survey conducted with XMM-Newton
and Spitzer south of the Orion Nebula Cloud (ONC). By means of
combined IR and X-ray observation we have discovered and
characterized a population of about 1800 PMS stars distributed among Class I,
Class II, transition disk objects and Class III stars.
We report on the X-ray clustering properties of the young stellar
population in L1641 and south of ONC around ι Orionis.
Small clusters of 10–50 Class I / II stars are found in L1641 while Class III objects are
sparse and relatively less numerous. On the contrary, Class III candidates
are more clustered around the star ι Orionis star and this fact suggests
that an age older than ONC and a different star formation history in the suburbs
of ι Orionis has taken place with respect to the ONC. |
