XMM obs. of two regions west to {kappa} Ori
Listed in IVOA Registry (Virtual Observatory)
X-rays are a powerful probe of activity in early stages of star formation.
Description
They allow us to identify young stars even after they have lost the IR signatures of circumstellar disks and provide constraints on their distance. Here, we report on XMM-Newton observations that detect 121 young stellar objects (YSOs) in two fields between L1641S and {kappa} Ori.
These observations extend the Survey of Orion A with XMM and Spitzer (SOXS). The YSOs are contained in a ring of gas and dust apparent at millimeter wavelengths, and in far-IR and near-IR surveys. The X-ray luminosity function of the YSOs detected in the two fields indicates a distance of 250-280pc, much closer than the Orion A cloud and similar to distance estimates of {kappa} Ori.

We propose that the ring is a 5-8pc diameter shell that has been swept up by {kappa} Ori. This ring contains several groups of stars detected by Spitzer and WISE including one surrounding the Herbig Ae/Be stars V1818 Ori. In this interpretation, the {kappa} Ori ring is one of several shells swept up by massive stars within the Orion Eridanus Superbubble and is unrelated to the southern portion of OrionA/L1641S.
