Lupus 3 SFR XMM-Newton X-Ray Point Source Catalog

Published by High Energy Astrophysics Science Archive Research Center | National Aeronautics and Space Administration | Metadata Last Checked: October 20, 2025 | Last Modified: 2025-09-10
This table contains the analysis results of an XMM-Newton observation of the Lupus 3 region that contains a high proportion of young low-mass (< 0.3 solar masses) T Tauri stars in the Lupus star-forming complex. The observation had a ~22-ks effective exposure in the pn and MOS cameras. The detection of X-ray sources in 0.5 - 4.5 keV images of the Lupus 3 core was performed using the standard source detection method in the XMM-Newton Science Analysis Software (SAS). 102 candidate X-ray sources were detected with a likelihood threshold of >= 12 (corresponding to 4.4 sigma in Gaussian statistics) in the 30-arcmin diameter field-of-view of the EPIC cameras, of which 25 have visible or near-IR counterparts within the adopted 4" correlation radius for each X-ray source that were known to be pre-main sequence stars. Their X-ray luminosities range from 3 x 10<sup>28</sup> to 3 x 10<sup>30</sup> erg/s. This table gives the list of X-ray sources detected in the core of the Lupus 3 region with the EPIC camera on-board XMM-Newton, except that the X-ray source associated with the star HR 6000 (the nominal target of the XMM-Newton observation of the original PI) has been excluded. Additional information on the optical and IR counterparts of 25 of the X-ray sources, and on the X-ray spectra, is available in the reference paper. This table was created by the HEASARC in Match 2007 based on CDS table J/A+A/454/595 file table6.dat. This is a service provided by NASA HEASARC .
