Carina OB1 Association XMM-Newton X-Ray Point Source Catalog CARINAXMM ivo://nasa.heasarc/carinaxmm NASA/GSFC HEASARC Antokhin et al. 2026-10-09 NASA/GSFC HEASARC help desk heasarc-vo at athena.gsfc.nasa.gov Survey Source This database table contains the Carina OB1 Association XMM-Newton X-Ray Point Source Catalog. The X-ray properties of the stellar population in the Carina OB1 Association have been examined with special emphasis on early-type stars. Their spectral characteristics provide some clues to understanding the nature of X-ray formation mechanisms in the winds of single and binary early-type stars. A timing and spectral analysis of five observations with XMM-Newton is performed using various statistical tests and thermal spectral models. 235 point sources have been detected within the field of view. Several of these sources are probably pre-main sequence stars with characteristic short-term variability. Seven sources are possible background AGNs. X-ray count rates in three energy bands and the X-ray variability status are given for 557 detections of the 235 point source. Cross-identifications of X-ray sources with optical and infrared catalogs are also presented. This table was created by the HEASARC in April 2008 based on &lt;a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/A+A/477/593"&gt;CDS Catalog J/A+A/477/593&lt;/a&gt; files table2.dat and table3.dat.
