cds-question@unistra.fropen-star-clustersx-ray-sourcesinfrared-photometryWe report on the analysis of an archival observation of part of the {alpha} Persei cluster obtained with XMM-Newton. We detected 102 X-ray sources in the band 0.3-8.0 keV, of which 39 of them are associated with the cluster as evidenced by appropriate magnitudes and colors from Two Micron All Sky Survey photometry. We extend the X-ray luminosity distribution (XLD) for M dwarfs, to add to the XLD found for hotter dwarfs from spatially extensive surveys of the whole cluster by ROSAT. Some of the hotter stars are identified as a background, possible slightly older group of stars at a distance of approximately 500 pc.2013AJ....145..143Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/145/143CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/xmm : XMM-Newton Observation Log (XMM-Newton Science Operation Center, 2012)II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)V/80 : Low-Mass Stars' Membership in Alpha Persei Cluster (Prosser 1992)J/MNRAS/426/3403 : UKIDSS-GCS {alpha} Per members (Lodieu+, 2012)J/MNRAS/367/781 : XMM observations of NGC 2547 (Jeffries+, 2006)J/A+A/416/125 : RI photometry in alpha Per and Pleiades (Deacon+, 2004)J/A+A/421/175 : XMM sources in Blanco 1 (Pillitteri+, 2004)J/AN/319/215 : Alpha Per cluster low-mass members.
