J/A+A/456/977       XMM observations of NGC 2516 stars       (Marino+, 2006)

X-ray variability of NGC 2516 stars in the XMM-Newton observations. Marino A., Micela G., Pillitteri I., Peres G. <Astron. Astrophys., 456, 977-983 (2006)> =2006A&A...456..977M
ADC_Keywords: Clusters, open ; Stars, late-type ; X-ray sources ; Photometry, UBVRI Keywords: X-ray: stars - stars: activity - stars: early-type - stars: late-type - stars: coronae - galaxy: open clusters and associations: individual: NGC 2516 Abstract: We present the characteristics of the X-ray variability of stars in the cluster NGC 2516 as derived from XMM-Newton/EPIC/pn data. The X-ray variations on short (hours), medium (months), and long (years) time scales have been explored. We detected 303 distinct X-ray sources by analysing six EPIC/pn observations; 194 of them are members of the cluster. Stars of all spectral types, from the early-types to the late-M dwarfs, were detected.
