cds-question@unistra.frglobular-star-clustersdwarf-starsm-starsx-ray-sourcesAt fast rotation rates, the coronal activity of G- and K-type stars has been observed to "saturate" and then decline again at even faster rotation rates - a phenomenon dubbed "supersaturation". In this paper, we investigate coronal activity in fast-rotating M-dwarfs using deep XMM-Newton observations of 97 low-mass stars of known rotation period in the young open cluster NGC 2547 and combine these with published X-ray surveys of low-mass field and cluster stars of known rotation period.2011MNRAS.411.2099Jhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/411/2099CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/335/291 : BVI photometry of NGC 2547 (Naylor+, 2002)J/MNRAS/383/1588 : VIc photometry of NGC 2547 low-mass stars (Irwin+, 2008)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/411/2099https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/411/2099http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/411/2099https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/411/2099https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/411/2099http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/411/2099GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/411/2099/table1 (X-ray detections of sources in the Irwin et al.
