Investigating coronal saturation and supersaturation in fast-rotating M-dwarf stars
At 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 …
