Properties of X-ray activity cycles on young solar-like stars\: epsilon Eridanae

We propose to continue our XMMNewton monitoring of the young solar analogepsilon Eri started in AO 14. So far only one Xray cycle has been found on astar resembling the young Sun, iota Hor (600Myr, SpT G0V). Its Xray cycle isremarkably one of the shortest dynamo cycles known to date (1.6 yrs), the onlyXray cycle identified so far on a star with high chromospheric activity level,and episodically interrupted. Our target, Epsilon Eri resembles iota Hor (youngage, short calcium cycle, high activity) and our observations aim atestablishing whether the peculiar features of iota Hor.s Xray cycle arecharacteristic for such young stars. We ask for two snapshots in AO17, for atotal of 10ksec to be combined with our previous data and the continued Ca II monitoring program of epsilon Eri. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
