Properties of X-ray activity cycles on young solar-like stars: epsilon Eridanae
收藏资源简介：
We propose to continue our XMMNewton monitoring of the young, solar analogepsEri with the aim to understand dynamo cycles in the early life of the Sun.XMMNewton has recently detected an Xray cycle in another young solar analog,iota Hor, displaying cycle characteristics suggesting violent activity of theSun at an age of virgul600 Myr. Such behavior may affect the evolution of planetatmospheres. To verify if the pecularities of the cycle on iotaHor are typicalfor the dynamos on such young stars we intend to search for the Xray cycle ofepsEri, the second youngest star with known CaII cycle (Pcyc virgul 3.0yrs). We askhere for two snapshots (2 x 5 ksec), which we will combine with the previouslyexecuted or scheduled observations from our AO14 and AO15 programs. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
