Observations of X-ray oscillations in xi Boo: evidence of a fast-kink mode in the stellar loops.

PANDEY J.C. and SRIVASTAVA A.K.

Abstract (from CDS):

We report the observations of X-ray oscillations during the flare in a cool active star xi Boo for the first time. xi Boo was observed by EPIC/MOS of the XMM-Newton satellite. The X-ray light curve is investigated with wavelet and periodogram analyses. Both analyses clearly show oscillations of the period of ∼1019 s. We interpret these oscillations as a fundamental fast-kink mode of magnetoacoustic waves.
