Observations of X-ray Oscillations in Ξ Boo: Evidence of Fast Kink Mode in the Stellar Loops
نویسندگان
چکیده
We report the observations of X-ray oscillations during the flare in a cool active star ξ Boo for the first time. ξ Boo was observed by EPIC/MOS of 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. Subject headings: stars: activity – stars: coronae – stars: flare – (magnetohydrodynamics:) MHD – waves

A coronal loop can be oscillated in various directions. A basic type of coronal loop oscillation is called transverse oscillation that can be caused by different factors, such as nearby active regions and flares. The damping of transverse oscillation may be produced by the dissipation mechanism or the wake of the traveling disturbance. The aim of this paper is to estimate the damping time of tr...

Transversal oscillation of coronal loops that are interpreted as signatures of magneto hydrodynamics (MHD) waves are observed frequently in active region corona loops. The amplitude of this oscillation has been found to be strongly attenuated. The damping of transverse oscillation may be produced by the dissipation mechanism and the wake of the traveling disturbance. The damping of transversal ...

We investigate the influence of longitudinal structuring on the fast kink modes of the coronal loops oscillations. Using a simple longitudinal exponential density structure, an analytical dispersion relation is derived. The properties of oscillatory periods and mode profiles and their deviations for such stratified structure are compared with those of the homogeneous tubes. Also, the effects of...
متن کاملForty Years of X-Ray Binaries
In 2012 it was forty years ago that the discovery of the first X-ray binary Centaurus X-3 became known. That same year it was discovered that apart from the High-Mass X-ray Binaries (HMXBs) there are also Low-Mass X-ray Binaries (LMXBs), and that Cygnus X-1 is most probably a black hole. By 1975 also the new class of Be/X-ray binaries was discovered. After this it took 28 years before ESAs INTE...
