Summary[edit]
DescriptionXi Hydrae.jpg |
English: A computer-generated illustration of one possible non-radial oscillation mode in the giant star xi Hya. The blue parts contain particles in the upper stellar atmosphere moving away from the stellar centre, hence they cause a "blue-shift" (towards shorter wavelengths) in the spectrum for the observer. At the same time, particles in the red parts move towards the stellar centre and cause a "red-shift" (towards longer wavelengths). Particles in the white regions do not move during the oscillation cycle. Half an oscillation cycle later, the red parts will have become blue and vice versa. |
