Scientific paper

Beta Ceti (HD 4128) is the brightest K giant as seen in X-rays. This K0 III post helium flash star is unusually luminous in X-rays compared to other clump giants. The high X-ray luminosity may be due to its age or to a rejuvenated dynamo as a result of angular momentum redistribution in its core. We propose a deep (88 ks) HETG observation to measure the coronal temperature structure, coronal densities, and coronal abundances of this unusual star.
