Scientific paper

We propose to observe four M-type giants detected in the course of the ROSAT all-sky survey in order to confirm the detections, to obtain accurate positions and count rates, and to explore possible X-ray variability with the HRC-I. M-type giants are old, low-mass stars to the right of the X-ray dividing line and are not expected to show magnetic activity and hence X-ray emission at all. Any X-ray detections among such stars would challenge our ideas of coronal structures and late stellar activity in giants, since possible companions are not a reasonable explanation. While two such stars have already been confirmed as X-ray sources with Chandra in AO2, observations of the remaining stars are important to determine the fraction of active M-type giants.
