Hybrid stars are giant stars that exhibit both chromospheric emission features and signatures of mass outflow, and hence provide a link between stars on either side of the ``Coronal Dividing Line". We have obtained long duration {\sl ROSAT} PSPC exposures of two nearby hybrid stars ($\alpha$ TrA and $\iota$ Aur), and here, we compare these observations with models of X-ray emission on giant stars.
