The nine M-dwarfs in the Hyades Cluster which were detected as X-ray sources by the EINSTEIN Observatory have been observed with the VLA at 6 cm; only upper limits to the microwave emission were obtained (~0.1–0.2 mJy). However, a recent rotational velocity study of these stars using the MMT and an argument that cool, dark regions must necessarily exist on these stars, enables us to compare these Hyades M-dwarfs to other radio and X-ray active M-dwarfs.
