X-ray emission is ubiquitously found for hot and cool stars in the HR-diagram. The X-ray emission from hot stars is thought to be related to radiative wind instabilities, that of cool stars to magnetic activity, produced by the dynamo mechanism in the outer convection zones. B/A-tye stars without winds and outer convection zones should then be devoid of X-ray emission, yet one does find some percentage of those stars as X-ray emitters. This X-ray emission is conventionally attributed to low-mass companions.We show that the stars HD66318 and HD215441 with extremely large magnetic fields (> 10kG) are X-ray sources and suspect that all B/A-type stars with sufficiently strong field are X-ray emitters. We thus propose to carry out a survey of B/A-type with very strong measured magnetic fields.
