摘要：
The X-ray properties of A stars are reviewed and their X-ray generating mechanisms discussed. A-type stars bridge the regimes of cool and hot stars and exhibit diverse high-energy features; in particular, among A stars are found the hottest magnetically active stars as well as the coolest wind-shock stars. In the domain of late A-type stars X-ray emission is related to the presence of coronae, while in Ap/Bp stars a magnetically channelled wind-shock model is applicable.
