Abstract (from CDS):

We report discovery of radial velocity variations in rare earth spectral lines of the roAp star 10 Aql with amplitudes of between 30 and 130 m s–1 and periods of about 11 min. Radial velocity variations with amplitude 70 m s –1 may also have been detected in one spectral line of Fe i in β CrB. If confirmed, our results may indicate that all Ap stars in a certain temperature range pulsate, which means that roAp stars do not exist as a separate class but are only distinguished by higher pulsational amplitudes.
