Abstract
A detailed search has been performed at 10.7 GHz for any pulsed radio emission from four X-ray pulsators (A0535+26, X Persei, AE Aquarii and H2252-035). The results obtained indicate no radio emission-pulsed or otherwise is present at a level of ≥ 50 mJy (two standard deviations upper limit). This value is considerably more sensitive than the previous studies carried out on these sources and presents problems in the understanding of compact, magnetised stellar objects.
