Abstract

17 Ap stars have been observed in the J, K, L and M infrared photometric wavebands. Excesses previously reported for three of the stars at a wavelength of 5 µm are not confirmed, but a possible excess is reported for one of the 17 stars. Such limited evidence for infrared excesses in Ap stars requires further study with more stars and at longer wavelengths.
