The delta Scuti variability of three stars with Ap spectral classifications, HR 151, 239, and 7461.
Abstract
Observations which show HR 151 and 7461 to be Delta Scuti stars and which confirm the Delta Scuti variability of HR 239 are presented. All three of these stars have been classified as Ap stars by at least one spectroscopist, but those classifications are insecure and need to be re-examined. If any of these stars are really magnetic Ap stars, then their Delta Scuti variability is of considerable interest.
