Light curve changes and possible precession in mCP stars.

PYPER D.M. and ADELMAN S.J.

Abstract (from CDS):

We searched for evidence of precession in mCP stars observed with the Four College Automatic Photometric Telescope. We were able to improve the periods of six of these stars. We also found some evidence for precession over time intervals of decades in six or possibly seven of these stars, however, the evidence is not strong. To provide better evidence for precession, yearly observations with complete phase coverage over a time interval of at least two decades would be required.
