摘要：

We present a photometric study of 11 G-K dwarf members of the young open cluster surrounding a Persei, whose projected rotational velocities have indicated them to be rapid rotators. We detect significant rotational modulation due to surface inhomogeneities in 10 of the targets. We determine reliable axial rotation periods for six of these stars, using power spectrum analysis augmented with the CLEAN algorithm. Similar period analysis is also given for a further member whose power spectrum yielded ambiguous results.
