000005154 520__ $$aWe present an analysis of the TESS-based light curve of the chemically         peculiar A-type (Ap) star 21 Com (HD 108945). We used the simple         aperture photometry light curve with a time span of 27 days. A         least-squares fit to the data with 10 harmonics yields a         frequency of 0.48726 day$^{-1}$, which corresponds to a         rotational period of 2.05229 days. Furthermore, we find no         evidence of any short-term variability beyond the pure         rotational signature.
