Scientific paper

The long term photometric activity of DH Leonis has been compared with the predictions of Applegate's theory that magnetic cycles cause luminosity variation due entirely to temperature variations. Observations show that DH Leo is bluer when it is brighter but it is found that the slope Δ(B - V)/ΔV is not different from the main sequence slope, which indicates that radius change can not be ruled out.
