| 内容記述 | CCD photometry of KO Vel obtained on five nights in April 1987 is reported. From this and the two previously published sets of CCD photometry, a new candidate orbital period of 0.422 d (10.12 h) is derived. The shape of the folded light curve is nonsinusoidal, which has made the Fourier transform method less effective than usual. It is shown that all three sets of light curves examined here are consistent with the proposed period. All three data sets for the presence of a shorter period are examined, and no conclusive evidence for a periodic variation on an approximately 1 hr time scale is found. The nature of KO Vel therefore still remains an open question. |
