Kuiper Belt Objects Photometry

Scientific paper

We present R- and V-band rotational light curves for classical Kuiper belt object 1997 CV29. The imaging data was obtained from the Canada-France-Hawaii Telescope (CFHT) archive located at the Canadian Astronomical Data Center (CADC). The data consist of one nights observations of a series of 42, 8 minute exposures in R band followed by 33, 8 minute exposures in V band acquired on the following night. Using relative photometry we determined a highly significant variation in the brightness of 1997 CV29. Using phase-dispersion-minimization we find 8.0, 11.2, and 15.8 hrs to be the most likely, periods of rotation and we argue that the ~16 hr period is the most likely based on our limited observing window. The phased light curve has a peak-to-peak range of Δm>~0.4+/-0.1 mag suggesting an axial ratio of a/b>~1.45.
