Query: KUV 01584-0939: A Helium-transferring Cataclysmic Variable with an
  Orbital Period of 10 Minutes   High speed photometry of KUV 01584-0939 (alias Cet3) shows that is has a
period of 620.26 s. Combined with its hydrogen-deficient spectrum, this implies
that it is an AM CVn star. The optical modulation is probably a superhump, in
which case the orbital period will be slightly shorter than what we have
observed.
