Abstract:
    The tenth part of the OGLE-III Catalog of Variable Stars contains 125
    Double Periodic Variables (DPVs) from the Large Magellanic Cloud. DPVs
    are semi-detached binaries which show additional variability with a
    period around 33 times longer than the orbital period. The cause of
    this long cycle is not known and previous studies suggest it involves
    circumbinary matter.
