    this news item was published in Nature magazine.

    the abstract is a bit dramatic-sounding:
    "A quadrillion previously unnoticed small bodies beyond Neptune have been spotted as they dimmed X-rays from a distant source. Models of the dynamics of debris in the Solar System's suburbs must now be reworked."

    the news article refers to a technical paper by H-K Chang et al, also to be published in Nature (issue number 442).

    I suspect that the lead author H-K Chang is Hsiang-Kuang Chang

    I cannot find the technical article to be published in Nature

    a link is given to the "Taiwan Occultation Survey"
