Title: An Oort cloud origin for the high-inclination, high-perihelion Centaurs
Authors: R. Brasser, M. E. Schwamb, P. S. Lykawka, R. S. Gomes

We analyse the origin of three Centaurs with perihelia in the range 15 AU to 30 AU, inclinations above 70 deg and semi-major axes shorter than 100 AU. Based on long-term numerical simulations we conclude that these objects most likely originate from the Oort cloud rather than the Kuiper Belt or Scattered Disc. We estimate that there are currently between 1 and 200 of these high-inclination, high-perihelion Centaurs with absolute magnitude H<8.
