Alignment in star-debris disc systems seen by Herschel
J. S. Greaves, G. M. Kennedy, N. Thureau +28
Many nearby main-sequence stars have been searched for debris using the far-infrared Herschel satellite, within the DEBRIS, DUNES and Guaranteed-Time Key Projects. We discuss here…
Limits on Quaoar's Atmosphere
Wesley C Fraser, Chad Trujillo, Andrew W. Stephens +4
Here we present high cadence photometry taken by the Acquisition Camera on Gemini South, of a close passage by the km radius Kuiper Belt Object, (50000) Quaoar, of a r'=2…
On a Possible Size/Color Relationship in the Kuiper Belt
R. E. Pike, J. J. Kavelaars
Color measurements and albedo distributions introduce non-intuitive observational biases in size-color relationships among Kuiper Belt Objects (KBOs) that cannot be disentangled wi…
Kuiper Belt Occultation Predictions
Wesley C. Fraser, Stephen Gwyn, Chad Trujillo +13
Here we present observations of 7 large Kuiper Belt Objects. From these observations, we extract a point source catalog with precision, and astrometry of our target Kui…
A Uranian Trojan and the frequency of temporary giant-planet co-orbitals
Mike Alexandersen, Brett Gladman, Sarah Greenstreet +3
Trojan objects share a planet's orbit, never straying far from the triangular Lagrangian points, 60 degrees ahead of (L4) or behind (L5) the planet. We report the detection of a Ur…
