Col-OSSOS: z Band Photometry Reveals Three Distinct TNO Surface Types

Rosemary E. Pike, Wesley C. Fraser, Megan E. Schwamb +11

Several different classes of trans-Neptunian objects (TNOs) have been identified based on their optical and near-infrared colors. As part of the Colours of the Outer Solar System O…

A thermodynamic view of dusty protoplanetary disks

Min-Kai Lin, Andrew N. Youdin

Small solids embedded in gaseous protoplanetary disks are subject to strong dust-gas friction. Consequently, tightly-coupled dust particles almost follow the gas flow. This near co…

Rotation of Cometary Nuclei: New Lightcurves and an Update of the Ensemble Properties of Jupiter-Family Comets

R. Kokotanekova, C. Snodgrass, P. Lacerda +6

We report new lightcurves and phase functions for nine Jupiter-family comets (JFCs). They were observed in the period 2004-2015 with various ground telescopes as part of the Survey…

OSSOS VI. Striking Biases in the detection of large semimajor axis Trans-Neptunian Objects

Cory Shankman, JJ Kavelaars, Michele Bannister +9

The accumulating, but small, set of large semi-major axis trans-Neptunian objects (TNOs) shows an apparent clustering in the orientations of their orbits. This clustering must eith…
