A low-inclination neutral Trans-Neptunian Object in a extreme orbit
Ying-Tung Chen, Marielle R. Eduardo, Marco A. Muñoz-Gutiérrez +3
We present photometric observations and numerical simulations of 2016 SD, a low inclination () extreme trans-Neptunian Object with a large semi-major axis ($…
Col-OSSOS: Probing Ice Line/Color Transitions within the Kuiper Belt's Progenitor Populations
Laura E. Buchanan, Megan E. Schwamb, Wesley C. Fraser +15
Dynamically excited objects within the Kuiper belt show a bimodal distribution in their surface colors, and these differing surface colors may be a tracer of where these objects fo…
FOSSIL: I. The Spin Rate Limit of Jupiter Trojans
Chan-Kao Chang, Ying-Tung Chen, Wesley C. Fraser +25
Rotation periods of 53 small (diameters km) Jupiter Trojans (JTs) were derived using the high-cadence light curves obtained by the FOSSIL phase I survey, a Subaru/Hype…
Long-term Dynamical Stability in the Outer Solar System I: The Regular and Chaotic Evolution of the 34 Largest Trans-Neptunian Objects
M. A. Muñoz-Gutiérrez, A. Peimbert, M. J. Lehner +1
We carried out an extensive analysis of the stability of the outer solar system, making use of the frequency analysis technique over short-term integrations of nearly a hundred tho…
Col-OSSOS: The Distinct Colour Distribution of Single and Binary Cold Classical KBOs
Wesley C. Fraser, Susan D. Benecchi, JJ Kavelaars +11
The cold classical Kuiper Belt Objects (KBOs) possess a high, binary fraction. Widely separated and dynamically fragile, these binary systems have been useful in trac…
Col-OSSOS: Color and Inclination are Correlated Throughout the Kuiper Belt
Michael Marsset, Wesley C. Fraser, Rosemary E. Pike +12
Both physical and dynamical properties must be considered to constrain the origins of the dynamically excited distant Solar System populations. We present high-precision (g-r) colo…
Colors of Centaurs observed by the Subaru/Hyper Suprime-Cam and implications for their origin
Haruka Sakugawa, Tsuyoshi Terai, Keiji Ohtsuki +4
Centaurs have orbits between Jupiter and Neptune and are thought to originate from the trans-Neptunian region. Observations of surface properties of Centaurs and comparison with th…
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…
All planetesimals born near the Kuiper Belt formed as binaries
Wesley C. Fraser, Michele t. Bannister, Rosemary E. Pike +19
The cold classical Kuiper belt objects have low inclinations and eccentricities and are the only Kuiper belt population suspected to have formed in situ. Compared with the dynamica…
Multi-band Photometry of Trans-Neptunian Objects in the Subaru Hyper Suprime-Cam Survey
Tsuyoshi Terai, Fumi Yoshida, Keiji Ohtsuki +7
We present a visible multi-band photometry of trans-Neptunian objects (TNOs) observed by the Subaru Telescope in the framework of Hyper Suprime-Cam Subaru Strategic Program (HSC-SS…
OSSOS: V. Diffusion in the orbit of a high-perihelion distant Solar System object
Michele T. Bannister, Cory Shankman, Kathryn Volk +12
We report the discovery of the minor planet 2013 SY, on an exceptionally distant, highly eccentric orbit. With a perihelion of 50.0 au, 2013 SY's orbit has a semi-maj…
Discovery of A New Retrograde Trans-Neptunian Object: Hint of A Common Orbital Plane for Low Semi-Major Axis, High Inclination TNOs and Centaurs
Ying-Tung Chen, Hsing Wen Lin, Matthew J. Holman +14
Although the majority of Centaurs are thought to have originated in the scattered disk, with the high-inclination members coming from the Oort cloud, the origin of the high inclina…
OSSOS: IV. Discovery of a dwarf planet candidate in the 9:2 resonance with Neptune
Michele T. Bannister, Mike Alexandersen, Susan D. Benecchi +32
We report the discovery and orbit of a new dwarf planet candidate, 2015 RR, by the Outer Solar System Origins Survey (OSSOS). 2015 RR's orbit is eccentric ($e=0.586…
The Outer Solar System Origins Survey: I. Design and First-Quarter Discoveries
Michele T. Bannister, J. J. Kavelaars, Jean-Marc Petit +36
We report the discovery, tracking and detection circumstances for 85 trans-Neptunian objects (TNOs) from the first 42 deg of the Outer Solar System Origins Survey (OSSOS). Th…
Automated differential photometry of TAOS data: preliminary analysis
D. Ricci, P. -G. Sprimont, C. Ayala +8
A preliminary data analysis of the stellar light curves obtained by the robotic telescopes of the TAOS project is presented. We selected a data run relative to one of the stellar f…
The TAOS Project: Upper Bounds on the Population of Small KBOs and Tests of Models of Formation and Evolution of the Outer Solar System
F. B. Bianco, Z. -W. Zhang, M. J. Lehner +23
We have analyzed the first 3.75 years of data from TAOS, the Taiwanese American Occultation Survey. TAOS monitors bright stars to search for occultations by Kuiper Belt Objects (KB…
