A study of the high-inclination population in the Kuiper belt -- IV. High-order mean motion resonances in the classical region
Jian Li, S. M. Lawler, Hanlun Lei
In our previous study of Neptune's 4:7 mean motion resonance (MMR), we discovered that its resonant angle can only librate within a specific eccentricity () versus inclination (…
OSSOS: XXVII. Population Estimates for Theoretically Stable Centaurs Between Uranus and Neptune
Rosemary C. Dorsey, Michele T. Bannister, Samantha M. Lawler +1
We calculate the upper bounds of the population of theoretically stable Centaur orbits between Uranus and Neptune. These small bodies are on low-eccentricity, low-inclination orbit…
OSSOS XXV: Large Populations and Scattering-Sticking in the Distant Transneptunian Resonances
B. L. Crompvoets, S. M. Lawler, K. Volk +8
There have been 77 TNOs discovered to be librating in the distant transneptunian resonances (beyond the 2:1 resonance, at semimajor axes greater than 47.7~AU) in four well-characte…
Visibility Predictions for Near-Future Satellite Megaconstellations: Latitudes near 50 Degrees will Experience the Worst Light Pollution
S. M. Lawler, A. C. Boley, H. Rein
Megaconstellations of thousands to tens of thousands of artificial satellites (satcons) are rapidly being developed and launched. These satcons will have negative consequences for…
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…
Collision Probabilities in the Edgeworth-Kuiper belt
Abedin Y. Abedin, JJ Kavelaars, Sarah Greenstreet +8
Here, we present results on the intrinsic collision probabilities, , and range of collision speeds, , as a function of the heliocentric distance, , in the trans-Neptu…
ALMA imaging of the M-dwarf Fomalhaut C's debris disc
Patrick F. Cronin-Coltsmann, Grant M. Kennedy, Paul Kalas +9
Fomalhaut C (LP 876-10) is a low mass M4V star in the intriguing Fomalhaut triple system and, like Fomalhaut A, possesses a debris disc. It is one of very few nearby M-dwarfs known…
OSSOS: The Eccentricity and Inclination Distributions of the Stable Neptunian Trojans
Hsing Wen Lin, Ying-Tung Chen, Kathryn Volk +10
The minor planets on orbits that are dynamically stable in Neptune's 1:1 resonance on Gyr timescales were likely emplaced by Neptune's outward migration. We explore the intrinsic l…
OSSOS XVIII: Constraining migration models with the 2:1 resonance using the Outer Solar System Origins Survey
Ying-Tung Chen, Brett Gladman, Kathryn Volk +13
Resonant dynamics plays a significant role in the past evolution and current state of our outer Solar System. The population ratios and spatial distribution of Neptune's resonant p…
Planetary Astronomy-Understanding the Origin of the Solar System
S. M. Lawler, A. C. Boley, M. Connors +9
There is a vibrant and effective planetary science community in Canada. We do research in the areas of meteoritics, asteroid and trans-Neptunian object orbits and compositions, and…
Perspectives on the distribution of orbits of distant Trans-Neptunian Objects
JJ Kavelaars, Samantha M. Lawler, Michele T. Bannister +1
Looking at the orbits of small bodies with large semimajor axes, we are compelled to see patterns. Some of these patterns are noted as strong indicators of new or hidden processes…
OSSOS XV: Probing the Distant Solar System with Observed Scattering TNOs
Nathan A. Kaib, Rosemary Pike, Samantha Lawler +6
Most known trans-Neptunian objects (TNOs) gravitationally scattering off the giant planets have orbital inclinations consistent with an origin from the classical Kuiper belt, but a…
OSSOS: XIII. Fossilized Resonant Dropouts Tentatively Confirm Neptune's Migration was Grainy and Slow
S. M. Lawler, R. E. Pike, N. Kaib +8
The migration of Neptune's resonances through the proto-Kuiper belt has been imprinted in the distribution of small bodies in the outer Solar System. Here we analyze five published…
OSSOS. VII. 800+ trans-Neptunian objects - the complete data release
Michele T. Bannister, Brett J. Gladman, J. J. Kavelaars +33
The Outer Solar System Origins Survey (OSSOS), a wide-field imaging program in 2013-2017 with the Canada-France-Hawaii Telescope, surveyed 155 deg of sky to depths of $m_r =…
OSSOS. VIII. The Transition Between Two Size Distribution Slopes in the Scattering Disk
S. M. Lawler, C. Shankman, JJ. Kavelaars +9
The scattering trans-Neptunian Objects (TNOs) can be measured to smaller sizes than any other distant small-body population. We use the largest sample yet obtained, 68 discoveries,…
OSSOS IX: two objects in Neptune's 9:1 resonance -- implications for resonance sticking in the scattering population
Kathryn Volk, Ruth A. Murray-Clay, Brett J. Gladman +12
We discuss the detection in the Outer Solar System Origins Survey (OSSOS) of two objects in Neptune's distant 9:1 mean motion resonance at semimajor axis ~au. Both ob…
OSSOS: X. How to use a Survey Simulator: Statistical Testing of Dynamical Models Against the Real Kuiper Belt
S. M. Lawler, JJ. Kavelaars, M. Alexandersen +4
All surveys include observational biases, which makes it impossible to directly compare properties of discovered trans-Neptunian Objects (TNOs) with dynamical models. However, by c…
