On the Long-Term Orbital Behaviour of Hilda Asteroids - I. Global Stability Patterns and Catalogue
Cristian F. Chavez, Jonathan Horner, Patryk Sofia Lykawka +2
The Hildas are objects trapped in 3:2 mean-motion resonance (MMR) with Jupiter, and are a fascinating window into the Solar system's formation and evolution. We present the results…
Kuiper Belt Formation via Grainy Planetary Migration
Patryk Sofia Lykawka, Jonathan Horner, Pedro Bernardinelli
We used N-body simulations to model the 4.5 Gyr orbital evolution of the early Kuiper Belt, incorporating a massive protoplanetary disk, the four giant planets, and 1500 primordial…
Discovery and dynamics of a Sedna-like object with a perihelion of 66 au
Ying-Tung Chen, Patryk Sofia Lykawka, Yukun Huang +30
Trans-Neptunian objects (TNOs) with large perihelion distances ( au) and semi-major axes ( au) provide insights into the early evolution of the solar system and th…
New Moons of Uranus and Neptune from Ultra-Deep Pencil Beam Surveys
Scott Sheppard, David Tholen, Marina Brozovic +4
We have conducted extremely ultra-deep pencil beam observations for new satellites around both Uranus and Neptune. Tens of images on several different nights in 2021, 2022 and 2023…
Formation of the four terrestrial planets in the Jupiter-Saturn chaotic excitation scenario: fundamental properties and water delivery
Patryk Sofia Lykawka, Takashi Ito
The Jupiter-Saturn chaotic excitation (JSCE) scenario proposes that the protoplanetary disk was dynamically excited and depleted beyond ~1-1.5 au in a few Myr, offering a new and p…
Is There an Earth-like Planet in the Distant Kuiper Belt?
Patryk Sofia Lykawka, Takashi Ito
The orbits of trans-Neptunian objects (TNOs) can indicate the existence of an undiscovered planet in the outer solar system. Here, we used N-body computer simulations to investigat…
Terrestrial planet and asteroid belt formation by Jupiter-Saturn chaotic excitation
Patryk Sofia Lykawka, Takashi Ito
The terrestrial planets formed by accretion of asteroid-like objects within the inner solar system's protoplanetary disk. Previous works have found that forming a small-mass Mars r…
Can narrow disks in the inner solar system explain the four terrestrial planets?
Patryk Sofia Lykawka
A successful solar system model must reproduce the four terrestrial planets. Here, we focus on 1) the likelihood of forming Mercury and the four terrestrial planets in the same sys…
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…
Solar System Physics for Exoplanet Research
J. Horner, S. R. Kane, J. P. Marshall +13
Over the past three decades, we have witnessed one of the great revolutions in our understanding of the cosmos - the dawn of the Exoplanet Era. Where once we knew of just one plane…
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…
Constraining the Formation of the Four Terrestrial Planets in the Solar System
Patryk Sofia Lykawka, Takashi Ito
To reproduce the orbits and masses of the terrestrial planets (analogs) of the solar system, most studies scrutinize simulations for success as a batch. However, there is insuffici…
"TNOs are Cool": A survey of the trans-Neptunian region XIV. Size/albedo characterization of the Haumea family observed with Herschel and Spitzer
E. Vilenius, J. Stansberry, T. Müller +14
A group of trans-Neptunian objects (TNO) are dynamically related to the dwarf planet 136108 Haumea. Ten of them show strong indications of water ice on their surfaces, are assumed…
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…
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 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…
