Pairs of Trans-Neptunian Objects with close orbits [PDF]

Астрономия и исследование космического пространства: Всероссийская с международным участием научная конференция студентов и молодых ученых, посвященная памяти Полины Евгеньевны Захаровой, 2021
A search for pairs of dynamically correlated trans-Neptunian objects with semi-major axes of more than 30 au was performed. The Kholshevnikov metrics in the space of Keplerian orbits are used. Found 27 pairs with metrics less than 0.07 au1/2, 22 pairs in which one of the components is binary, for metrics less than 0.12 au1/2, and 11 pairs of binary ...

Equilibrium Shapes of Large Trans-Neptunian Objects [PDF]

The Astrophysical Journal Letters, 2017
Abstract The large trans-Neptunian objects (TNO) with radii larger than 400 km are thought to be in hydrostatic equilibrium. Their shapes can provide clues regarding their internal structures that would reveal information on their formation and evolution.

Distribution Inference for Physical and Orbital Properties of Jupiter’s Moons

Advances in Astronomy, Volume 2018, Issue 1, 2018., 2018
According to the physical and orbital characteristics in Carme group, Ananke group, and Pasiphae group of Jupiter’s moons, the distributions of physical and orbital properties in these three groups are investigated by using one‐sample Kolmogorov–Smirnov nonparametric test.

Is There an Earth-like Planet in the Distant Kuiper Belt?

The Astronomical Journal, 2023
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 investigate the effects of a hypothetical Kuiper Belt planet (KBP) on the orbital ...

Dynamical Classification of Trans-Neptunian Objects Detected by the Dark Energy Survey [PDF]

Astronomical Journal, 2020
The outer solar system contains a large number of small bodies (known as trans-Neptunian objects or TNOs) that exhibit diverse types of dynamical behavior.

Rotations and densities of trans-Neptunian objects [PDF]

Astronomy & Astrophysics, 2009
Trans-Neptunian objects (TNOs) represent a new frontier in the study of our Solar System. In particular, the investigation of their rotational properties can provide important hints about their internal structure and collisional evolution. Aims: We expand the limited sample of TNOs with known rotation rates, and improve the knowledge of the physical ...

Optimal Trajectory Determination and Mission Design for Asteroid/Deep‐Space Exploration via Multibody Gravity Assist Maneuvers

International Journal of Aerospace Engineering, Volume 2017, Issue 1, 2017., 2017
This paper discusses the creation of a genetic algorithm to locate and optimize interplanetary trajectories using gravity assist maneuvers to improve fuel efficiency of the mission. The algorithm is implemented on two cases: (i) a Centaur‐class target close to the ecliptic plane and (ii) a Centaur‐class target with a high inclination to the ecliptic ...

Photometry of Outer Solar System Objects from the Dark Energy Survey. I. Photometric Methods, Light-curve Distributions, and Trans-Neptunian Binaries

The Astrophysical Journal Supplement Series, 2023
We report the methods of and initial scientific inferences from the extraction of precision photometric information for the >800 trans-Neptunian objects (TNOs) discovered in the images of the Dark Energy Survey (DES). Scene-modeling photometry is used to

Migration of trans-Neptunian objects to the Earth [PDF]

Astronomical & Astrophysical Transactions, 1999
AbstractMigration of trans–Neptunian objects under their mutual gravitation influence and the influence of the giant planets is investigated. These investigations are based on computer simulation results and on some formulas. We estimated that about 20 % of near–Earth objects with diameter d ≥ 1 km may have come from the Edgeworth–Kuiper belt.
