Optimized Herschel/PACS photometer observing and data reduction strategies for moving solar system targets [PDF]

, 2013
The "TNOs are Cool!: A survey of the trans-Neptunian region" is a Herschel Open Time Key Program that aims to characterize planetary bodies at the outskirts of the Solar System using PACS and SPIRE data, mostly taken as scan-maps.

An Outer Planet Beyond Pluto and Origin of the Trans-Neptunian Belt Architecture

, 2007
Trans-Neptunian objects (TNOs) are remnants of a collisionally and dynamically evolved planetesimal disk in the outer solar system. This complex structure, known as the trans-Neptunian belt (or Edgeworth-Kuiper belt), can reveal important clues about ...

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.

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 ...

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 ...

Discovery of A New Retrograde Trans-Neptunian Object: Hint of A Common Orbital Plane for Low Semi-Major Axis, High Inclination TNOs and Centaurs [PDF]

, 2016
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 inclination component of trans-Neptunian objects (TNOs) remains uncertain.

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.

High‐Order Analytic Expansion of Disturbing Function for Doubly Averaged Circular Restricted Three‐Body Problem

Advances in Astronomy, Volume 2016, Issue 1, 2016., 2016
Terms in the analytic expansion of the doubly averaged disturbing function for the circular restricted three‐body problem using the Legendre polynomial are explicitly calculated up to the fourteenth order of semimajor axis ratio (α) between perturbed and perturbing bodies in the inner case (α < 1), and up to the fifteenth order in the outer case (α > 1)

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 ...
