Light Curves of Trans-Neptunian Objects from the K2 Mission of the Kepler Space Telescope

The Astrophysical Journal Supplement Series, 2023
The K2 mission of the Kepler Space Telescope allowed the observations of light curves of small solar system bodies throughout the whole solar system. In this paper, we present the results of a collection of K2 trans-Neptunian object observations between ...

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 ...

Rotational properties of Centaurs and Trans-Neptunian Objects [PDF]

Astronomy & Astrophysics, 2008
Context. The knowledge of the rotational periods of the small bodies in the outer Solar System is a useful tool for retrieving information on the internal structure of the observed objects and for having hints on the collisional evolution state of the whole population. Aims.

Trans-Neptunian Object Colors as Evidence for a Past Close Stellar Flyby to the Solar System

The Astrophysical Journal Letters
Thousands of small bodies, known as trans-Neptunian objects (TNOs), orbit the Sun beyond Neptune. TNOs are remnants of the planets’ formation from a disk of gas and dust, so it is puzzling that they move mostly on eccentric orbits inclined to the ...

Raman analysis of organic refractory materials after energetic processing: Evidence for amorphous carbon on TNOs and comets

Meteoritics &Planetary Science, Volume 61, Issue 8, Page 1994-2015, August 2026.
Abstract Amorphous carbon (αC) is found in various extraterrestrial particles, including those thought to originate from the outer Solar System. αC can form through two main processes involving C‐rich materials: exposure to energetic charged particles and thermal processing.

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)

Orbital features of distant trans-Neptunian objects induced by giant gaseous clumps

, 2020
Context. The discovery of distant trans-Neptunian objects has led to heated discussions about the structure of the outer Solar System. Aims. We study the dynamical evolution of small bodies from the Hill regions of migrating giant gaseous clumps that ...

Defining soil: Proposals of zero‐states, active layer, and págousols (from ice parent materials) to fundamentally expand soil science

Soil Science Society of America Journal, Volume 90, Issue 2, March/April 2026.
Abstract Recent publications in soil science have reopened discussions over how soil and soil science should be defined, reflecting productive tension between historical constructs and the evolving frontiers of the discipline. While new definitions offered over the past decade provide valuable perspectives, they inevitably rely on past conventions and ...
