Modeling the disintegration of binary trans-Neptunian objects [PDF]

, 2022
We simulated the disintegration of binary trans-Neptunian objects with a mass of 10−10 solar masses at the component mass ratios: 1:1, 1:2, 1:10 without taking into account tidal effects.

Taxonomy of Centaurs and Trans-Neptunian Objects [PDF]

The Astronomical Journal, 2005
Trans-Neptunian objects (TNOs) and Centaurs display the widest color diversity in comparison to other small solar system bodies. The investigation of their properties can help in understanding the evolution of these objects. In this paper we propose a classification scheme based on multivariate statistical analysis of a homogeneous, high-quality set of

Steeper Scattered Disks Buckle Faster

The Astrophysical Journal Letters, 2023
Disks of low-mass bodies scattered by giant planets to large semimajor axis and constant periapsis orbits are vulnerable to a buckling instability. This instability exponentially grows orbital inclinations, raises periapsis distances, and coherently ...

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 ...

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)

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 ...

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 ...

Production of Oxidants by Ion Bombardment of Icy Moons in the Outer Solar System

Advances in Astronomy, Volume 2011, Issue 1, 2011., 2011
Our groups in Brazil, France and Italy have been active, among others in the world, in performing experiments on physical‐chemical effects induced by fast ions colliding with solids (frozen gases, carbonaceous and organic materials, silicates, etc.) of astrophysical interest. The used ions span a very large range of energies, from a few keV to hundreds
