Giga-year evolution of Jupiter Trojans and the asymmetry problem [PDF]
Icarus, 2014 We present a series of numerical integrations of observed and fictitious Jupiter Trojan asteroids, under the gravitational effects of the four outer planets, for time-spans comparable with the age of the Solar System. From these results we calculate the escape rate from each Lagrange point, and construct dynamical maps of "permanence" time in different

The impact history and prolonged magmatism of the angrite parent body
Meteoritics &Planetary Science, Volume 59, Issue 1, Page 23-39, January 2024.Abstract As some of the oldest differentiated materials in our solar system, angrite meteorites can provide unique insights into the earliest stages of planetary evolution. However, the timing of planetary mixing, as evidenced by oxygen isotope variations in the quenched angrites, and the extent of magmatism on the angrite parent body (APB) remain ...

The Distribution of Highly Red-sloped Asteroids in the Middle and Outer Main Belt
The Planetary Science JournalRed ( S > 10%/0.1 μ m) spectral slopes are common among Centaurs and trans-Neptunian objects (TNOs) in the outer solar system. Interior to and co-orbital with Jupiter, the red ( S ∼ 10%/0.1 μ m) slopes of D-type main-belt and Jupiter Trojan asteroids are

Prospects of a New L5 Trojan Flyby Target for the Lucy Mission
The Planetary Science JournalNASA’s Lucy spacecraft is en route to conduct the first close encounter with Jupiter’s Trojans. While most scheduled flybys lie in the L _4 cloud, the only L _5 target is the Patroclus–Menoetius binary. Since each flyby offers unique insights into target

Collisional Evolution of Jupiter Trojans
, 2023 Jupiter Trojans (JT) are asteroids that populate the Sun-Jupiter Lagrangian regions, L4 and L5, at a mean distance of about 5.2 au from the Sun. These asteroids are believed to be leftovers from the Solar System's early days and have been in stable orbits around Jupiter for billions of years.

Jupiter’s Metastable Companions
The Astrophysical Journal LettersJovian co-orbitals share Jupiter’s orbit and exhibit 1:1 mean-motion resonance with the planet. This includes >10,000 so-called Trojan asteroids surrounding the leading (L4) and trailing (L5) Lagrange points, viewed as stable groups dating back to planet

Size and Shape of Jupiter Trojan (2207) Antenor from Stellar Occultations
The Astronomical JournalLibrating around the Lagrange L5, the Jupiter’s Trojan (2207) Antenor has been observed in recent years and its rotational light curve suggests it to be a very likely binary asteroid candidate.

Lucy Mission Search Plans for Activity around Its Jovian Trojan Flyby Targets
The Planetary Science JournalActivity in small bodies, defined here as the episodic or continuous release of material, was long thought to be exclusively a behavior of comets, but it has since been discovered in some centaurs, main-belt asteroids, and near-Earth asteroids.

Lucy L′Ralph In-flight Calibration and Results at (152830) Dinkinesh
The Planetary Science JournalThe L’Ralph instrument is a key component of NASA’s Lucy mission, intended to provide spectral image data of multiple Jupiter Trojans. The instrument operates from ∼0.35 to 4 μ m using two focal plane assemblies: a 350–950 nm multispectral imager, Multi ...
