Optical Observations of Trans-Neptunian and Centaur Objects

, 2000
Trans-Neptunian objects are probably primitive remnants from the early accretional phases of the solar system and may contain the most pristine unprocessed material.

Primordial Orbital Alignment of Sednoids

The Astrophysical Journal Letters
We examined the past history of the three most detached trans-Neptunian objects (TNOs)—Sedna, 2012 VP _113 , and Leleakuhonua (2015 TG _387 )—the three clearest members of the dynamical class known as sednoids, with high perihelia distances q .

A carefully characterised trans-neptunian survey

, 2015
The Trans-Neptunian objects (TNOs) preserve evidence of planet building processes in their orbital and size distributions. While all populations show steep size distributions for large objects, recently a relative deficit of Neptunian Trojans and ...

Historical Surveys to Rubin First Look: Absolute Colors of Trans-Neptunian Objects

The Planetary Science Journal
We present a comprehensive photometric study of trans-Neptunian objects (TNOs) by combining data from the Sloan Digital Sky Survey, the Colours of the Outer Solar System Origins Survey, the Dark Energy Survey, and the recent Rubin First Look (RFL) data ...

Nitrogen-bearing Species on Trans-Neptunian Objects Revealed by JWST/DiSCo-TNOs

The Astrophysical Journal
C≡N-bearing species are valuable tracers of nitrogen chemistry in the solar system. Ranging from volatile compounds like HCN and CH _3 CN in cometary comae to refractory CN-bearing organics in some micrometeorites and interplanetary dust particles, these

Can Neptune’s Distant Mean Motion Resonances Constrain Undiscovered Planets in the Solar System? Lessons from a Case Study of the 9:1 Resonance

The Planetary Science Journal
Recent observational surveys of the outer solar system provide evidence that Neptune's distant n :1 mean motion resonances may harbor relatively large reservoirs of trans-Neptunian objects (TNOs). In particular, the discovery of two securely classified 9:

Irregular Moons Possibly Injected from the Outer Solar System by a Stellar Flyby

The Astrophysical Journal Letters
The irregular moons orbit the giant planets on distant, inclined, and eccentric trajectories, in sharp contrast with the coplanar and quasicircular orbits of the regular moons.
