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.

Spectrophotometry of Trans-Neptunian Objects
, 2000 International audienceThe Trans-Neptunian Objects (TNOs) are very difficult to observe due to their faintness. Spectra can be obtained for only few objects.

Spectrophotometry of Trans-Neptunian Objects [PDF]
Highlights of Astronomy, 2002 AbstractThe Trans-Neptunian Objects (TNOs) are very difficult to observe due to their faintness. Spectra can be obtained for only few objects. For this reason, broad band photometry is the only available technique to study their physical properties from a statistical point of view.

Col-OSSOS: Evidence for a Compositional Gradient Inherited from the Protoplanetary Disk?
The Planetary Science Journal, 2023 In the present-day Kuiper Belt, the number of compositional classes and the orbital distributions of these classes hold important cosmogonic implications for the solar system.

Colors and taxonomy of Centaurs and trans-Neptunian objects [PDF]
Astronomy and Astrophysics, 2010 The study of the surface properties of Centaurs and Trans-Neptunian Objects (TNOs) provides essential information about the early conditions and evolution of the outer Solar System. Due to the faintness of most of these distant and icy bodies, photometry currently constitutes the best technique to survey a statistically significant number of them.

Study of Dynamical Evolution of Pairs of Trans-Neptunian Objects [PDF]
, 2020 Based on the analysis of Kolshevnikov’s metrics, pairs of trans-Neptunian objects in close orbits are identified. Performing a numerical study in the field of trans-Neptunian objects in the past over a time interval of 10 million years.

Volatile evolution and atmospheres of Trans-Neptunian objects [PDF]
, 2020 At 30-50 K, the temperatures typical for surfaces in the Kuiper Belt (e.g. Stern & Trafton 2008), only seven species have sublimation pressures higher than 1 nbar (Fray & Schmitt 2009): Ne, N$_2$, CO, Ar, O$_2$, CH$_4$, and Kr. Of these, N$_2$, CO, and CH$_4$ have been detected or inferred on the surfaces of Trans-Neptunian Objects (TNOs).

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 ...

Modeling Long-Term Photometric Data of Trans-Neptunian Objects and Centaurs
Frontiers in Astronomy and Space Sciences, 2022 Trans-Neptunian objects and Centaurs are small Solar System bodies that reside in the outer parts of the Solar System. These objects present photometric behaviors that are influenced due to a change in their aspect angle.

Compositional study of trans-Neptunian objects at λ > 2.2 μm
, 2021 Using data from the Infrared Array Camera on the Spitzer Space Telescope, we present photometric observations of a sample of 100 trans-Neptunian objects (TNOs) beyond 2.2 μm.
