Causal evidence for the primordiality of colours in trans-Neptunian objects. [PDF]

Mon Not R Astron Soc Lett
ABSTRACT The origins of the colours of trans-Neptunian objects (TNOs) represent a crucial unresolved question, central to understanding the history of our Solar system. Recent observational surveys revealed correlations between the eccentricity and inclination of TNOs, and their colours. This rekindled the long-standing debate on whether

Dynamic Evolution of Pairs of Trans-Neptunian Objects: the Case of Binary and Single Objects in Pair [PDF]

, 2021
We performed a search for pairs of trans-Neptunian objects in close orbits with semi-ma jor axes of more than 30 AU. Distances in the space of Keplerian orbits were estimated using the Kholshevnikov metrics.

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.

Trans–Neptunian objects' surface properties [PDF]

Proceedings of the International Astronomical Union, 2005
Recent observations in visible photometry have provided B, V, R and I high quality colors for more than 130 objects. Color diversity is now a reality in the TNOs population. Relevant statistical analyses have been performed and all possible correlations between optical colors and orbital parameters have been analyzed.

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 [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.

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.

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).

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 ...
