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

Col-OSSOS: The Distribution of Surface Classes in Neptune's Resonances

The Planetary Science Journal, 2023
The distribution of surface classes of resonant trans-Neptunian objects (TNOs) provides constraints on the protoplanetesimal disk and giant planet migration.

Close Trans-Neptunian Object Passages as a Driver of the Origin and Evolution of Ultrawide Kuiper Belt Binaries

The Astronomical Journal, 2022
Within the dynamically cold low-inclination portion of the Classical Kuiper Belt, there exists a population of weakly bound binary systems with a number of unusual properties, most notable of which is their extremely wide orbital separations—beyond 7% of

On the application of machine learning in astronomy and astrophysics: A text‐mining‐based scientometric analysis

WIREs Data Mining and Knowledge Discovery, Volume 12, Issue 5, September/October 2022., 2022
This work presents a text‐mining‐based scientometric analysis of the scientific output in the last three decades regarding the use of artificial intelligence and machine learning in the fields of astronomy and astrophysics. Abstract Since the beginning of the 21st century, the fields of astronomy and astrophysics have experienced significant growth at ...

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.

Are there long‐living Hilda‐like asteroids between Jupiter and Saturn?

Astronomische Nachrichten, Volume 343, Issue 6-7, July-August., 2022
Abstract To clarify the question of asteroids between Jupiter and Saturn a numerical study of the stability of orbits of fictitious bodies in this region has been undertaken. There are almost no minor planets moving there with the exception of 61 faint asteroids.

A Dynamical Survey of the Trans-Neptunian Region. I. Mean-motion Resonances with Neptune

The Astrophysical Journal Supplement Series, 2023
In this paper, we present a large-scale dynamical survey of the trans-Neptunian region, with particular attention to mean-motion resonances (MMRs). We study a set of 4121 trans-Neptunian objects (TNOs), a sample far larger than in previous works.

The Geophysical Environment of (486958) Arrokoth—A Small Kuiper Belt Object Explored by New Horizons

Journal of Geophysical Research: Planets, Volume 127, Issue 6, June 2022., 2022
Abstract NASA's New Horizons mission performed the first flyby of a small Kuiper Belt Object (KBO), (486958) Arrokoth on 1 January 2019. The fast flyby revealed a fascinating, flattened, contact binary replete with a variety of unexpected geologic terrains.

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.
