Pencil-Beam Surveys for Trans-Neptunian Objects: Limits on Distant Populations

Icarus, 2010
Two populations of minor bodies in the outer Solar System remain particularly elusive: Scattered Disk objects and Sedna-like objects. These populations are important dynamical tracers, and understanding the details of their spatial- and size ...

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 ...

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.

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.

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.

Pencil-Beam Surveys for Faint Trans-Neptunian Objects [PDF]

, 1998
We have conducted pencil-beam searches for outer solar system objects to a limiting magnitude of R ~ 26. Five new trans-neptunian objects were detected in these searches.

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.

Evidence for Color Dichotomy in the Primordial Neptunian Trojan Population [PDF]

, 2018
In the current model of early Solar System evolution, the stable members of the Jovian and Neptunian Trojan populations were captured into resonance from the leftover reservoir of planetesimals during the outward migration of the giant planets.

Trans-Neptunian Objects with Hubble Space Telescope ACS/WFC [PDF]

, 2010
We introduce a novel search technique that can identify trans-neptunian objects in three to five exposures of a pointing within a single Hubble Space Telescope orbit. The process is fast enough to allow the discovery of candidates soon after the data are
