The origin of (47171) Lempo-like Kuiper belt triple systems during binary-binary interactions
(Oxford University Press, 2020-12)
The trans-Neptunian triple Lempo-Paha-Hiisi is composed of a tight inner binary with components of similar size and an outer companion about half their size orbiting 10 times further away. Large trans-Neptunian objects ...
Binary-binary close encounters in the Kuiper Belt
(Wiley Blackwell Publishing, Inc, 2021-07)
Trans-Neptunian binaries are among the objects carrying the most relevant information on the conditions that prevailed in the primitive outer Solar system. However, their present orbital architecture not necessarily reflects ...
An interstellar origin for high-inclination Centaurs
(Oxford Univ Press, 2020-05-01)
We investigate the possible origins of real high-inclination Centaurs and trans-neptunian objects using a high-resolution statistical search for stable orbits that simulates their evolution back in time to the epoch when ...
First trans-neptunian object in polar resonance with neptune
(2017-11-21)
Capture in mean motion resonance has been observed in the Solar system for small objects with prograde as well as retrograde orbits of moderate inclinations. However, no example of an object with a nearly polar orbit was ...
The disturbing function for polar Centaurs and transneptunian objects
(2017-01-01)
The classical disturbing function of the three-body problem is based on an expansion of the gravitational interaction in the vicinity of nearly coplanar orbits. Consequently, it is not suitable for the identification and ...
A mid-term astrometric and photometric study of trans-Neptunian object (90482) Orcus
(Edp Sciences, 2010-11)
From time series CCD observations of a fixed and large star field that contained the binary trans-Neptunian object (90482) Orcus (formerly 2004 DW), taken during a period of 33 days, we have been able to derive high-precision ...
