Context. The paths followed by the known extreme trans-Neptunian objects (ETNOs) effectively avoid direct gravitational perturbations from the four giant planets, yet their orbital eccentricities are in the range between 0.69–0.97. Solar system dynamics studies show that such high values of the eccentricity can be produced via close encounters or secular perturbations. In both cases, the presence of yet-to-be-discovered trans-Plutonian planets is required. Recent observational evidence cannot… Expand

Peculiar orbits and asymmetries in extreme trans-Neptunian space
It is still an open question how the Solar system is structured beyond 100 au from the Sun. Our understanding of this vast region remains very limited and only recently we have become aware of theExpand

Binary stripping as a plausible origin of correlated pairs of extreme trans-Neptunian objects
Asteroids that follow similar orbits may have a dynamical connection as their current paths could be the result of a past interaction with a massive perturber. The pair of extreme trans-NeptunianExpand
Extreme trans-Neptunian objects and the Kozai mechanism: signalling the presence of trans-Plutonian planets.
The existence of an outer planet beyond Pluto has been a matter of debate for decades and the recent discovery of 2012 VP113 has just revived the interest for this controversial topic. ThisExpand
Non-resonant secular dynamics of trans-Neptunian objects perturbed by a distant super-Earth
We use a secular model to describe the non-resonant dynamics of trans-Neptunian objects in the presence of an external ten-Earth-mass perturber. The secular dynamics is analogous to an “eccentricExpand
EVIDENCE FOR A DISTANT GIANT PLANET IN THE SOLAR SYSTEM
Recent analyses have shown that distant orbits within the scattered disk population of the Kuiper Belt exhibit an unexpected clustering in their respective arguments of perihelion. While severalExpand

Over the course of the past two decades, observational surveys have unveiled the intricate orbital structure of the Kuiper Belt, a field of icy bodies orbiting the Sun beyond Neptune. In addition toExpand
Evidence for a possible bimodal distribution of the nodal distances of the extreme trans-Neptunian objects: Avoiding a trans-Plutonian planet or just plain bias?
It is a well-known fact that the presence of a massive perturber interacting with a population of minor bodies following very eccentric orbits can strongly affect the distribution of their nodalExpand

A Sedna-like body with a perihelion of 80 astronomical units
TLDR
The detection of 2012 VP113 confirms that Sedna is not an isolated object; instead, both bodies may be members of the inner Oort cloud, whose objects could outnumber all other dynamically stable populations in the Solar System. Expand
OSSOS XV: PROBING THE DISTANT SOLAR SYSTEM WITH OBSERVED SCATTERING TNOS.
TLDR
It is confirmed that observed scattering objects cannot solely originate from the classical Kuiper belt, and it is shown that both the Oort cloud and a distant planet generate observable highly inclined scatterers. Expand
