Large size and slow rotation of the trans-Neptunian object (225088) 2007 OR10 discovered from Herschel and K2 observations [PDF]

, 2016
We present the first comprehensive thermal and rotational analysis of the second most distant trans-Neptunian object (225088) 2007 OR10. We combined optical light curves provided by the Kepler space telescope -- K2 extended mission and thermal infrared ...

Generation of Highly Inclined Trans-Neptunian Objects by Planet Nine [PDF]

, 2016
The trans-Neptunian region of the solar system exhibits an intricate dynamical structure, much of which can be explained by an instability-driven orbital history of the giant planets.

Origin and Dynamical Evolution of Neptune Trojans - I: Formation and Planetary Migration [PDF]

, 2009
We present the results of detailed dynamical simulations of the effect of the migration of the four giant planets on both the transport of pre-formed Neptune Trojans, and the capture of new Trojans from a trans-Neptunian disk.

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).

Light Curves of Trans-Neptunian Objects from the K2 Mission of the Kepler Space Telescope

The Astrophysical Journal Supplement Series, 2023
The K2 mission of the Kepler Space Telescope allowed the observations of light curves of small solar system bodies throughout the whole solar system. In this paper, we present the results of a collection of K2 trans-Neptunian object observations between ...

The scattered trans-Neptunian object 1998 XY95 [PDF]

Monthly Notices of the Royal Astronomical Society, 2001
On 1998 December 12 a new trans-Neptunian object, 1998 XY95, was discovered as part of a deep search. Recent observations of this object have placed it amongst the class of objects known as the scattered trans-Neptunian objects (TNOs). A total of 39 CCD images of 1998 XY95 were taken over two nights, and these were used to search for a light curve, but

Pairs of Trans-Neptunian Objects with close orbits [PDF]

Астрономия и исследование космического пространства: Всероссийская с международным участием научная конференция студентов и молодых ученых, посвященная памяти Полины Евгеньевны Захаровой, 2021
A search for pairs of dynamically correlated trans-Neptunian objects with semi-major axes of more than 30 au was performed. The Kholshevnikov metrics in the space of Keplerian orbits are used. Found 27 pairs with metrics less than 0.07 au1/2, 22 pairs in which one of the components is binary, for metrics less than 0.12 au1/2, and 11 pairs of binary ...

Steeper Scattered Disks Buckle Faster

The Astrophysical Journal Letters, 2023
Disks of low-mass bodies scattered by giant planets to large semimajor axis and constant periapsis orbits are vulnerable to a buckling instability. This instability exponentially grows orbital inclinations, raises periapsis distances, and coherently ...

Neptune Trojans and Plutinos: colors, sizes, dynamics, and their possible collisions [PDF]

, 2009
Neptune Trojans and Plutinos are two subpopulations of trans-Neptunian objects located in the 1:1 and the 3:2 mean motion resonances with Neptune, respectively, and therefore protected from close encounters with the planet.
