No Evidence for Orbital Clustering in the Extreme Trans-Neptunian Objects [PDF]
The Planetary Science Journal, 2021 The apparent clustering in longitude of perihelion ϖ and ascending node Ω of extreme trans-Neptunian objects (ETNOs) has been attributed to the gravitational effects of an unseen 5–10 Earth-mass planet in the outer solar system.

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.

Orbital Dynamics Landscape near the Most Distant Known Trans-Neptunian Objects [PDF]
Astrophysical Journal, 2022 The most distant known trans-Neptunian objects (TNOs), those with perihelion distance above 38 au and semimajor axis above 150 au, are of interest for their potential to reveal past, external, or present but unseen perturbers.

The Von Zeipel–Lidov–Kozai Effect inside Mean Motion Resonances with Applications to Trans-Neptunian Objects [PDF]
Astronomical Journal, 2022 Secular dynamics inside mean motion resonances (MMRs) plays an essential role in governing the dynamical structure of the trans-Neptunian region and sculpting the orbital distribution of trans-Neptunian objects (TNOs).

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).

The Rarity of Very Red Trans-Neptunian Objects in the Scattered Disk [PDF]
, 2021 We investigate the origins of the photometrically very red (VR) and less red (LR) trans-Neptunian objects (TNOs). We first reanalyze the data set of Marsset et al.

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

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 ...

Long-term orbital dynamics of trans-Neptunian objects [PDF]
Celestial mechanics & dynamical astronomy, 2020 This article reviews the different mechanisms affecting the orbits of trans-Neptunian objects, ranging from internal perturbations (planetary scattering, mean-motion resonances, and secular effects) to external perturbations (galactic tides and passing ...
