Stellar Occultations by Trans-Neptunian Object Satellites: Predictions and Observations

The Planetary Science Journal
With the great success of stellar occultations in probing trans-Neptunian objects (TNOs), these observations have become ubiquitous, leading to significant advances in our knowledge of TNOs. As stellar occultation predictions have improved, it has become

TRITON'S EVOLUTION WITH A PRIMORDIAL NEPTUNIAN SATELLITE SYSTEM. [PDF]

Astronomical Journal, 2017
Abstract The Neptunian satellite system is unusual. The major satellites of Jupiter, Saturn, and Uranus are all in prograde, low-inclination orbits. Neptune on the other hand, has the fewest satellites, and most of the system’s mass is within one irregular satellite, Triton.

Astrometric observations of Uranian and Neptunian satellites with the Pulkovo and Crimean observatory telescopes in 2020 [PDF]

Астрономия и исследование космического пространства: Всероссийская с международным участием научная конференция студентов и молодых ученых, посвященная памяти Полины Евгеньевны Захаровой, 2021
The paper presents the results of observations of the Uranian and Neptunian satellites performed in 2020 with the 1-meter mirror telescope ‘Saturn’ (Pulkovo observatory) and the 350-mm guide telescope of the ‘Sintez’ telescope (Crimean observatory). More than 8 thousand separate positions of the satellites were obtained in the Gaia EDR3 catalog system.

Accurate geometric albedo, shape, and size of Hi’iaka from a stellar occultation [PDF]

Nature Communications
Stellar occultations, when a distant object passes in front of a star and casts a shadow on Earth, are a powerful tool to probe the physical properties of solar system bodies.

Weywot, an Unusually Low-albedo Satellite in the Trans-Neptunian Region

The Astrophysical Journal Letters
Weywot is the largest satellite of the candidate dwarf planet Quaoar, which also hosts a remarkable ring system located beyond its Roche limit—a configuration that challenges conventional understanding of ring dynamics.

Probing close-in satellites of trans-Neptunian objects through thermal and direct size measurements

Astronomy & Astrophysics
Context. Trans-Neptunian objects are distant bodies that retain valuable information about the origin and evolution of the Solar System. Many of these objects constitute binary systems.

THE ORBITS OF THE NEPTUNIAN SATELLITES AND THE ORIENTATION OF THE POLE OF NEPTUNE

Astronomical Journal, 2009
This paper reports on an update to the orientation of Neptune's pole and to the orbits of the Neptunian satellites, Triton, Nereid, and Proteus. We determined the new pole and orbits in the International Celestial Reference Frame by fitting them to all available observations through the opposition of 2008.

Discovery of a Satellite of the Large Trans-Neptunian Object (225088) 2007 OR₁₀ [PDF]

The Astrophysical Journal Letters, 2017
Abstract 2007 OR10 is currently the third largest known dwarf planet in the trans-Neptunian region, with an effective radiometric diameter of ∼1535 km. It has a slow rotation period of ∼45 hr that was suspected to be caused by tidal interactions with a satellite undetected at that time.
