Stellar occultations provide a powerful tool to explore objects of the outer solar system. The
Gaia mission now provides milli-arcsec accuracy on the predictions of these events and …

Abstract The dwarf planets Sedna, Gonggong, and Quaoar are interesting in being
somewhat smaller than the methane-rich bodies of the Kuiper Belt (Pluto, Eris, Makemake) …

We were able to accurately predict the shadow path and successfully observe an occultation
of a bright star by Chiron on December 15, 2022. The Kottamia Astronomical Observatory in …

The study of the polarisation of light is a powerful tool for probing the physical and
compositional properties of astrophysical sources, including Solar System objects. In this …

The dwarf planet Haumea is one of the most compelling trans-Neptunian objects to study,
hosting two small, dynamically interacting satellites, a family of nearby spectrally unique …

We report on the discovery of a very prominent mid-infrared (18–25 μm) excess associated
with the trans-Neptunian dwarf planet (136472) Makemake. The excess, detected by the Mid …

A stellar occultation of Gaia DR3 2646598228351156352 by the Centaur (2060) Chiron was
observed from the South African Astronomical Observatory on 2018 November 28 UT. Here …

ABSTRACT The Centaur (60558) Echeclus was discovered on 2000 March 03, orbiting
between the orbits of Jupiter and Uranus. After exhibiting frequent outbursts, it also received …

Abstract Kuiper Belt objects (KBOs) show an unexpected trend, whereby large bodies have
increasingly higher densities, up to five times greater than their smaller counterparts. Current …

Recent stellar occultations have allowed accurate instantaneous size and apparent shape
determinations of the large Kuiper belt object (50000) Quaoar and the detection of two rings …
