Haumea—one of the four known trans-Neptunian dwarf planets—is a very elongated and
rapidly rotating body,,. In contrast to other dwarf planets,,, its size, shape, albedo and density …

Hitherto, rings have been found exclusively around the four giant planets in the Solar
System. Rings are natural laboratories in which to study dynamical processes analogous to …

Here we measure the absolute magnitude distributions (H-distribution) of the dynamically
excited and quiescent (hot and cold) Kuiper Belt objects (KBOs), and test if they share the …

HiPERCAM is a portable, quintuple-beam optical imager that saw first light on the 10.4-m
Gran Telescopio Canarias (GTC) in 2018. The instrument uses re-imaging optics and four …

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 …

Amateur contributions to professional publications have increased exponentially over the
last decades in the field of planetary astronomy. Here we review the different domains of the …

Abstract The Minerva-Australis telescope array is a facility dedicated to the follow-up,
confirmation, characterization, and mass measurement of planets orbiting bright stars …

Abstract James Webb Space Telescope's NIRSpec infrared imaging spectrometer observed
the outer solar system dwarf planets Eris and Makemake in reflected sunlight at wavelengths …

We propose that several short-duration events observed in past stellar occultations by
Chiron were produced by ring material. Some similarities between these events and the …

Aims. The goal of this work is to characterize the ensemble thermal properties of the
Centaurs/trans-Neptunian population. Methods. Thermal flux measurements obtained with …
