The rotational states of the members in the dwarf planet - satellite systems in the transneptunian region are determined by the formation conditions and the tidal interaction between the components, and these rotational characteristics are the prime tracers of their evolution. Previously a number of authors claimed highly diverse values for the rotation period for the dwarf planet Eris, ranging from a few hours to a rotation (nearly) synchronous with the orbital period (15.8 d) of its satellite…

Masses and Densities of Dwarf Planet Satellites Measured with ALMA

We have used the Atacama Large Millimeter/submillimeter Array to measure precise absolute astrometric positions and detect the astrometric wobble of dwarf planet Orcus and its satellite Vanth over a…

Rotational Phase Dependent J − H Colour of the Dwarf Planet Eris

The largest bodies—or dwarf planets—constitute a different class among Kuiper Belt objects and are characterized by bright surfaces and volatile compositions remarkably different from that of smaller…

The Impact of Serpentinization on the Initial Conditions of Satellite Forming Collisions of Large Kuiper Belt Objects

Kuiper Belt objects are thought to be formed at least a few million years after the formation of calcium–aluminum-rich inclusions (CAIs), at a time when the 26Al isotope—the major source of…

The internal structure of Eris inferred from its spin and orbit evolution

The large Kuiper Belt object Eris is tidally locked to its small companion Dysnomia. Recently obtained bounds on the mass of Dysnomia demonstrate that Eris must be unexpectedly dissipative for it to…

Low Rock Mass Fraction Within Trans‐Neptunian Objects Inferred From the Spin–Orbit Evolution of Orcus–Vanth and Salacia–Actaea

Satellites play a crucial role in understanding the formation and evolution of trans‐Neptunian objects (TNOs). The spin–orbit evolution of satellite systems depends on their thermal histories,…

Analysis of the ATLAS photometry of the dwarf planets (134340) Pluto and (136199) Eris

This manuscript analyzes forced photometry data of the dwarf planets Pluto and Eris obtained by the ATLAS network between 2015 and 2023 using the o- and c-band filters. The phase curves of Pluto and…

Trans-Neptunian objects: More than meets the ice

Eris, the second largest trans-Neptunian object (136199), melted early and maintains a warm ice conductive ice shell unlike Pluto.

Till quite recently, only one vase was known with a picture of Icarus. The publication of the black-figure fragments from the Acropolis added a second. I am putting a third to these, possibly a…
