Time series photometry of the dwarf planet ERIS (2003 UB313)
Context. The dwarf planet Eris (2003 UB313, formerly known also as "Xena") is the largest KBO discovered up to now. Despite being larger than Pluto and having many similarities to it, it has not been
A study of photometric variations on the dwarf planet (136199) Eris
Context. Eris is the largest dwarf planet currently known in the solar system. Knowledge about its physical parameters is necessary to interpret the characteristics of these kinds of bodies. Aims.
The Mass of Dwarf Planet Eris
New observations with the Keck Observatory and the Hubble Space Telescopes show that Dysnomia has a circular orbit with a radius of 37,350 � 140 (1-σ) kilometers and a 15.774 � 0.002 day orbital period around Eris, which agrees with expectations for a satellite formed out of the orbiting debris left from a giant impact.
Tentative detection of the rotation of Eris
We describe the discovery of a satellite in orbit about the dwarf planet (136472) Makemake. This satellite, provisionally designated S/2015 (136472) 1, was detected in imaging data collected with the
The origin of Pluto's peculiar orbit
THE origin of Pluto's unusual orbit—the most eccentric and inclined of all the planets—remains a mystery. The orbits of Pluto and Neptune overlap, but close approaches of these two planets are
A Pluto-like radius and a high albedo for the dwarf planet Eris from an occultation
The observation of a multi-chord stellar occultation by Eris on 6 November 2010 is reported, consistent with a spherical shape for Eris, and it is anticipated that this atmosphere may periodically sublimate as Eris approaches its perihelion, at 37.8 astronomical units from the Sun.
Formation of Iapetus’ Extreme Albedo Dichotomy by Exogenically Triggered Thermal Ice Migration
It is demonstrated that all these characteristics, and the asymmetry’s large amplitude, can be plausibly explained by runaway global thermal migration of water ice, triggered by the deposition of dark material on the leading hemisphere.
