The dwarf planet Eris is a trans-Neptunian object with an orbital eccentricity of 0.44, an inclination of 44 degrees and a surface composition very similar to that of Pluto. It resides at present at 95.7 astronomical units (1 au is the Earth-Sun distance) from Earth, near its aphelion and more than three times farther than Pluto. Owing to this great distance, measuring its size or detecting a putative atmosphere is difficult. Here we report the observation of a multi-chord stellar occultation… Expand
Albedo and atmospheric constraints of dwarf planet Makemake from a stellar occultation
TLDR
The disappearances and reappearances of the star were abrupt, showing that Makemake has no global Pluto-like atmosphere at an upper limit of 4–12 nanobar (1σ) for the surface pressure, although a localized atmosphere is possible. Expand
Planetary science: Eris under scrutiny
A stellar occultation by the dwarf planet Eris provides a new estimate of its size. It also reveals a surprisingly bright planetary surface, which could indicate the relatively recent condensation ofExpand
Results from a triple chord stellar occultation and far-infrared photometry of the trans-Neptunian object (229762) 2007 UK126
Context. A stellar occultation by a trans-Neptunian object (TNO) provides an opportunity to probe the size and shape of these distant solar system bodies. In the past seven years, severalExpand
The size, shape, density and ring of the dwarf planet Haumea from a stellar occultation
TLDR
Observations from multiple Earth-based observatories of Haumea passing in front of a distant star (a multi-chord stellar occultation) report the presence of a ring with an opacity of 0.5, which constrains the three-dimensional orientation of Haumesa and its triaxial shape, which is inconsistent with a homogeneous body in hydrostatic equilibrium.

A terrestrial planet candidate in a temperate orbit around Proxima Centauri
TLDR
Observations reveal the presence of a small planet with a minimum mass of about 1.3 Earth masses orbiting Proxima with a period of approximately 11.2 days at a semi-major-axis distance of around 0.05 astronomical units. Expand
Discovery and physical characterization of a large scattered disk object at 92 au

Results of two multichord stellar occultations by dwarf planet (1) Ceres
We report the results of two multi-chord stellar occultations by the dwarf planet (1) Ceres that were observed from Brazil on 2010 August 17, and from the USA on 2013 October 25. Four positiveExpand
Stellar occultations by Trans-Neptunian objects: From predictions to observations and prospects for the future
TLDR
Most of the aspects involved in the complex process to successfully observe occultations are reviewed, and some of the lessons learned may allow an increase in the success rate and scientific output of the occultation technique applied to TNOs, in the short-term future. Expand
Occultation of a Large Star by the Large Plutino (28978) Ixion on 2020 October 13 UTC
We observed the occultation of the star Gaia DR2 4056440205544338944 by (28978) Ixion. The event was observed from two Lowell Observatory sites, using the 4.3 m Lowell Discovery Telescope (LDT), nearExpand

The trans-neptunian object UB313 is larger than Pluto
TLDR
Observations of the thermal emission of 2003 UB313 at a wavelength of 1.2 mm are reported, which in combination with the measured optical brightness leads to a diameter of 3,000 ± 300 ± 100 km, which makes 2003 Ub313 the largest known trans-neptunian object, even larger than Pluto. Expand

Size and albedo of Kuiper belt object 55636 from a stellar occultation
TLDR
Observations of a multi-chord stellar occultation by KBO 55636, which occurred on 9 October 2009, find that it has a mean radius of 143 ± 5 km and a geometric albedo of in the V photometric band, which establishes that KBO55636 is smaller than previously thought and that, like its parent body, it is highly reflective.
