The most distant known object in the Solar System, 2003 UB313 (97 au from the Sun), was recently discovered near its aphelion. Its high eccentricity and inclination to the ecliptic plane, along with its perihelion near the orbit of Neptune, identify it as a member of the ‘scattered disk’. This disk of bodies probably originates in the Kuiper belt objects, which orbit near the ecliptic plane in circular orbits between 30 and 50 au, and may include Pluto as a member. The optical brightness of… Expand
Solar system: A planet more, a planet less?
Further observations of an object dubbed 2003 UB313, which lies beyond Neptune, show that its diameter is around 3,100 kilometres. This makes it larger than Pluto, the smallest ‘traditional’ SolarExpand
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. Expand
Occultation of X-rays from Scorpius X-1 by small trans-neptunian objects
The discovery of such occultation events at millisecond timescales in the X-ray light curve of Scorpius X-1 is reported, in line with an extrapolation of the distribution of sizes of larger TNOs. Expand
Trans-Neptunian Objects as Natural Probes to the Unknown Solar System
Trans-Neptunian objects (TNOs) are icy/rocky bodies that move beyond the orbit of Neptune in a region known as the trans-Neptunian belt (or Edgeworth-Kuiper belt). In contrast to the predictions ofExpand
Trans-Neptunian objects and Centaurs at thermal wavelengths
Abstract The thermal emission of Trans-Neptunian objects and Centaurs has been observed at mid- and far-infrared wavelengths—with the biggest contributions coming from the Spitzer and Herschel spaceExpand
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
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.Expand
Possible patterns in the distribution of planetary formation regions
Eris, an object larger than Pluto, is known to reside in the transneptunian region further away than Pluto. One can wonder whether its semimajor orbital axis ts in a generalized Titius-Bode law, inExpand
Polarimetry of the dwarf planet (136199) Eris
Context. We study the surface properties of the transneptunian population of Solar-system bodies. Aims. We investigate the surface characteristics of the large dwarf planet (136199) Eris. Methods.Expand
The thermal emission of Centaurs and Trans-Neptunian objects at millimeter wavelengths from ALMA observations
The sensitivity of ALMA makes it possible to detect thermal mm/submm emission from small/distant Solar System bodies at the sub-mJy level. Measured fluxes are primarily sensitive to the objects'Expand


Discovery of a Planetary-sized Object in the Scattered Kuiper Belt
We present the discovery and initial physical and dynamical characterization of the object 2003 UB313. The object is sufficiently bright that for all reasonable values of the albedo it is certain toExpand
Photometric Observations Constraining the Size, Shape, and Albedo of 2003 EL61, a Rapidly Rotating, Pluto-sized Object in the Kuiper Belt
We present measurements at optical wavelengths of the spectral reflectance, rotational light curve, and solar phase curve of 2003 EL61. With apparent visual magnitude 17.5 at 51 AU from the Sun, thisExpand
Time-resolved photometry of kuiper belt objects: rotations, shapes and phase functions
We present a systematic investigation of the rotational light curves of trans-Neptunian objects based on extensive optical data from Mauna Kea. Four of 13 objects (corresponding to 31%) in our sampleExpand
Albedo Maps of Pluto and Improved Physical Parameters of the Pluto-Charon System
Abstract We present an analysis of photometric observations of the Pluto-Charon rotational and mutual event light curves obtained between 1982 and 1990. The dataset covers 18 satellite transitsExpand
Pluto's Lightcurve: Results from Four Oppositions
Abstract The rotational lightcurve, phase function, and orbital lightcurve of the Pluto-Charon system were measured in blue light over four consecutive oppositions spanning 1980 to 1983. ComparedExpand
Comparative mapping of Pluto's sub-Charon hemisphere - Three least squares models based on mutual event lightcurves
Photometric observations of Pluto-Charon transit events obtained at the University of Texas McDonald Observatory from 1985 through 1990 enable us to construct a normal reflectance map for theExpand
Size estimates of some optically bright KBOs
Seven recently detected optically "bright" Kuiper-Belt-Objects (KBOs) were observed at 250 GHz using the Max-Planck Millimeter Bolometer (MAMBO) array at the IRAM 30 m telescope. Only the opticalExpand
