Context. Recent results suggest that there is a group of trans-Neptunian objects (TNOs) (2003 EL 61 being the biggest member), with surfaces composed of almost pure water ice and with very similar orbital elements. These objects provide exciting laboratories for the study of the processes that prevent the formation of an evolved mantle of organics on the surfaces of the bodies in the trans-Neptunian belt (TNb). Aims. We study the surface composition of another TNO that moves in a similar orbit…

Context. Previously known as 2003 EL61, (136108) Haumea, is the largest member of a group of trans-Neptunian objects (TNOs) with similar orbits and “unique” spectral characteristics in the form of a
Visible spectroscopy in the neighborhood of 2003EL61
Context. The recent discovery of a group of trans-neptunian objects (TNOs) in a narrow region of the orbital parameter space and with surfaces composed of almost pure water ice, being 2003 EL 61 its
Experimenting with Mixtures of Water Ice and Dust as Analogues for Icy Planetary Material
Due to its abundance and unique properties, water is a major actor in the formation and evolution of many planetary surfaces as well as a sensitive and reliable tracer of past geologic and climatic
Methane, ammonia, and their irradiation products at the surface of an intermediate-size KBO? A portrait of Plutino (90482) Orcus
Orcus is an intermediate-size 1000 km-scale Kuiper belt object (KBO) in 3:2 mean-motion resonance with Neptune, in an orbit very similar to that of Pluto. It has a water-ice dominated surface with
The dynamical evolution of dwarf planet (136108) Haumea’s collisional family: general properties and implications for the trans-Neptunian belt
Recently, the first collisional family was identified in the trans-Neptunian belt (otherwise known as the Edgeworth-Kuiper belt), providing direct evidence of the importance of collisions between
Characterisation of candidate members of (136108) Haumea's family II. Follow-up observations
Context. From a dynamical analysis of the orbital elements of trans-Neptunian objects (TNOs), Ragozzine & Brown (2007, AJ, 134, 2160) reported a list of candidate members of the first collisional
New insights on ices in Centaur and Transneptunian populations


Trans-neptunian object (55636) 2002 TX$\mathsf{_{300}}$, a fresh icy surface in the outer solar system
Context. The knowledge of the physical properties of the population of known large trans-Neptunian objects (TNOs) is a key issue in understanding the origin and evolution of the Solar System. In
We report the detection of crystalline water ice on the surface of 2003 EL_(61). Reflectance spectra were collected from the Gemini North telescope in the 1.0 to 2.4 μm wavelength range and from the
Water ice on the surface of the large TNO 2004 DW
We have obtained visible and near infrared spectra of the Trans Neptunian object 2004 DW, a few days after its discovery, at the Telescopio Nazionale Galileo (TNG). 2004 DW belongs to the plutino
Crystalline water ice on the Kuiper belt object (50000) Quaoar
It is concluded that Quaoar has been recently resurfaced, either by impact exposure of previously buried (shielded) ices or by cryovolcanic outgassing, or by a combination of these processes.
ESO Large Program on physical studies of Trans-Neptunian objects and Centaurs: Final results of the visible spectrophotometric observations
The Large Program on physical studies of TNOs and Centaurs, started at ESO Cerro Paranal on April 2001, has recently been concluded. This project was devoted to the investigation of the surface
Water frost on Charon
The current series of mutual eclipses between Pluto and its satellite, Charon, provides a very powerful means of probing the most distant known planet in our Solar System. Observations from 1985 and
The Surface Composition of Charon: Tentative Identification of Water Ice
The 3 March 1987 Charon occultation by Pluto was observed in the infrared at 1.7, 2.0, and 2.35 micrometers, and measurements suggest the existence of water ice on Pluto's moon.

We report complete near-infrared (0.9-2.4 μ m) spectral observations of trans-neptunian objects (TNOs) 2000 EB173 and 2000 WR106 collected using the new Near Infrared Camera Spectrometer (NICS)
Evidence for crystalline water and ammonia ices on Pluto's satellite charon.
Observations have resolved the satellite Charon from its parent planet Pluto, giving separate spectra of the two objects from 1.0 to 2.5 micrometers. The spectrum of Charon is found to be different
