Context. The population of known large trans-neptunian objects (TNOs) is growing very fast and the knowledge of their physical properties is a key issue to understand the origin and evolution of the Solar System. Aims. In this paper we studied the surface composition of the recently discovered TNO 2005 FY 9 , one of the largest known TNOs (~0.7 times the diameter of Pluto, i.e. 1600 km, if the albedo is similar, or 3100–1550 km in diameter assuming an albedo range 0.2  p V Methods. We report…

Visible spectroscopy of 2003 UB313: Evidence for N2 ice on the surface of the largest TNO?
The recent discovery of two large trans-Neptunian objects (TNOs) 2003 UB313 and 2005 FY9, with surface properties similar to those of Pluto, provides an exciting new laboratory for the study of
TNO surface ices - Observations of the TNO 55638 (2002 VE$_\mathsf{95}$) and analysis of the population's spectral properties
Aims. We investigate the surface composition of Centaurs and Trans-Neptunian objects (TNOs) to get constraints on the formation and the evolution of this population. Methods. We report visible and
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
The spectrum of Pluto, 0.40–0.93 μm - I. Secular and longitudinal distribution of ices and complex organics
Context. During the past 30 years the surface of Pluto has been characterized and its variability monitored through continuous nearinfrared spectroscopic observations. But in the visible range only a
The very homogeneous surface of the dwarf planet Makemake
The dwarf planet (136472) Makemake is one of the largest trans-Neptunian objects discovered to date. Noteworthy, the size and surface temperature of this celestial body put it in a transition region
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
Comparative Kbology: Using Surface Spectra of Triton, Pluto, and Charon to Investigate Atmospheric, Surface, and Interior Processes on Kuiper Belt Objects
We present the results of an investigation to determine the longitudinal (zonal) distributions and temporal evolution of ices on the surface of Triton. Between 2002 and 2014, we obtained 63 nights of
Short-term rotational variability in the large TNO 2005FY9
Context. Despite the fact that 2005FY 9 is one of the largest trans-Neptunian objects (TNOs) and a dwarf planet candidate, little is known about this object apart from constraints on its surface

Crystalline water ice on the Kuiper belt object (50000) Quaoar
TLDR
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.
