Context. The trans-Neptunian region of the Solar System is populated by a wide variety of icy bodies showing great diversity in orbital behavior, size, surface color, and composition. One can also see there are dynamical families and binary systems. One surprising feature detected in the spectra of some of the largest trans-Neptunians is the presence of crystalline water-ice. This is the case for the large TNO (136 108) Haumea (2003 EL61 ).Aims. We seek to constrain the state of the water ice…

Near-infrared spatially resolved spectroscopy of (136108) Haumea's multiple system
The transneptunian region of the solar system is populated by a wide variety of icy bodies showing great diversity. The dwarf planet (136108) Haumea is among the largest TNOs and displays a highly
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
Methanol ice on the surface of minor bodies in the solar system
Aims. Spectral analyses of trans-Neptunan objects (TNOs) and of the linked Centaurs, which are supposed to be among the most primitive minor bodies in the solar system, reveal some chemical and
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
Photometric Measurements of H2O Ice Crystallinity on Trans-Neptunian Objects
We present a measurement of H2O ice crystallinity on the surface of trans-neptunian objects (TNOs) with near-infrared narrow-band imaging. The newly developed photometric technique allows us to
Integral-field spectroscopy of (90482) Orcus-Vanth
Aims. We seek to constrain the surface composition of the trans-Neptunian object (90482) Orcus and its small satellite Vanth, as well as their mass and density. Methods. We acquired near-infrared
Spectral variability of Charon’s 2.21-μm feature
Abstract The clear angular separation of Pluto and Charon from ground-based telescopes has been enabled by improved technology, particularly adaptive optics systems. Near-infrared spectral data have
An Icy Kuiper-Belt Around the Young Solar-Type Star HD 181327
Context. HD 181327 is a young main sequence F5/F6 V star belonging to the beta Pictoris moving group (age similar to 12 Myr). It harbors an optically thin belt of circumstellar material at radius
The Compositions of Kuiper Belt Objects
Objects in the Kuiper belt are difficult to study in detail, even with the best telescopes available. Therefore, for many years, studies of the compositions of these objects were relegated to
“TNOs are Cool”: a survey of the trans-Neptunian region - VII. Size and surface characteristics of (90377) Sedna and 2010 EK139
We present estimates of the basic physical properties (size and albedo) of (90377) Sedna, a prominent member of the detached trans-Neptunian object population and the recently discovered scattered

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
Properties of the icy surface of the TNO 136108 (2003 EL$_{\sf 61}$)
Context. Spectroscopic observations of numerous trans-Neptunian objects (TNOs), considered to be among the most pristine objects of the solar system, have revealed the presence of several kinds of
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.
Surface composition of the largest dwarf planet 136199 Eris (2003 UB313)
Aims. The surface composition of the largest TNO, the dwarf planet 136199 Eris, is studied and compared to Pluto’s. Methods. High signal-to-noise visible and near-infrared reflectance spectra were
