On the surface composition of Triton’s southern latitudes

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 surface compositions of Pluto and Charon

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

The subsurface of Pluto from submillimetre observations

Surface areas on Pluto change in brightness and colour, at optical to infrared wavelengths, over time-scales as short as years. The subsurface contains a reservoir of frozen volatiles, but little is

New constraints on the surface of Pluto

Aims. Spectroscopic investigation of the surface of Pluto allows us to constrain the chemical properties of the volatile species of the solar system reservoir. This permits us to obtain the relative

Spectral mapping and long-term seasonal evolution of Pluto

NASA's New Horizons mission has provided a wealth of new data about the Pluto system, including detailed surface geology and volatile distribution maps revealing striking latitudinal and longitudinal



Distribution and Evolution of CH4, N2, and CO Ices on Pluto's Surface: 1995 to 1998

Abstract We present new near-infrared spectra of the planet Pluto obtained at Lowell Observatory on 83 nights during 1995–1998. The dense temporal sampling of our observations enables us to measure

Spatial and Compositional Constraints on Non-ice Components and H2O on Pluto's Surface

We present four new near-infrared spectra of Pluto, measured separately from its satellite Charon during four HST/NICMOS observations in 1998, timed to sample four evenly spaced longitudes on Pluto.

Synoptic CCD Spectrophotometry of Pluto Over the Past 15 Years

Over the 15 years from 1980 to 1994, the same spectrometer has been used to obtain spectrophotometric observations of Pluto+Charon over the wavelength range from 0.5 to 1.0 μm. This time period

Pluto's Non-isothermal Surface

We report on repeated far-infrared photometric observations of the Pluto–Charon system conducted in 1997 with the Infrared Space Observatory (ISO). These observations have led to the first detection

CVF spectrophotometry of Pluto: Correlation of composition with Albedo


We present new photometric and spectroscopic data of the dwarf planet Eris obtained on 2006 October and 2007 December with the Very Large Telescopes at ESO, Chile. We use three different instruments

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


Introduction: We present near-infrared spectra 0.8 – 2.5 μm of Pluto (Fig. 1) and its satellite Charon (Fig. 2) obtained with the CorMASS [1] spectrometer while it was a visiting instrument at the
