Asteroid 1 Ceres: evidence for water of hydration.
TLDR
An absorption feature centred near 3.0 microns has been discovered in the infrared spectrum of asteroid 1 Ceres as mentioned in this paper, which suggests the presence of about 10-15 per cent water in the form of water of hydration on the surface of Ceres.Abstract:
An absorption feature centred near 3.0 microns has been discovered in the infrared spectrum of asteroid 1 Ceres. This spectrum has been compared with laboratory spectra of meteorites and shows great similarity to the spectra of type II carbonaceous chondrites. By analogy this suggests the presence of about 10-15 per cent water in the form of water of hydration on the surface of Ceres. This is the first evidence of water in the surface material of an asteroid.read more

Phase II of the Small Main-Belt Asteroid Spectroscopic Survey: A Feature-Based Taxonomy
Schelte J. Bus,Richard P. Binzel +1 more
TL;DR: The second phase of the Small Main Belt Asteroid Spectroscopic Survey (SMASSII) produced an internally consistent set of visible-wavelength charge-coupled device (CCD) spectra for 1447 asteroids.

Density of asteroids
TL;DR: DeMeo et al. as mentioned in this paper presented a review of the current knowledge of the density of small bodies and compared with meteorite density, allowing to estimate the macroporosity (i.e., amount of voids) within these bodies.

The composition and origin of the C, P, and D asteroids: Water as a tracer of thermal evolution in the outer belt
TL;DR: In this article, a telescopic and laboratory investigation of water distribution among low albedo asteroids in the outer belt, using the 3-micron reflectance absorption of molecular H2O and structural OH ions, was conducted.

Ceres: Evolution and current state
TL;DR: In this article, the authors modeled several thermal evolution scenarios for Ceres to explore the nature of large, wet protoplanets and to predict current-day evidence that might be found by close inspection, such as by the Dawn mission.

Ceres’ evolution and present state constrained by shape data
TL;DR: In this article, the role played by hydrothermal activity in the long-term evolution of Ceres and especially the evolution of its hydrosphere was investigated, and it was shown that shape data can help constrain the amount of hydrated silicate in the core, and thus the extent of Hydrothermal Activity in Ceres.
