TL;DR: In this article, an analysis of ground-based thermal IR observations of 1 Ceres and 2 Pallas has yielded a new value for the IR beaming parameter employed in the standard asteroid thermal emission model which is significantly lower than the previous one.
Journal ArticleDOI
Systematic biases in radiometric diameter determinations
TL;DR: In this article, a disk-integrated beaming parameter of 0.72 was determined for the moon and used to correct empirically for the roughness effects in thermophysical models; the standard thermal model was found to systematically underestimate cold object diameters, while overstating their albedos.
Journal ArticleDOI
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.
Journal ArticleDOI
The 1.7- to 4.2-μm spectrum of asteroid 1 Ceres: Evidence for structural water in clay minerals
TL;DR: A high-resolution Fourier spectrum (1.7-3.5 microns) and medium-resolution spectrophotometry (2.7 -2.8 micron) were obtained for Asteroid 1 Ceres as mentioned in this paper.
Journal ArticleDOI
The Nature of M-Class Asteroids from 3-μm Observations☆
TL;DR: In this paper, the authors used spectrophotometrically observed twenty M-class asteroids in the 1.2-to 3.5-μm region, sixteen of them for the first time, and found that over 35% of them have absorption features at 3 μm diagnostic of water of hydration.
