The Nature of Low-Albedo Small Bodies from 3-m Spectroscopy: One Group that Formed Within the Ammonia Snow Line and One that Formed Beyond It
Andrew S. Rivkin, Joshua P. Emery, Ellen S. Howell +9
We present evidence, via a large survey of 191 new spectra along with previously-published spectra, of a divide in the 3-m spectral properties of the low-albedo asteroid populat…
A new method for deriving composition of S-type asteroids from noisy and incomplete near-infrared spectra
Juan A. Sanchez, Cristina Thomas, Vishnu Reddy +3
The surface composition of S-type asteroids can be determined using band parameters extracted from their near-infrared (NIR) spectra (0.7-2.50 m) along with spectral calibration…
Remote-sensing Characterisation of Major Solar System Bodies with the Twinkle Space Telescope
Billy Edwards, Giorgio Savini, Giovanna Tinetti +4
Remote-sensing observations of Solar System objects with a space telescope offer a key method of understanding celestial bodies and contributing to planetary formation and evolutio…
Small Bodies Science with Twinkle
Billy Edwards, Sean Lindsay, Giorgio Savini +4
Twinkle is an upcoming 0.45m space-based telescope equipped with a visible and two near-infrared spectrometers covering the spectral range 0.4 to 4.5μm with a resolving power R~250…
Composition of Potentially Hazardous Asteroid (214869) 2007 PA8: An H Chondrite from the Outer Asteroid Belt
Juan A. Sanchez, Vishnu Reddy, Melissa Dykhuis +2
Potentially hazardous asteroids (PHAs) represent a unique opportunity for physical characterization during their close approaches to Earth. The proximity of these asteroids makes t…
Composition, Mineralogy, and Porosity of Multiple Asteroid Systems from Visible and Near-infrared Spectral Data
Sean S. Lindsay, Franck Marchis, Joshua P. Emery +2
We provide a taxonomic and compositional characterization of Multiple Asteroid Systems (MASs) located in the main belt (MB) using visible and near-infrared (0.45-2.5 um) spectral d…
Absorption Efficiencies of Forsterite. I: DDA Explorations in Grain Shape and Size
Sean S. Lindsay, Diane H. Wooden, David E. Harker +3
We compute the absorption efficiency (Qabs) of forsterite using the discrete dipole approximation (DDA) in order to identify and describe what characteristics of crystal grain shap…
