The Heterogeneous Surface of Asteroid (16) Psyche
Saverio Cambioni, Katherine de Kleer, Michael Shepard
Main-belt asteroid (16) Psyche is the largest M-type asteroid, a class of object classically thought to be the metal cores of differentiated planetesimals and the parent bodies of…
Asteroid 16 Psyche: Shape, Features, and Global Map
Michael K. Shepard, Katherine de Kleer, Saverio Cambioni +9
We develop a shape model of asteroid 16 Psyche using observations acquired in a wide range of wavelengths: Arecibo S-band delay-Doppler imaging, Atacama Large Millimeter Array (ALM…
Detection of Rotational Spectral Variation on the M-type asteroid (16) Psyche
Juan A. Sanchez, Vishnu Reddy, Michael K. Shepard +6
The asteroid (16) Psyche is of scientific interest because it contains ~ 1% of the total mass of the asteroid belt and is thought to be the remnant metallic core of a protoplanet.…
Detection of Water and/or Hydroxyl on Asteroid (16) Psyche
Driss Takir, Vishnu Reddy, Juan Sanchez +2
In order to search for evidence of hydration on M-type asteroid (16) Psyche, we observed this object in the 3 micron spectral region using the long-wavelength cross-dispersed (LXD:…
The Composition of M-type asteroids II: Synthesis of spectroscopic and radar observations
J. R. Neeley, B. E. Clark, M. E. Ockert-Bell +5
This work updates and expands on results of our long-term radar-driven observational campaign of main-belt asteroids (MBAs) focused on Bus-DeMeo Xc- and Xk-type objects (Tholen X a…
A study of asteroid pole-latitude distribution based on an extended set of shape models derived by the lightcurve inversion method
Josef Hanus, Josef Durech, Miroslav Broz +12
Tens of thousands of sparse-in-time lightcurves from astrometric projects are publicly available. We investigate these data and use them in the lightcurve inversion method to deriv…
