Physical Parameters of Asteroids Estimated from the WISE 3 Band Data and NEOWISE Post-Cryogenic Survey
A. Mainzer, T. Grav, J. Masiero +7
Enhancements to the science data processing pipeline of NASA's Wide-field Infrared Explorer (WISE) mission, collectively known as NEOWISE, resulted in the detection of 158,000 m…
Preliminary Analysis of WISE/NEOWISE 3-Band Cryogenic and Post-Cryogenic Observations of Main Belt Asteroids
Joseph R. Masiero, A. K. Mainzer, T. Grav +4
We present preliminary diameters and albedos for 13511 MBAs that were observed during the 3-Band Cryo phase of the WISE survey (after the outer cryogen tank was exhausted) and as p…
WISE/NEOWISE Observations of the Jovian Trojan Population: Taxonomy
Tommy Grav, Amy K. Mainzer, James M. Bauer +2
We present updated/new thermal model fits for 478 Jovian Trojan asteroids observed with the Wide-field Infrared Survey Explorer (WISE). Using the fact that the two shortest bands u…
The Yarkovsky Drift's Influence on NEAs: Trends and Predictions with NEOWISE Measurements
C. R. Nugent, A. Mainzer, J. Masiero +2
We used WISE-derived geometric albedos (p_V) and diameters, as well as geometric albedos and diameters from the literature, to produce more accurate diurnal Yarkovsky drift predict…
Characterizing Subpopulations within the Near Earth Objects with NEOWISE: Preliminary Results
A. Mainzer, T. Grav, J. Masiero +10
We present the preliminary results of an analysis of the sub-populations within the near-Earth asteroids, including the Atens, Apollos, Amors, and those that are considered potenti…
Detection of Semi-Major Axis Drifts in 54 Near-Earth Asteroids: New Measurements of the Yarkovsky Effect
C. R. Nugent, J. L. Margot, S. R. Chesley +1
We have identified and quantified semi-major axis drifts in Near-Earth Asteroids (NEAs) by performing orbital fits to optical and radar astrometry of all numbered NEAs. We focus on…
