Characterization of Active Main Belt Object P/2012 F5 (Gibbs): A Possible Impacted Asteroid
R. Stevenson, E. A. Kramer, J. M. Bauer +2
In this work we characterize the recently discovered active main belt object P/2012 F5 (Gibbs), which was discovered with a dust trail > 7' in length in the outer main belt, 7 mont…
Revising the age for the Baptistina asteroid family using WISE/NEOWISE data
Joseph R. Masiero, A. K. Mainzer, T. Grav +2
We have used numerical routines to model the evolution of a simulated Baptistina family to constrain its age in light of new measurements of the diameters and albedos of family mem…
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…
Further Defining Spectral Type "Y" and Exploring the Low-mass End of the Field Brown Dwarf Mass Function
J. Davy Kirkpatrick, Christopher R. Gelino, Michael C. Cushing +12
We present the discovery of another seven Y dwarfs from the Wide-field Infrared Survey Explorer (WISE). Using these objects, as well as the first six WISE Y dwarf discoveries from…
A T8.5 Brown Dwarf Member of the Xi Ursae Majoris System
Edward L. Wright, M. F. Skrutskie, J. Davy Kirkpatrick +12
The Wide-field Infrared Survey Explorer has revealed a T8.5 brown dwarf (WISE J111838.70+312537.9) that exhibits common proper motion with a solar-neighborhood (8 pc) quadruple sta…
