Spitzer Albedos of Near-Earth Objects
Annika Gustafsson, David E. Trilling, Michael Mommert +6
Thermal infrared observations are the most effective way to measure asteroid diameter and albedo for a large number of near-Earth objects. Major surveys like NEOWISE, NEOSurvey, Ex…
Infrared Lightcurves of Near Earth Objects
Joseph L. Hora, Amir Siraj, Michael Mommert +9
We present lightcurves and derive periods and amplitudes for a subset of 38 near earth objects (NEOs) observed at 4.5 microns with the IRAC camera on the the Spitzer Space Telescop…
The Science Case for an Extended Spitzer Mission
Jennifer C. Yee, Giovanni G. Fazio, Robert Benjamin +45
Although the final observations of the Spitzer Warm Mission are currently scheduled for March 2019, it can continue operations through the end of the decade with no loss of photome…
NEOSurvey 1: Initial results from the Warm Spitzer Exploration Science Survey of Near Earth Object Properties
David E. Trilling, Michael Mommert, Joseph Hora +6
Near Earth Objects (NEOs) are small Solar System bodies whose orbits bring them close to the Earth's orbit. We are carrying out a Warm Spitzer Cycle 11 Exploration Science program…
The Discovery of Cometary Activity in Near-Earth Asteroid (3552) Don Quixote
Michael Mommert, Joseph L. Hora, Alan W. Harris +8
The near-Earth object (NEO) population, which mainly consists of fragments from collisions between asteroids in the main asteroid belt, is thought to include contributions from sho…
