Infrared Lightcurves of Near Earth Objects [PDF]
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 Telescope, many of them having no previously reported rotation periods.

EXPLORENEOs. I. DESCRIPTION AND FIRST RESULTS FROM THE WARMSPITZERNEAR-EARTH OBJECT SURVEY [PDF]
We have begun the ExploreNEOs project in which we observe some 700 Near Earth Objects (NEOs) at 3.6 and 4.5 microns with the Spitzer Space Telescope in its Warm Spitzer mode.

Internal structure of Near-Earth Objects [PDF]
Abstract For the purposes of mitigation, the internal structure of near-Earth objects (NEOs) remains one of the most important but least understood parameters. From a science point of view, the internal structure is equally intriguing. Knowledge of the internal structure can reveal the collisional history, and in the case of comets, may also reveal ...

Unconfirmed Near-Earth Objects [PDF]
Abstract We studied the Near-Earth Asteroid (NEA) candidates posted on the Minor Planet Center’s Near-Earth Object Confirmation Page (NEOCP) between years 2013 and 2016. Out of more than 17000 NEA candidates, while the majority became either new discoveries or were associated with previously known objects, about 11% were unable to be ...

Are Near Earth Objects the Key to Optimization Theory? [PDF]
This note suggests that near earth objects and Central Force Optimization have something in common, that NEO theory may hold the key to solving some vexing problems in deterministic optimization: local trapping and proof of convergence. CFO analogizes Newton's laws to locate the global maxima of a function.

First Results from the Rapid-response Spectrophotometric Characterization of Near-Earth Objects Using RATIR [PDF]
As part of our multi-observatory, multi-filter campaign, we present \rmi color observations of 82 Near-Earth Objects (NEOs) obtained with the RATIR instrument on the 1.5m robotic telescope at the San Pedro Martir's National Observatory in Mexico.

Photometric observations of 9 Near-Earth Objects [PDF]
We present new CCD observations of nine Near-Earth Asteroids carried out between February, 1999 and July, 2000. The bulk of the data was acquired through an R_C filter, while the minor planet 11405 was observed without filter.

Source regions of carbonaceous meteorites and near-Earth objects
Context. The source regions of ordinary chondrites (~80% of all falls) and large S-type near-Earth objects (NEOs; ~30%) have recently been identified with three young asteroid families (Karin, Koronis, Massalia) being at the origin of most ordinary chondrite falls. Aims.

Comets in the near-Earth object population [PDF]
Abstract Because the lifespan of near-Earth objects (NEOs) is shorter than the age of the Solar System, these objects originate elsewhere. Their most likely sources are the main asteroid belt and comets. Through physical observations we seek to identify potential dormant or extinct comets among “asteroids” catalogued as NEOs and thereby determine the
