NEOMOD: A New Orbital Distribution Model for Near-Earth Objects [PDF]

The Astronomical Journal, 2023
Near-Earth Objects (NEOs) are a transient population of small bodies with orbits near or in the terrestrial planet region. They represent a mid-stage in the dynamical cycle of asteroids and comets, which starts with their removal from the respective ...

Radar observability of near-Earth objects using EISCAT 3D [PDF]

Annales Geophysicae, 2020
Radar observations can be used to obtain accurate orbital elements for near-Earth objects (NEOs) as a result of the very accurate range and range rate measureables.

Infrared Lightcurves of Near Earth Objects [PDF]

Astrophysical Journal Supplement Series, 2018
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.

The Mission Accessible Near-Earth Objects Survey: Four years of photometry [PDF]

Astrophysical Journal Supplement Series, 2018
Over 4.5 years, the Mission Accessible Near-Earth Object Survey (MANOS) assembled 228 Near-Earth Object (NEO) lightcurves. We report rotational lightcurves for 82 NEOs, constraints on amplitudes and periods for 21 NEOs, lightcurves with no detected ...

ExploreNEOs I: Description and first results from the Warm Spitzer NEO Survey [PDF]

, 2010
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.

First Results from the rapid-response spectrophotometric characterization of Near-Earth Objects [PDF]

Astronomical Journal, 2019
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.

NEOWISE Observations of Near-Earth Objects: Preliminary Results [PDF]

, 2011
With the NEOWISE portion of the \emph{Wide-field Infrared Survey Explorer} (WISE) project, we have carried out a highly uniform survey of the near-Earth object (NEO) population at thermal infrared wavelengths ranging from 3 to 22 $\mu$m, allowing us to ...

The Population of Tiny Near-Earth Objects Observed by NEOWISE [PDF]

, 2013
Only a very small fraction of the asteroid population at size scales comparable to the object that exploded over Chelyabinsk, Russia has been discovered to date, and physical properties are poorly characterized.

THE MISSION ACCESSIBLE NEAR-EARTH OBJECTS SURVEY (MANOS): FIRST PHOTOMETRIC RESULTS [PDF]

, 2016
The Mission Accessible Near-Earth Objects Survey aims to physically characterize sub-km near-Earth objects (NEOs). We report the first photometric results from the survey that began in 2013 August.
