The Yarkovsky Drift's Influence on NEAs: Trends and Predictions with NEOWISE Measurements [PDF]

, 2012
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 predictions for 540 near-Earth asteroids (NEAs) out of the current sample of \sim

Constraining the Limitations of NEATM-like Models: A Case Study with Near-Earth Asteroid (285263) 1998 QE2

The Planetary Science Journal, 2023
Near-Earth asteroids (NEAs) are a key test bed for investigations into planet formation, asteroid dynamics, and planetary defense initiatives. These studies rely on understanding NEA sizes, albedo distributions, and regolith properties.

The Size Distribution of Near-Earth Objects Larger Than 10 m [PDF]

, 2017
We analyzed data from the first year of a survey for Near-Earth Objects (NEOs) that we are carrying out with the Dark Energy Camera (DECam) on the 4 m Blanco telescope at the Cerro Tololo Inter-American Observatory.

Physical Characterization of Warm Spitzer-observed Near-Earth Objects [PDF]

, 2012
Near-infrared spectroscopy of Near-Earth Objects (NEOs) connects diagnostic spectral features to specific surface mineralogies. The combination of spectroscopy with albedos and diameters derived from thermal infrared observations can increase the ...

Photometric observations of 9 Near-Earth Objects [PDF]

, 2001
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.

A Constellation of MicroSats to Search for NEOs

, 2018
Large or even medium sized asteroids impacting the Earth can cause damage on a global scale. Existing and planned concepts for finding near-Earth objects (NEOs) with diameter of 140 m or larger would take ~15-20 years of observation to find ~90% of them.

Easily retrievable objects among the NEO population [PDF]

, 2013
Asteroids and comets are of strategic importance for science in an effort to understand the formation, evolution and composition of the Solar System. Near-Earth Objects (NEOs) are of particular interest because of their accessibility from Earth, but also

Toward a European Facility for Ground-Based Radar Observations of Near-Earth Objects

Remote Sensing, 2023
In this work, we present the preliminary results of radar observations of Near-Earth Objects (NEOs) carried out by European radio telescopes in the framework of the European Space Agency (ESA) project “NEO observation concepts for radar systems”, aimed ...

Photometric survey of 67 near-Earth objects [PDF]

Astronomy & Astrophysics, 2018
Context. The near-Earth object (NEO) population is a window into the original conditions of the protosolar nebula, and has the potential to provide a key pathway for the delivery of water and organics to the early Earth.

ExploreNEOs VIII: Dormant Short-Period Comets in the Near-Earth Asteroid Population [PDF]

, 2015
We perform a search for dormant comets, asteroidal objects of cometary origin, in the near-Earth asteroid (NEA) population based on dynamical and physical considerations.
