A Single Ejection Model of the DART/Dimorphos Debris Trail

open access: yesThe Astrophysical Journal Letters, 2023
The collision of the NASA DART spacecraft with asteroid Dimorphos resulted in the formation of a distinctive and long-lived debris trail, formed by the action of solar radiation pressure on ejected particles.

Measuring the Orbit Drift of Near-Earth Asteroids by the Yarkovsky Effect

open access: yesThe Astrophysical Journal, 2023
The Yarkovsky effect causes the semimajor axis drift of near-Earth asteroids. The drift can be detected by a precise orbit determination process. Using the proposed algorithm, 2233 out of 27,078 near-Earth asteroids are chosen as the initial candidates ...

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

open access: yes, 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.

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

open access: yes, 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.

Identifying near-Earth object families

open access: yesIcarus, 2005
The study of asteroid families has provided tremendous insight into the forces that sculpted the main belt and continue to drive the collisional and dynamical evolution of asteroids. The identification of asteroid families within the NEO population could provide a similar boon to studies of their formation and interiors.

WORKING GROUP: NEAR-EARTH OBJECTS [PDF]

open access: yesProceedings of the International Astronomical Union, 2011
Following its meeting in May, 2010, the IAU Executive Committee requested that a Working Group on NEOs within Div. III be re-activated and carry out the following activities: a) investigate and formulate requirements for an international ground- and/or space-based NEO survey, to detect, track and characterize (optical/IR, radar) 90% of all

Klet Observatory – European Contribution to Detecting and Tracking of Near Earth Objects

open access: yesGeoinformatics FCE CTU, 2012
Near Earth Object (NEO) research is an expanding field of astronomy. Is is important for solar system science and also for protecting human society from asteroid and comet hazard.  A near-Earth object (NEO) can be defined as an asteroid or comet that has

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

open access: yesAnnales 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.

Evidence-based robust design of deflection actions for near Earth objects [PDF]

open access: yes, 2012
This paper presents a novel approach to the robust design of deflection actions for Near Earth Objects (NEO). In particular, the case of deflection by means of Solar-pumped Laser ablation is studied here in detail. The basic idea behind Laser ablation is
