Extended photometric survey of near-Earth objects [PDF]
Astronomy & Astrophysics, 2020 Context. The near-Earth objects (NEOs), whose proximity makes them the most accessible bodies in the Solar System, allow us to sample asteroids from tens of kilometers down to objects of a few meters in size. However, while the physical properties for the largest bodies are mostly known, we have very little physical information regarding the small NEOs.

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

A Single Ejection Model of the DART/Dimorphos Debris Trail
The 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.

Constraining the Shape Distribution of Near-Earth Objects from Partial Light Curves [PDF]
Astronomical Journal, 2019 In the absence of dense photometry for a large population of near-Earth objects (NEOs), the best method of obtaining a shape distribution comes from sparse photometry and partial light curves.

The study of near Earth objects and meteor showers
Journal of Physics: Conference Series, 2020 In this work, the physical parameters of near-Earth objects (NEO), i.e. small celestial bodies crossing the Earth’s orbit, are investigated. First of all, the study of NEO, whose number exceeds 15 thousand, is important in terms of asteroid threats.

Preatmospheric Detection of a Meter-sized Earth Impactor
The Planetary Science Journal, 2023 On 2020 September 18 U.S. Government (USG) sensors detected a bolide with peak bolometric magnitude of −19 over the Western Pacific. The impact was also detected by the Geostationary Lightning Mapper instrument on the GOES-17 satellite and infrasound ...

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

A differential algebra-based importance sampling method for impact probability computation on Earth resonant returns of near-Earth objects [PDF]
Monthly notices of the Royal Astronomical Society, 2018 A differential algebra based importance sampling method for uncertainty propagation and impact probability computation on the first resonant returns of Near Earth Objects is presented in this paper.

Identifying near-Earth object families
Icarus, 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.
