Thermography of Asteroid and Future Applications in Space Missions
Applied Sciences, 2020 The Near-Earth Asteroid 162173 Ryugu is a C-type asteroid which preserves information about the ancient Solar System and is considered enriched in volatiles such as water and organics associated with the building blocks of life, and it is a potentially ...

Near-Earth Objects in the Taurid complex [PDF]
Monthly Notices of the Royal Astronomical Society, 2008 The Taurid complex consists of many substreams and has both comet 2P/Encke and several Near-Earth Objects (NEOs) moving within it. We conduct a new search for associated NEOs, investigate the orbital evolution of any identified NEO and search for meteor showers associated with these NEOs.

Visible Spectroscopic Observations of a Near-Earth Object, 2012 DA14 [PDF]
, 2013 We present visible spectroscopic observations of a near-earth object (NEO), 2012 DA(14). The asteroid 2012 DA(14) came close to the Earth's surface on 2013 February 15 at a distance of 27700 km. Its estimated diameter is similar to 45 m.

Population Ecology, EarlyView.This study examines the demographic dynamics of two seabird populations on Tromelin Island, 15 years after the eradication of brown rats. The results indicate that these populations are in good health and are expected to continue growing until breeding sites are saturated in about a century.

The unpredictably eruptive dynamics of spruce budworm populations in eastern Canada
Population Ecology, EarlyView.We examine historical population data for spruce budworm from several locations through the period 1930–1997, and use density‐dependent recruitment curves to test whether the pattern of population growth over time is more consistent with Royama's (1984; Ecological Monographs 54:429–462) linear R(t) model of harmonic oscillation at Green River New ...

Origin and dynamics of Near Earth Objects
Comptes Rendus. Physique, 2005 Abstract The population of Near-Earth Objects (NEOs) evolves on orbits which can cross the orbit of the Earth. Most NEOs come from the asteroid belt via unstable zones associated with powerful or diffusive resonances. Their evolutionary paths and the statistical properties of their dynamics have been determined by massive numerical integrations.
