Polarimetric survey of main-belt asteroids [PDF]

Astronomy & Astrophysics, 2017
Aims.We present the results of a polarimetric survey of main-belt asteroids at Complejo Astronómico El Leoncito (CASLEO), San Juan, Argentina. The aims of this survey are to increase the database of asteroid polarimetry and to estimate the diversity in the polarimetric properties of asteroids.Methods.The survey began in 1995 and a second period began ...

Gaia and IRTF abundance of A-type main-belt asteroids

Astronomy & Astrophysics
Context. The so-called missing-mantle problem is a long-standing issue in planetary science. It states that olivine-rich asteroids should be abundant in the main belt, while this is observationally found not to be the case by dedicated surveys ...

The Distribution of Highly Red-sloped Asteroids in the Middle and Outer Main Belt [PDF]

The Planetary Science Journal
Red ( S > 10%/0.1 μ m) spectral slopes are common among Centaurs and trans-Neptunian objects (TNOs) in the outer solar system. Interior to and co-orbital with Jupiter, the red ( S ∼ 10%/0.1 μ m) slopes of D-type main-belt and Jupiter Trojan asteroids are

Candidate Main-belt Asteroids for Surface Heterogeneity

The Astronomical Journal
Large terrestrial bodies in our solar system like the Earth, Mars, Mercury, and the Moon exhibit geologically complex surfaces with compositional heterogeneity.

Accessibility of the resources of near Earth space using multi-impulse transfers [PDF]

, 2010
Most future concepts for exploration and exploitation of space require a large initial mass in low Earth orbit. Delivering this mass requires overcoming Earth's natural gravity well, which imposes a distinct obstacle to space-faring.

Main-belt Asteroids in the K2 Uranus Field [PDF]

The Astrophysical Journal Supplement Series, 2018
Abstract We present the K2 light curves of a large sample of untargeted main-belt asteroids (MBAs) detected with the Kepler Space Telescope. The asteroids were observed within the Uranus superstamp, a relatively large, continuous field with a low stellar background designed to cover the planet Uranus and its moons during Campaign 8 of ...

MAIN BELT ASTEROIDS WITHWISE/NEOWISE. I. PRELIMINARY ALBEDOS AND DIAMETERS [PDF]

, 2011
We present initial results from the Wide-field Infrared Survey Explorer (WISE), a four-band all-sky thermal infrared survey that produces data well suited for measuring the physical properties of asteroids, and the NEOWISE enhancement to the WISE mission

Thermal Properties of 1847 WISE-observed Asteroids

The Planetary Science Journal, 2022
We present new thermophysical model fits of 1847 asteroids, deriving thermal inertia, diameter, and Bond and visible geometric albedo. We use thermal flux measurements obtained by the Wide-field Infrared Survey Explorer (WISE) during its fully cryogenic ...

Asteroid deflection and exploitation : possible synergies [PDF]

, 2011
The asteroid and cometary impact hazard has long been recognised as an important issue requiring risk assessment and contingency planning. At the same time asteroids have also been acknowledged as possible sources of raw materials for future large-scale ...

V-type asteroids in the middle main belt [PDF]

Icarus, 2008
The recent discovery of the first V-type asteroid in the middle belt, (21238) 1995WV7, located at ~2.54 AU, raises the question of whether it came from (4) Vesta or not. In this paper, we present spectroscopic observations indicating the existence of another V-type asteroid at ~2.53 AU, (40521) 1999RL95, and we investigate the possibility that these ...
