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 ...

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 ...

Space Weathering in the Main Asteroid Belt: The Big Picture [PDF]

The Astrophysical Journal, 2006
The optical properties of silicate-rich asteroidal surfaces (namely, S-complex asteroids) evolve over time under the influence of several processes, known as "space weathering" (SW), and are amply analyzed in laboratory experiments. A first estimate of the spectral reddening rate, due to SW, on family S-type main-belt asteroids (MBAs; Jedicke et al ...

Dynamical evolution of basaltic asteroids outside the Vesta family in the inner main belt [PDF]

, 2023
Basaltic V-type asteroids are leftovers from the formation and evolution of differentiated planetesimals. They are thought to originate from mantles and crusts of multiple different parent bodies. Identifying the links between individual V-type asteroids

Masses of asteroids and total mass of the main asteroid belt [PDF]

Proceedings of the International Astronomical Union, 2015
AbstractAn estimation of the mass of the main asteroid belt was made on the basis of the new version of EPM2014 ephemerides of the Institute of Applied Astronomy of Russian Academy of Sciences using about 800000 positional observations of planets and spacecraft.

Polarimetric survey of main-belt asteroids [PDF]

Astronomy & Astrophysics, 2011
Aims. We present the first results of a polarimetric survey of main-belt asteroids at Complejo Astronomico El Leoncito (Casleo), San Juan, Argentina. The aims of this survey are to increase the database of asteroid polarimetry, to estimate diversity in polarimetric properties of asteroids that belong to different taxonomic classes, and to search for ...

Characterization of V-type asteroids orbiting in the middle and outer main belt [PDF]

, 2021
We present new spectral observations using ground-based telescopes of 23 putative V-type asteroids, selected according to colour surveys in the visible from the Moving Objects Catalogue of the Sloan Digital Sky Survey and near-infrared from the Moving ...

Active asteroids: mystery in the Main Belt [PDF]

Proceedings of the International Astronomical Union, 2005
Classically, comets from the outer solar system (beyond the orbit of Neptune), are expected to be icy, and thus active near the Sun, while asteroids in the inner solar system (interior to the orbit of Jupiter) are expected to be relatively ice-deficient, and thus inert.

Thermal properties of large main-belt asteroids observed by Herschel PACS [PDF]

, 2020
Non-resolved thermal infrared observations enable studies of thermal and physical properties of asteroids via thermo-physical models provided the shape and rotational properties of the target are well determined.
