CASTAway: An asteroid main belt tour and survey [PDF]

Advances in Space Research, 2018
CASTAway is a mission concept to explore our Solar System's main asteroid belt. Asteroids and comets provide a window into the formation and evolution of our Solar System and the composition of these objects can be inferred from space-based remote sensing using spectroscopic techniques.

The Mid-plane of the Main Asteroid Belt [PDF]

The Astronomical Journal, 2018
Abstract We measure the mid-plane of the main asteroid belt by using the observational data of a nearly complete and unbiased sample of asteroids and find that it has inclination and longitude of ascending node

A record of planet migration in the main asteroid belt [PDF]

Nature, 2009
The main asteroid belt lies between the orbits of Mars and Jupiter, but the region is not uniformly filled with asteroids. There are gaps, known as the Kirkwood gaps, in the asteroid distribution in distinct locations that are associated with orbital resonances with the giant planets; asteroids placed in these locations follow chaotic orbits and escape

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 ...

The first confirmation of V-type asteroids among the Mars crosser population [PDF]

, 2014
The Mars crossing region constitutes a path to deliver asteroids from the Inner Main Belt to the Earth crossing space. While both the Inner Main Belt and the population of Earth crossing asteroids contains a significant fraction of asteroids belonging to

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 ...

A ring as a model of the main belt in planetary ephemerides [PDF]

, 2010
We assess the ability of a solid ring to model a global perturbation induced by several thousands of main-belt asteroids. The ring is first studied in an analytical framework that provides an estimate of all the ring's parameters excepting mass.

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 ...
