Main-belt Asteroids in the K2 Uranus Field [PDF]
The Astrophysical Journal Supplement Series, 2018 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 ...

A photometric search for active Main Belt asteroids [PDF]
Astronomy & Astrophysics, 2014 It is well known that some Main Belt asteroids show comet-like features. A representative example is the first known Main Belt comet 133P/(7968) Elst-Pizarro. If the mechanisms causing this activity are too weak to develop visually evident comae or tails,

Distant Formation and Differentiation of Outer Main Belt Asteroids and Carbonaceous Chondrite Parent Bodies [PDF]
AGU Advances, 2022 Volatile compositions of asteroids provide information on the Solar System history and the origins of Earth's volatiles. Visible to near‐infrared observations at wavelengths of 4) and low temperatures (10 au) and could be transported to their current ...

A Population of Comets in the Main Asteroid Belt [PDF]
Science, 2006 Comets are icy bodies that sublimate and become active when close to the Sun. They are believed to originate in two cold reservoirs beyond the orbit of Neptune: the Kuiper Belt (equilibrium temperatures of ∼40 kelvin) and the Oort Cloud (∼10 kelvin).

Taxonomy and Light-curve Data of 1000 Serendipitously Observed Main-belt Asteroids [PDF]
Astrophysical Journal Supplement Series, 2018 We present VRI spectrophotometry of 1003 main-belt asteroids (MBAs) observed with the Sutherland, South Africa node of the Korea Microlensing Telescope Network (KMTNet).

Numerical simulations suggest asteroids (101955) Bennu and (162173) Ryugu are likely second or later generation rubble piles [PDF]
Nature CommunicationsRubble pile asteroids are widely understood to be composed of reaccumulated debris following a catastrophic collision between asteroids in the main asteroid belt, where each disruption can make a family of new asteroids.

Polarimetric survey of main-belt asteroids [PDF]
, 2017 Aims. We present the 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 ...

HIGH ECLIPTIC LATITUDE SURVEY FOR SMALL MAIN-BELT ASTEROIDS [PDF]
, 2013 Main-belt asteroids have been continuously colliding with one another since they were formed. Its size distribution is primarily determined by the size dependence of asteroid strength against catastrophic impacts.

Low-thrust tour of the main belt asteroids [PDF]
Advances in Space Research, 2016 This work presents some initial results on a possible low-thrust tour of the main asteroid belt. The asteroids are visited through a series of fly-by’s to be completed within a given time-frame and limit on the mass of the spacecraft at launch. The asteroids to be visited are automatically selected out of a large database of possible candidates.
