Some asteroids eject dust, unexpectedly producing transient, comet-like comae and tails. First ascribed to the sublimation of near-surface water ice, mass-losing asteroids (also called main-belt comets) can in fact be driven by a surprising diversity of mechanisms. In this paper, we consider 11 dynamical asteroids losing mass, in nine of which the ejected material is spatially resolved. We address mechanisms for producing mass loss including rotational instability, impact ejection… Expand

A binary main-belt comet
TLDR
The observations provide strong support forSublimation as the driver of activity in 288P and show that sublimation torques may play an important part in binary orbit evolution. Expand
A New Active Asteroid 313P/Gibbs
We present initial observations of the newly discovered active asteroid 313P/Gibbs (formerly P/2014 S4), taken to characterize its nucleus and comet-like activity. The central object has a radiusExpand
The unusual asteroid 2201 Oljato: Origins and possible debris trail
Abstract Potentially hazardous asteroid Oljato has a very eccentric low-inclination orbit of semimajor axis a 2.17 au, placing it just outside 4:1 resonance with Jupiter. Its association withExpand
LARGE PARTICLES IN ACTIVE ASTEROID P/2010 A2*
The previously unknown asteroid P/2010 A2 rose to prominence in 2010 by forming a transient, comet-like tail consisting of ejected dust. The observed dust production was interpreted as the result ofExpand
Nucleus and Mass Loss from Active Asteroid 313P/Gibbs
We present Hubble Space Telescope observations of active asteroid 313P/Gibbs (formerly P/2014 S4) taken over the five month interval from 2014 October to 2015 March. This object has been recurrentlyExpand
Disintegrating Asteroid P/2013 R3
Splitting of the nuclei of comets into multiple components has been frequently observed but, to date, no main-belt asteroid has been observed to break up. Using the Hubble Space Telescope, we findExpand
Origin and Evolution of Volatile-rich Asteroids
Volatile-rich asteroids represent the largest population, about 42% (DeMeo and Carry, 2014), of objects found between 2 and 3.5 AU. They encompass asteroids from the C complex that are believed toExpand
Nucleus of active asteroid 358P/Pan-STARRS (P/2012 T1)
The dust emission from active asteroids is likely driven by collisions, fast rotation, sublimation of embedded ice, and combinations of these. Characterising these processes leads to a betterExpand
Interplanetary Dust Particles as Samples of Icy Asteroids
Meteorites have long been considered as reflections of the compositional diversity of main belt asteroids and consequently they have been used to decipher their origin, formation, and evolution.Expand

A recent disruption of the main-belt asteroid P/2010 A2
TLDR
Observations of P/2010 A2, a previously unknown inner-belt asteroid with a peculiar, comet-like morphology, are reported, concluding that it is most probably the remnant of a recent asteroidal disruption in February/March 2009, evolving slowly under the action of solar radiation pressure. Expand
(596) SCHEILA IN OUTBURST: A PROBABLE COLLISION EVENT IN THE MAIN ASTEROID BELT
Images of asteroid (596) Scheila have been acquired at various dates after the discovery of the 2010 outburst. Assuming a short-duration event scenario, as suggested by the quick vanishing of theExpand
Collisional Excavation of Asteroid (596) Scheila
We observed asteroid (596) Scheila and its ejecta cloud using the Swift UV–optical telescope. We obtained photometry of the nucleus and the ejecta, and for the first time measured the asteroid’sExpand
A collision in 2009 as the origin of the debris trail of asteroid P/2010 A2
TLDR
It is determined that this was an asteroid collision that occurred around 10 February 2009 and can be explained by an initial impact ejecting large clumps of debris that disintegrated and dispersed almost immediately. Expand
OPTICAL AND DYNAMICAL CHARACTERIZATION OF COMET-LIKE MAIN-BELT ASTEROID (596) SCHEILA ∗
We present observations and a dynamical analysis of the comet-like main-belt object, (596) Scheila. V-band photometry obtained on UT 2010 December 12 indicates that Scheila's dust cloud has aExpand
Rotational breakup as the origin of small binary asteroids
TLDR
It is found that mass shed from the equator of a critically spinning body accretes into a satellite if the material is collisionally dissipative and the primary maintains a low equatorial elongation. Expand
A Population of Comets in the Main Asteroid Belt
TLDR
Optical data is presented showing the existence of a population of comets originating in a third reservoir: the main asteroid belt, which lends new support to the idea that main-belt objects could be a major source of terrestrial water. Expand
MAIN-BELT COMET P/2008 R1 (GARRADD)*
We present a study of the newly discovered main-belt comet P/2008 R1 (Garradd), an object with the dynamical characteristics of an asteroid and the physical characteristics of a comet. PhotometryExpand
Activity in Geminid Parent (3200) Phaethon
The asteroid (3200) Phaethon is widely recognized as the parent of the Geminid meteoroid stream. However, it has never shown evidence for ongoing mass loss or for any form of comet-like activity thatExpand
