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 find that main-belt asteroid P/2013 R3 consists of 10 or more distinct components, the largest up to 200?m in radius (assumed geometric albedo of 0.05) each of which produces a coma and comet-like dust tail. A diffuse debris cloud with total mass ~2 ? 108?kg further envelopes the entire system. The… Expand

The Nucleus of Active Asteroid 311P/(2013 P5) PANSTARRS
The unique inner-belt asteroid 311P/PANSTARRS (formerly P/2013 P5) is notable for its sporadic, comet-like ejection of dust in nine distinct epochs spread over $\sim$250 days in 2013. This curiousExpand
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
FAST ROTATION AND TRAILING FRAGMENTS OF THE ACTIVE ASTEROID P/2012 F5 (GIBBS)*
While having a comet-like appearance, P/2012 F5 (Gibbs) has an orbit native to the Main Asteroid Belt, and physically is a km-sized asteroid which recently (mid 2011) experienced an impulsive massExpand
Dust loss from activated asteroid P/2015 X6
We present observations and dust tail models of activated asteroid P/2015 X6 from deep imaging data acquired at the 10.4m Gran Telescopio Canarias (GTC) from mid-December 2015 to late January 2016.Expand
The nucleus of main-belt Comet P/2010 R2 (La Sagra)
Abstract We present recent observations of main-belt comet P/2010 R2 (La Sagra) obtained using the Gemini North telescope on five nights in late 2011 and early 2013 during portions of the object’sExpand
Comet 66P/du Toit: not a near Earth main belt comet
Main belt comets (MBCs) are a peculiar class of volatile-containing objects with comet-like morphology and asteroid-like orbits. However, MBCs are challenging targets to study remotely due to theirExpand
Split Active Asteroid P/2016 J1 (PANSTARRS)
We present a photometric and astrometric study of the split active asteroid P/2016 J1 (PANSTARRS). The two components (hereafter J1-A and J1-B) separated either ~1500 days (2012 May to June) or 2300Expand
X-shooter search for outgassing from Main Belt Comet P/2012 T1 (Pan-STARRS)
Main Belt Comets are a recently identified population of minor bodies with stable asteroid-like orbits but cometary appearances. Sublimation of water ice is the most likely mechanism for theirExpand
Post-main-sequence debris from rotation-induced YORP break-up of small bodies
Although discs of dust and gas have been observed orbiting white dwarfs, the origin of this circumstellar matter is uncertain. We hypothesize that the in situ break-up of small bodies such asExpand
Hubble and Keck Telescope Observations of Active Asteroid 288P/300163 (2006 VW139)
We present Hubble Space Telescope (HST) and Keck 10 m telescope observations of active asteroid 288P/300163 (2006 VW139) taken to examine ejected dust. The nucleus is a C-type object with absoluteExpand

Hubble Space Telescope observations of main-belt comet P/2013 P5 reveal an extraordinary system of six dust tails that distinguish this object from any other. Observations two weeks apart showExpand
HUBBLE SPACE TELESCOPE OBSERVATIONS OF MAIN-BELT COMET (596) SCHEILA
We present Hubble Space Telescope Observations of (596) Scheila during its recent dust outburst. The nucleus remained point-like with absolute magnitude HV = 8.85 ± 0.02 in our data, equal to theExpand
The Active Asteroids
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-beltExpand
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
HST and VLT Investigations of the Fragments of Comet C/1999 S4 (LINEAR)
TLDR
At least 16 fragments were detected in images of comet C/1999 S4 (LINEAR) taken on 5 August 2000 with the Hubble Space Telescope and on 6 August with the Very Large Telescope, which implies that the total mass in the observed fragments was about 2 × 109 kilograms. Expand
Interpretation of (596) Scheila's Triple Dust Tails
Strange-looking dust cloud around asteroid (596) Scheila was discovered on 2010 December 11.44-11.47. Unlike normal cometary tails, it consisted of three tails and faded within two months. WeExpand
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
Distribution and properties of fragments and debris from the split Comet 73P/Schwassmann-Wachmann 3 as revealed by Spitzer Space Telescope
During 2006 Mar - 2007 Jan, we used the IRAC and MIPS instruments on the Spitzer Space Telescope to study the infrared emission from the ensemble of fragments, meteoroids, and dust tails in the moreExpand
Impact-triggered breakup of comet C/1999 S4 (LINEAR): Identification of the closest intersecting orbits of other small bodies with its orbit
As we are still not certain of the causes of the splitting of comet C/1999 S4 (LINEAR), we attempt to explain the initiation and/or triggering of the breakup of the nucleus of this comet byExpand
Effect of rotational disruption on the size–frequency distribution of the Main Belt asteroid population
The size distribution of small asteroids in the Main Belt is assumed to be determined by an equilibrium between the creation of new bodies out of the impact debris of larger asteroids and theExpand
