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 of either a hypervelocity impact with a smaller body or a rotational disruption. We have re-observed this object, finding that large particles remain a full orbital period after the initial outburst. In the intervening years, particles smaller than ~3?mm in radius have been dispersed by radiation… Expand

Anisotropic Ejection from Active Asteroid P/2010 A2: An Implication of Impact Shattering on an Asteroid
We revisited a mass ejection phenomenon that occurred in asteroid P/2010 A2 in terms of the dynamical properties of the dust particles and large fragments. We constructed a model assuming anisotropicExpand
Dynamics of Large Fragments in the Tail of Active Asteroid P/2010 A2
We examine the motions of large fragments at the head of the dust tail of the active asteroid P/2010 A2. In previous work, we showed that these fragments were ejected from the primary nucleus inExpand
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
New Observational Evidence of Active Asteroid P/2010 A2: Slow Rotation of the Largest Fragment
We report new observations of the active asteroid P/2010 A2 taken when it made its closest approach to the Earth (1.06 au in 2017 January) after its first discovery in 2010. Despite a crucial role ofExpand
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
A New Large Super-Fast Rotator: (335433) 2005 UW163
Asteroids of size larger than 150 m generally do not have rotation periods smaller than 2.2 hours. This spin cutoff is believed to be due to the gravitationally bound rubble-pile structures of theExpand
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
313 new asteroid rotation periods from Palomar Transient Factory observations
A new asteroid rotation period survey has been carried out by using the Palomar Transient Factory (PTF). Twelve consecutive PTF fields, which covered an area of 87 deg^2 in the ecliptic plane, wereExpand
The reactivation of main-belt Comet 324P/La Sagra (P/2010 R2)
We present observations using the Baade Magellan and Canada-France-Hawaii telescopes showing that main-belt comet 324P/La Sagra, formerly known as P/2010 R2, has become active again for the firstExpand
Formation and Evolution of Binary Asteroids
Satellites of asteroids have been discovered in nearly every known small body population, and a remarkable aspect of the known satellites is the diversity of their properties. They tell a story ofExpand


A recent disruption of the main-belt asteroid P/2010 A2
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
A collision in 2009 as the origin of the debris trail of asteroid P/2010 A2
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
P/2010 A2 LINEAR - II. Dynamical dust modelling
P/2010 A2 is an object on an asteroidal orbit that was observed to have an extended tail or debris trail in January 2010. In thi s work, we fit the outburst of P /2010 A2 with a conical burst model,Expand

P/2010 A2 LINEAR - I. An impact in the asteroid main belt
Comet P/2010 A2 LINEAR is an object on an asteroidal orbit within the inner Main Belt, therefore a good candidate for membership with the Main Belt Comet family. It was observed with severalExpand
Collisional balance of the meteoritic complex
Taking into account meteoroid measurements by in situ experiments, zodiacal light observations, and oblique angle hypervelocity impact studies, it is found that the observed size distributions ofExpand
Solar system object P/2010 A2 is the first-noticed example of the aftermath of a recently disrupted asteroid, probably resulting from a collision. Nearly a year elapsed between its inferredExpand

Dynamical Model for the Zodiacal Cloud and Sporadic Meteors
The solar system is dusty, and would become dustier over time as asteroids collide and comets disintegrate, except that small debris particles in interplanetary space do not last long. They can beExpand
