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 the pre-outburst value, with no secondary fragments of diameter ⩾100 m (for assumed albedos 0.04). We find a coma having a peak scattering cross section ∼2.2×104 km2, corresponding to a mass in micron-sized particles of ∼4×107 kg. The particles are deflected by solar radiation pressure on projected spatial…

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 absolute

THE DUST ENVIRONMENT OF MAIN-BELT COMET P/2012 T1 (PANSTARRS)

The Main-Belt Comet P/2012 T1 (PANSTARRS) has been imaged using the 10.4 m Gran Telescopio Canarias and the 4.2 m William Herschel Telescope at six epochs in the period from 2012 November to 2013

THE DUST ENVIRONMENT OF MAIN-BELT COMET P/2010 R2 (LA SAGRA)

We present a model of the dust environment of Main-Belt Comet P/2010 R2 (La Sagra) from images acquired during the period 2010 October–2011 January. The tails are best simulated by anisotropic

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 find

Search for Dust Emission from (24) Themis Using the Gemini-North Observatory

We report the results of a search for a dust trail aligned with the orbit plane of the large main-belt asteroid (24) Themis, which has been reported to have water ice frost on its surface.

MAIN-BELT COMET P/2012 T1 (PANSTARRS)

We present initial results from observations and numerical analyses aimed at characterizing the main-belt comet P/2012 T1 (PANSTARRS). Optical monitoring observations were made between 2012 October

OBSERVATIONAL EVIDENCE FOR AN IMPACT ON THE MAIN-BELT ASTEROID (596) SCHEILA

An unexpected outburst was observed around (596) Scheila in 2010 December. We observed (596) Scheila soon after the impact using ground-based telescopes. We succeeded in the detection of a faint

A Short-duration Event as the Cause of Dust Ejection from Main-Belt Comet P/2012 F5 (Gibbs)

We present observations and an interpretative model of the dust environment of the Main-Belt Comet P/2010 F5 (Gibbs). The narrow dust trails observed can be interpreted unequivocally as an impulsive

(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 the

Predictions for Dusty Mass Loss from Asteroids During Close Encounters with Solar Probe Plus

The Solar Probe Plus (SPP) mission will explore the Sun’s corona and innermost solar wind starting in 2018. The spacecraft will also come close to a number of Mercury-crossing asteroids with

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.

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's

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.

Surveyor observations of lunar horizon-glow

Each of the Surveyor 7, 6, and 5 spacecraft observed a line of light along its western lunar horizon following local sunset. It has been suggested that this horizon-glow (HG) is sunlight, which is

The Lifetime of Ice on Main Belt Asteroids

We theoretically estimate the loss rate of buried ice from spherical bodies 2-3.3 AU from the Sun. The loss rate is explored as a function of about a dozen parameters. We introduce the concept of a

The Supplemental IRAS Minor Planet Survey

We present additional and revised IRAS diameters and albedos for the 1992 IRAS Minor Planet Survey (IMPS). Using orbital elements for 26,791 numbered asteroids, we found 2228 different multiply

The dynamics of larger interplanetary bodies is reviewed, with emphasis on evolutionary problems, interrelations, and open questions. Observational biases distinguishing the sample of known objects

On the absorption and scattering of light

When a beam of light passes through a material medium it suffers gradual extinction, mainly through molecular scattering, but partly also through conversion into heat. The two processes should be
