On 2019 January 5 a streamer associated with the 4–10 km main belt asteroid (6478) Gault was detected by the ATLAS sky survey, a rare discovery of activity around a main belt asteroid. Archival data from ATLAS and Pan-STARRS1 show the trail in early 2018 December, but not between 2010 and 2018 January. The feature has significantly changed over one month, perfectly matching predictions of pure dust dynamical evolution and changes in the observing geometry for a short release of dust around 2018… 
New active asteroid (6478) Gault
Main-belt asteroid (6478) Gault was observed to show cometary features in early 2019. To investigate the cause, we conducted BVR observations at Xingming Observatory, China, from 2019 January to
Dust properties of double-tailed active asteroid (6478) Gault
Context. Asteroid (6478) Gault was discovered to exhibit a comet-like tail in observations from December 2018, becoming a new member of the so-called active asteroid population in the main asteroid
Rotational Mass Shedding from Asteroid (6478) Gault
The ∼4 km diameter main belt asteroid 6478 Gault has ejected dust intermittently since at least 2013. The character of the emission, including its episodic nature and the low speed of the ejected
(6478) Gault: physical characterization of an active main-belt asteroid
In 2018 December, the main-belt asteroid (6478) Gault was reported to display activity. Gault is an asteroid belonging to the Phocaea dynamical family and was not previously known to be active, nor
Episodically Active Asteroid 6478 Gault
We present imaging and spectroscopic observations of 6478 Gault, a ∼6 km diameter inner main-belt asteroid currently exhibiting strong, comet-like characteristics. Three distinct tails indicate that
Active Asteroid (6478) Gault: A Blue Q-type Surface below the Dust?
We present near-infrared spectroscopy of the sporadically active asteroid (6478) Gault collected on the 3 m NASA/Infrared Telescope Facility observatory in late 2019 March/early April. Long-exposure
Physical characterization of the active asteroid (6478) Gault
We report dense light-curve photometry, BVRc colours and phase–mag curve of (6478) Gault, an active asteroid with sporadic comet-like ejection of dust. We collected optical observations along the
Physical Characterization of Active Asteroid (6478) Gault
Main belt asteroid (6478) Gault has been dynamically linked with two overlapping asteroid families: Phocaea, dominated by S-type asteroids, and Tamara, dominated by low-albedo C-types. This object
Time-series and Phase-curve Photometry of the Episodically Active Asteroid (6478) Gault in a Quiescent State Using APO, GROWTH, P200, and ZTF
We observed the episodically active asteroid (6478) Gault in 2020 with multiple telescopes in Asia and North America and found that it is no longer active after its recent outbursts at the end of
Recurrent Activity from Active Asteroid (248370) 2005 QN173: A Main-belt Comet
We present archival observations of main-belt asteroid (248370) 2005 QN173 (also designated 433P) that demonstrate this recently discovered active asteroid (a body with a dynamically asteroidal orbit


Multiple Outbursts of Asteroid (6478) Gault
Main-belt asteroid (6478) Gault unexpectedly sprouted two tails in late 2018 and early 2019, identifying it as a new active asteroid. Here we present observations obtained by the 1.2 m Zwicky
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 ∼250 days in 2013. This curious
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 several
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 a
Continued activity in P/2013 P5 PANSTARRS - Unexpected comet, rotational break-up, or rubbing binary asteroid?
The object P/2013 P5 PANSTARRS was discovered in August 2013, displaying a cometary tail, but its orbital elements indicated that it was a typical member of the inner asteroid main belt. We monitored
The Dust Environment of Comet 67P/Churyumov-Gerasimenko
Comet 67P/Churyumov-Gerasimenko passed its last perihelion on August 2002 and was well observed from fall 2002 to spring 2003. Its most prominent feature was a bright thin dust tail, which is best
We present a physical characterization of comet 176P/LINEAR, the third discovered member of the new class of main-belt comets, which exhibit cometary activity but are dynamically indistinguishable
In Situ Dust Measurements From within the Coma of 1P/Halley: First-Order Approximation with a Dust Dynamical Model
In situ measurements of the light locally scattered by cometary dust, as well as the local dust spatial density, are only available for one comet, 1P/Halley. These data were returned from the Optical

THE YARKOVSKY AND YORP EFFECTS: Implications for Asteroid Dynamics
The Yarkovsky and YORP (Yarkovsky-O’Keefe-Radzievskii-Paddack) effects are thermal radiation forces and torques that cause small objects to undergo semimajor axis drift and spin vector modifications,
