New Active Asteroid 313P/Gibbs
David Jewitt, Jessica Agarwal, Nuno Peixinho +5
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 obje…
Episodic Ejection from Active Asteroid 311P/PANSTARRS
David Jewitt, Jessica Agarwal, Harold Weaver +2
We examine the development of the active asteroid 311P/PANSTARRS (formerly, 2013 P5) in the period from 2013 September to 2014 February using high resolution images from the Hubble…
Image Enhancement Techniques for Quantitative Investigations of Morphological Features in Cometary Comae: A Comparative Study
Nalin Samarasinha, Stephen Larson
Many cometary coma features are only a few percent above the ambient coma (i.e., the background) and therefore coma enhancement techniques are needed to discern the morphological s…
Disintegrating Asteroid P/2013 R3
David Jewitt, Jessica Agarwal, Jing Li +3
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 Te…

David Jewitt, Masateru Ishiguro, Harold Weaver +3
We report new observations of the prototype main-belt comet (active asteroid) 133P/Elst-Pizarro taken at high angular resolution using the Hubble Space Telescope. The object has th…
