Sublimation Origin of Active Asteroid P/2018 P3
Yoonyoung Kim, Jessica Agarwal, David Jewitt +4
Active asteroids show (typically transient) cometary activity, driven by a range of processes. A sub-set, sometimes called main-belt comets, may be driven by sublimation and so cou…
Hubble Space Telescope Observations of Active Asteroid 324P/La Sagra
David Jewitt, Jessica Agarwal, Harold Weaver +3
Hubble Space Telescope observations of active asteroid 324P/La Sagra near perihelion show continued mass loss consistent with the sublimation of near-surface ice. Isophotes of the…
A serendipitous all sky survey for bright objects in the outer solar system
M. E. Brown, M. E. Bannister, B. P. Schmidt +9
We use seven year's worth of observations from the Catalina Sky Survey and the Siding Spring Survey covering most of the northern and southern hemisphere at galactic latitudes high…
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…
