New Recurrently Active Main-belt Comet 2010 LH15
Colin Orion Chandler, William J. Oldroyd, Henry H. Hsieh +9
We announce the discovery of a main-belt comet (MBC), 2010 LH15 (alternately designated 2010 TJ175). MBCs are a rare type of main-belt asteroid that display comet-like activity, su…
Observational Characterization of Main-Belt Comet and Candidate Main-Belt Comet Nuclei
Henry H. Hsieh, Marco Micheli, Michael S. P. Kelley +9
We report observations of nine MBCs or candidate MBCs, most of which were obtained when the targets were apparently inactive. We find effective nucleus radii (assuming albedos of p…
New Active Asteroid 2015 VA108: A Citizen Science Discovery
Colin Orion Chandler, William J. Oldroyd, Chadwick A. Trujillo +6
We announce the discovery of activity, in the form of a distinct cometary tail, emerging from main-belt asteroid 2015 VA108. Activity was first identified by volunteers of the Citi…
Discovery of Dust Emission Activity Emanating from Main-belt Asteroid 2015 FW412
Colin Orion Chandler, Chadwick A. Trujillo, William J. Oldroyd +6
We present the discovery of activity emanating from main-belt asteroid 2015 FW412, a finding stemming from the Citizen Science project Active Asteroids, a NASA Partner program. We…
A Targeted Search for Main Belt Comets
Léa Ferellec, Colin Snodgrass, Alan Fitzsimmons +6
Main Belt Comets (MBCs) exhibit sublimation-driven activity while occupying asteroid-like orbits in the Main Asteroid Belt. MBCs and candidates show stronger clustering of their lo…
Photometric and dynamic characterisation of active asteroid (248370) 2005 QN173
Bojan Novakovic, Debora Pavela, Henry H. Hsieh +1
We present the physical and dynamical properties of the recently discovered active asteroid (248370) 2005 QN173 (aka 433P). From our observations, we derived two possible rotation…
