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 scattering cross-section ~1.4 times larger than that of the nucleus, corresponding to a dust mass of Md ~ 3 × 107 kg. V–R color measurements indicate that both the nucleus and dust are redder than the Sun, with no significant color differences between the dust cloud's northern and southern plumes. We also… Expand

Comet 66P/du Toit: not a near-Earth main belt comet
Context. Main belt comets (MBCs) are a peculiar class of volatile-containing objects with comet-like morphology and asteroid-like orbits. However, MBCs are challenging targets to study remotely dueExpand

A recent disruption of the main-belt asteroid P/2010 A2
TLDR
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. Expand
