Planetary Group Seminar: A Multi-instrument Study of a Cometary Outburst (J. Agarwal)
Abstract: On 2016 July 3, when comet 67P was already at 3.32 AU from the sun outbound from perihelion, several instruments on board Rosetta witnessed a small outburst of activity from a point on the surface emerging from the night's shadow. The dust plume above the surface was observed by OSIRIS and Alice, and the ejected material was detected in situ by COSIMA, GIADA, ROSINA, and the Startracker camera. This talk presents a summary and synthesis of the measurements, and discusses their implications for the properties of the ejected material and the process leading to this event.
