Interesting new study indicating that interstellar object ‘Oumuamua shows non-gravitational accelerations, most likely from cometary activity. A previous study stated an upper bound on dust ejection of ~1 gram/second based on an estimate of the coma detection limit.
Our group looks forward to studying the Ryugu samples when they return to Earth in late 2020. In the meantime, we are analyzing meteorite analogs to the Hayabusa2 samples.
We have just completed the new website. Enjoy!
