A Look at Eight Outbursts of Comet 7P/Pons-Winnecke

Ky Huynh, Michael S. P. Kelley, Jessica M. Sunshine +6

Cometary outbursts may be used as a means to infer the physical processes occurring on cometary nuclei. To that end, we studied eight outbursts of comet 7P/Pons-Winnecke identified…

Ejecta Evolution Following a Planned Impact into an Asteroid: The First Five Weeks

Theodore Kareta, Cristina Thomas, Jian-Yang Li +85

The impact of the DART spacecraft into Dimorphos, moon of the asteroid Didymos, changed Dimorphos' orbit substantially, largely from the ejection of material. We present results fr…

A LOOK at Outbursts of Comet C/2014 UN (Bernardinelli-Bernstein) Near 20 au

Michael S. P. Kelley, Rosita Kokotanekova, Carrie E. Holt +10

Cometary activity may be driven by ices with very low sublimation temperatures, such as carbon monoxide ice, which can sublimate at distances well beyond 20 au. This point is empha…

Seeing the Bigger Picture: The Rosetta Mission Amateur Observing Campaign and Lessons for the Future

Helen Usher, Colin Snodgrass, Simon F. Green +2

Amateur astronomers can make useful contributions to the study of comets. They add temporal coverage and multi-scale observations which can aid the study of fast-changing, and larg…
