SIOS Lab graduate student, Colby Merrill, contributed to work that models the formation scenario of Dinkinesh’s strange satellite, Selam! The contact binary shape of Selam is likely a result of smaller moonlets merging at speeds near their escape velocities. This
JASS Article Published
Event-Based Sensor Noise Modeling for Space-Based Space Domain Awareness, led by Dr. Rachel Oliver, has been published in the Journal of Astronautical Sciences. This work presents the most detailed, physics-based, end-to-end model for event-based vision sensors observing space objects created
SIOSlab Contributes to Studies of Dimorphos’s Ejecta Features
As a member of the NASA/DART team, SIOSlab graduate student Colby Merrill contributed to work that was recently published in Nature Communications! The two articles focus on the morphology and evolution of ejecta created by the DART impact and how
We Found the Dynamical Age of Selam
Selam (pictured below) is the strange secondary of the Dinkinesh binary asteroid system in the main-belt. Using the secular theory based on binary-Yarkovsky-O’Keefe-Radzievskii-Paddack (BYORP) and tides, we were able to constrain the age of this asteroid to 1-10 million years.
