A Southwest Research Institute scientist contributed to a new solar system formation model that explains the existing inner planetary distribution and the asteroid belt between the inner and outer solar system. The team based the model on the first image collected by the Atacama Large Millimeter/submillimeter Array (ALMA) observatory, which shows a disk around a young star as a nested structure of rings.
