Using the Atacama Large Millimeter/submillimeter Array (ALMA), a science team including LPL professor Ilaria Pascucci and graduate student Dingshan Deng has for the first time traced the evolution of gas, providing the first measurements of gas disk masses and sizes across the lifetime of planet-forming disks.

Study led by LPL researcher Dr. Sam Crossley reveals a surprising new way planetary cores formed. The findings could reshape how scientists understand the early evolution of rocky planets like Mars.
