Rice Uni Assistant Professor Andrea Isella presented images of binary system HD 142527 by Atacama Large Millimeter/submillimeter Array (ALMA) radio telescope at the annual meeting of the American Association for the Advancement of Science in Washington, D.C. The system has long been known to harbor a planet-forming corona of dust and gas, but ALMA images are providing more detail than ever and allowing for better analysis of the system’s contents and mechanics.
