A trio of researchers with the European Southern Observatory and Université Côte d’Azur has found evidence showing that the gas and dust disks that form around early stars systems do not contain enough material to form the planets that develop. In their paper published in the journal Astronomy Astrophysics, Carlo Manara, A. Morbidelli and T. Guillot describe their study of data from the Atacama Large Millimeter Array (ALMA) in Chile and what they found.
