ALMA Reveals Lives of Planet-Forming Disks

The AGE-PRO collaboration, bringing together astronomers from Europe, America, and Asia, has unveiled news constraints on the evolution of dust and gas in protoplanetary disks thanks to an ambitious ALMA program targeting 30 sources. Through combined analyses of dust thermal emission and gas spectral lines, it appears that the gas reservoir available to form giant planets evolves more slowly than the dust reservoir.
 

AS was notably responsible for the interpretation of the observational results concerning the gas. In particular, we showed that the observations favored a model of disk evolution controlled by magnetized disk winds, with strong implications for planet formation and migration. The next step for the collaboration is the analysis of JWST MIRI spectra to establish a comprehensive view of disk evolution, including the inner regions where most planets form.
