What to know about Astronomers discover how to estimate masses of newborn planets using dust rings

Astronomers from the University of Warwick, MIT, and McMaster University have developed a method to estimate the mass of newborn planets by analyzing the properties of dust rings in protoplanetary disks. The team validated their simulation-based approach using the PDS 70 system and applied it to data from the exoALMA survey.

Astronomers discover how to estimate masses of newborn planets using dust rings Sadie Harley Scientific Editor Robert Egan Associate Editor A team of astronomers, led by University of Warwick in collaboration with researchers at MIT and McMaster, have…

Why it matters

Published in The Astrophysical Journal, this research offers astronomers a new way to find and characterize planets that are too deeply embedded in their birth environment to be seen directly.

Common ground

Swirling disks of gas and dust surrounding young stars are the environments in which planets form.

Perspective signals
