Can Cyclonic Vortices Halt the Inward Migration of Low-Mass Planets?

The birth of planets is a cosmic dance, intricately choreographed by the forces of gravity, gas, and dust. Protoplanetary discs, which are massive spinning clouds of gas and dust surrounding young stars, are the birthplaces of planets. These discs are dynamic environments where newly forming planets move and interact in fascinating ways. A recent study by Chametla and colleagues dives into the specifics of how low-mass planets (with masses between 1 and 15 times that of Earth) move within these gaseous discs, particularly focusing on how these movements are influenced by gaps and vortices within the disc.
