An investigation by Argentine astronomers analyzed the importance of the dust that surrounds stars, in a process known as planetary migration, which could incorporate into planetary formation models "an ingredient that is relevant and that until now had not been taken into account." into account," the specialists said. This is a team of Argentine astronomers, two of them based in Denmark and Chile; and the other two working as Conicet researchers at the Institute of Astrophysics, in La Plata, who focused their study on the role of dust in an important process known as planetary migration, that is, the change in the orbit of the planets motivated by the forces of its environment. The work was recently published in the prestigious scientific journal The Astrophysical Journal.
