SPHERE’s detailed images of dusty rings around young stars offer a rare glimpse into the hidden machinery of planet formation. These bright arcs and faint clouds reveal where tiny planet-building ...
Studying the orbits of thousands of exoplanets shows that large planets tend to have elliptical orbits, while smaller planets tend to have more circular orbits. This split coincides with several other ...
The coincidence of trends in abundance, metallicity and eccentricity points to two distinct pathways for forming small and large planets. "To see a transition in the eccentricities of the orbits at ...
