The Rotation Axes of Stars tell us about how they were Born

Numerical simulation of the fragmentation of a cluster of stars up to the formation of stars (left) with a zoom on the most central part of the cluster (right). The inclination axes of the masses similar to those observed by the Kepler satellite (in cluster NGC 6791) align in this simulation when the kinetic energy of the original cloud is comparable to the ambient turbulent energy. © E.Corsaro & Y.-N Lee

Using asteroseismology, an international team including CEA, CNRS and Université Grenoble-Alpes discovered a surprising alignment of the rotation axes of stars in open clusters, shedding light on the conditions in which stars are formed in our galaxy...
