The discoveries, published in the Astrophysical Journal, provide a better understanding of the way hydrogen gas from the protoplanetary disk is
incorporated into the star.
By coupling both Keck telescopes on Mauna Kea in Hawaii with a specifically engineered instrument named ASTRA (ASTrometric and phase-Referenced
Astronomy), Eisner and his colleagues were able to peer deeply into protoplanetary disks -- swirling clouds of gas and dust that feed the growing star
in its center and eventually coalesce into planets and asteroids to form a solar system.
