Summary

[edit]
Description
English: In a recently published paper, NOAO astronomer Joan Najita was part of a team that has shown evidence for a planet forming in the disk around a young star. The results provide perhaps the first evidence that planets are surrounded by a circumplanetary disk at birth. This figure is an artist’s conception of the young massive star HD100546 and its surrounding disk. A planet forming in the disk has cleared the disk within 13 AU of the star, a distance comparable to that of Saturn from the sun. As gas and dust flows from the circumstellar disk to the planet, this material surrounds the planet as a circumplanetary disk (inset). These rotating disks are believed to be the birthplaces of planetary moons, such as the Galilean moons that orbit Jupiter.
