Orbital motion of the HR8799 system
The HR 8799 system harbors four super-Jupiters orbiting with periods that range from decades to centuries. HR 8799e is the innermost planet in this video.
This footage consists of 7 images of HR 8799 taken with the Keck Telescope over 7 years. The video was made by Jason Wang, data was reduced by Christian Marois, and the orbits were fit by Quinn Konopacky. Bruce Macintosh, Travis Barman, and Ben Zuckerman assisted in the observations.Källa:
