Astronomy: Giant planet seeks nursery place
Artie P. Hatzes1 & Günther Wuchterl2
Abstract
A further discovery of a planet in a binary star system — this time close in — could prove a problem for accepted theories of planetary formation. The implication is that there are more planets out there than we thought.
The first discovery ten years ago of 'Pegasi' planets1 — giant planets 100 times closer to their star than the Solar System's giant planets are to the Sun — shook long-held conceptions of planetary-system formation, which took the Solar System as a template. To square the new observations with the conventional model, some astronomers adopted theories of violent planetary migrations, in which the planets move around after they form.
