奥利弗·盖恩是昴星望远镜和亚利桑那大学的天文学家。

Guyon said the usual thinking is that most planets form by the slow growth of solids onto a rocky core.

盖恩表示，通常认为大多数行星是由固体缓慢生长到岩石核心上形成的。

" This process cannot form giant planets at large orbital distance, so this discovery challenges our understanding of planet formation, " Guyon said.

盖恩表示，“这个过程无法在大轨道距离上形成巨行星，因此这一发现挑战了我们对行星形成的理解。”
