现在,科学家利用来自NASA斯皮策太空望远镜的数据表明,其中一些行星是如此炽热,以至于它们基本上在自行分解甚至自我撕裂。
根据发表在《天体物理学杂志快报》上的这项研究,被称为KELT-9b的超热木星行星的面向恒星侧的氢分子被其恒星流出的强烈热量撕裂了,这些分子直到绕回星球的阴暗面后才能重新形成。
芝加哥大学的主要作者梅根·曼斯菲尔德(Megan Mansfield)在一份报告中介绍,还有其他一些热木星和超热木星,它们虽然不那么热,但仍然足够温暖,以至于发生上述怪异的运动。
像KELT-9b这样的行星并不十分常见,这可能是因为它们所处的极端条件。在这种情况下,超热的木星每半个地球日绕其轨道运行一次。那是恒星与行星之间不可思议的紧密关系,目前尚不清楚这类行星本质被零碎分解之前可以存在多长时间。
