类似早期太阳系的恒星系统现身

  据英国《独立报》3日报道,美国天文学家们宣称,他们发现了一个距离太阳系很近且“极为类似”的恒星系统,该恒星系统将有助于我们理解地球及其他邻近行星的形成历程。

  在最新研究中,科学家们使用了美国国家航空航天局(NASA)的“红外天文学平流层观测台(SOFIA)”拍摄的数据。他们从该望远镜拍摄的遥远恒星的图片细节中,挑选出了与这颗恒星有关的红外数据。

  研究表明,这颗看起来类似太阳的恒星是波江座第五恒星(Epsilon Eridani),年龄仅为太阳的五分之一,距离地球约10光年,是所有包含“年轻版太阳”的星系中离地球最近的,因此,有助于我们研究太阳的演化历程。

  论文作者、天文学家马西莫·马伦戈表示:“波江座第五恒星拥有一套行星系统,其行星系统目前正经历巨大的变动。太阳系年轻的时候也发生过这些巨大的变动,彼时,月球上的环形山已形成大半;地球上的水汇聚成海洋;地球的宜居环境也已被‘设置’好。”

  他们发现,这颗恒星被一个内盘和一个外盘环绕,两盘之间存在一个似乎由行星造成的巨大鸿沟。马伦戈解释说:“我们现在能很自信地说,这颗恒星的内带和外带被分开,中间的裂缝很有可能由行星造成。我们迄今还没有探测到这些行星,但我们确信它们存在,将于2018年10月发射的詹姆斯·韦伯望远镜或许能看见它们。研究这些行星将有助于我们进一步了解地球以及周围行星的遥远过去。”
