【摘要】：正在太陽系外找到一顆適合人類居住的行星,是天體物理學(xué)家長期以來的夢想。適合人類居住,通常要求有液態(tài)水,這相應(yīng)地要求:行星到母恒星的距離在一定的范圍之內(nèi)。按照最近Dumusque等在Nature周刊發(fā)表的研究報告,事情或許有了一定的眉目。研究者宣稱,發(fā)現(xiàn)了一顆類地球太陽系外行星,它圍繞半人馬座α雙星之一(B星)運轉(zhuǎn),半人馬座α雙星屬于最接近太陽系的恒星,離我們僅4光年遠。
[Abstract]:It has long been the dream of astrophysicists to find a planet suitable for human habitation outside the solar system. Suitable for human habitation, liquid water is usually required, which requires that the distance from the planet to the parent star is within a certain range. According to a recent study published by Dumusque et al. In Nature Weekly, things may have some eyebrows. The researchers claim to have discovered an Earth-like extrasolar planet orbiting one of the 偽-binary stars in the constellation Sagittarius, a star closest to the solar system, just four light-years away.
