【摘要】：正在太阳系外找到一颗适合人类居住的行星,是天体物理学家长期以来的梦想。适合人类居住,通常要求有液态水,这相应地要求:行星到母恒星的距离在一定的范围之内。按照最近Dumusque等在Nature周刊发表的研究报告,事情或许有了一定的眉目。研究者宣称,发现了一颗类地球太阳系外行星,它围绕半人马座α双星之一(B星)运转,半人马座α双星属于最接近太阳系的恒星,离我们仅4光年远。
[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 伪-binary stars in the constellation Sagittarius, a star closest to the solar system, just four light-years away.
