Astronomers discover dimmest exoplanet via direct imaging

An international team of astronomers has discovered a third planet, Beta Pictoris d, orbiting the star Beta Pictoris. This newly found exoplanet is the dimmest ever detected via direct imaging from Earth and one of the smallest in mass. The discovery was made using data from the European Southern Observatory's Very Large Telescope, spanning over a decade of observations and published in The Astrophysical Journal Letters. AI

    Third planet found around Beta Pictoris, the faintest exoplanet discovered by direct imaging from the ground

    一个国际天文学家团队发现,恒星绘架座β星周围存在第三颗行星。这颗新发现的行星被命名为“绘架座β d”,其亮度仅为同一系统中首颗被发现行星绘架座β b的百分之一,是迄今利用地面望远镜直接成像发现的最暗系外行星,也是质量最小的系外行星之一。研究团队借助欧洲南方天文台甚大望远镜(VLT)发现了这颗行星,并在跨越十余年的历史观测数据中确认了它的存在。相关研究发表于最新一期《天体物理学杂志快报》。(科技日报)
