Subaru望远镜发现了一个外行星和棕矮星,这是美国航天局罗马空间望远镜的关键目标。 The Subaru Telescope discovered an exoplanet and brown dwarf, key targets for NASA’s Roman Space Telescope.

Mauna Kea的Subaru望远镜通过OASIS方案首次发现重大情况,查明了一种外行星,HIP 54515b和棕色矮星,HIP 71618B。 The Subaru Telescope on Mauna Kea has made its first major discoveries through the OASIS program, identifying an exoplanet, HIP 54515 b, and a brown dwarf, HIP 71618 B. 离Leo271光年远的地表板约是木星质量的18倍,是海王星距离的轨道。 The exoplanet, 271 light-years away in Leo, is about 18 times Jupiter’s mass and orbits at Neptune-like distance. 棕色矮星距离布特斯169光年, 大约是木星质量的60倍, 绕着年轻恒星运行。 The brown dwarf, 169 light-years away in Bootes, is roughly 60 times Jupiter’s mass and orbits a young star. 这些发现通过引力效应和直接成像得到证实,是美国航天局的第一批发现,为美国航天局即将推出的Nancy Grace Roman空间望远镜提供了关键目标,该望远镜将利用棕色矮星来测试像地球一样的行星成像技术。 These findings, confirmed via gravitational effects and direct imaging, are the first from OASIS and provide key targets for NASA’s upcoming Nancy Grace Roman Space Telescope, which will use the brown dwarf to test technology for imaging Earth-like planets.
