有希望的格利泽 12 b
一颗岩石地球大小的系外行星,气候温和,离我们相对较近?这似乎好得不像真的,但这可能就是格利泽12 b。由 Masayuki Kuzuhara、Akihiko Fukui 及其同事,以及 Shishir Dholakia、Larissa Palethorpe 及其同事在同一天发表的两篇论文中同时宣布,格利泽 12 b 有望成为一颗标杆行星。格利泽 12 b 的信号最早是由 Transiting Exoplanets Survey Satellite(TESS)发现的,该卫星在 2021 年 8 月至 10 月间观测到了它的恒星--一颗距离我们只有 12 皮秒的 M-矮星。这两个团队使用了一系列令人印象深刻的其他地基和天基望远镜来验证这颗行星的存在,并通过自适应光学成像、光度测量和光谱学来完善其特性。数据集的相互吻合度很高,显示这是一颗0.9-1.0地球半径的行星,质量可能略大于地球(尽管不确定性仍然很大):\({1.57}_{-0.75}^{+0.78}\)地球质量),围绕恒星运行 12.76 天。假设其反照率为地球,那么它的平衡温度为287开氏度,这使得格利泽12 b完全处于温热状态,刚好位于经典 "宜居带 "的内侧。

期刊介绍: Nature Astronomy, the oldest science, has played a significant role in the history of Nature. Throughout the years, pioneering discoveries such as the first quasar, exoplanet, and understanding of spiral nebulae have been reported in the journal. With the introduction of Nature Astronomy, the field now receives expanded coverage, welcoming research in astronomy, astrophysics, and planetary science. The primary objective is to encourage closer collaboration among researchers in these related areas. Similar to other journals under the Nature brand, Nature Astronomy boasts a devoted team of professional editors, ensuring fairness and rigorous peer-review processes. The journal maintains high standards in copy-editing and production, ensuring timely publication and editorial independence. In addition to original research, Nature Astronomy publishes a wide range of content, including Comments, Reviews, News and Views, Features, and Correspondence. This diverse collection covers various disciplines within astronomy and includes contributions from a diverse range of voices.
