一位独立研究者用 Claude Code 在 NASA 的 TESS 数据中发现一颗此前未见报告的候选行星，该数据自 2018 年起就存在。Claude Code 配合 Opus 5.5 和 Fable 5.1 完成了大部分工作，包括解析光变曲线、编写凌星搜索、拟合凌星、检查邻近恒星和次食，研究者负责设定问题和通过/失败规则。

An independent researcher used Claude Code to find a possible new planet. It had been sitting in NASA's TESS data since 2018, and he could find no earlier report of it.
Claude Code with Opus 5.5 and Fable 5.1 did most of the work: parsing the light curves, writing the transit search, fitting transits, checking nearby stars and secondary eclipses. He set the questions and the pass/fail rules.
The star is about 116 light-years away. Every 3.18 days it dims by about 0.05% for two hours, which fits a planet about 1.4 times the size of Earth. It is still a candidate, and TESS will check it again from Oct 31 to Nov 26.
