研究人员开发了一种新的机器学习模型，用于估算系外行星的光合作用宜居带（PHZ），摆脱了以地球为中心的假设。该无偏模型基于基本的热力学和氧化还原化学原理，将光合作用模拟为一种通用的光化学反应。该模型预测，光合作用生物可以通过进化出更大的光收集结构来适应较低的恒星通量，从而将光合作用的潜力扩展到先前估算的范围之外。 AI
影响 这项研究可以通过识别更多潜在宜居的系外行星来改进对外星生命的搜寻。

The search for exoplanet biosignatures is guided by whether planetary environments can sustain photosynthesis. As such, the Photosynthetic Habitable Zone (PHZ) was recently proposed, as the overlap between the canonical habitable zone and the orbital range where stellar irradianc…
