论文摘要
在这里，我们报告了用彗星二级离子质量分析仪（COSIMA）仪器在Rosetta Spacecraft上板上测量的67p/Churyumov-Gerasimenko收集的固体颗粒中的磷和氟的检测。我们已经从提出的COSIMA质谱中检测到含磷的矿物质，并且可以排除例如磷灰石矿物作为磷的来源。该结果完成了对固体彗星物质中生命中不必要的chnop元素的检测，这表明彗星传递是这些元素向年轻地球的潜在来源。还用源自彗星灰尘的CF $^+$辅助离子检测到氟。
Here, we report the detection of phosphorus and fluorine in solid particles collected from the inner coma of comet 67P/Churyumov-Gerasimenko measured with the COmetary Secondary Ion Mass Analyser (COSIMA) instrument on-board the Rosetta spacecraft, only a few kilometers away from the comet nucleus. We have detected phosphorus-containing minerals from the presented COSIMA mass spectra, and can rule out e.g. apatite minerals as the source of phosphorus. This result completes the detection of life-necessary CHNOPS-elements in solid cometary matter, indicating cometary delivery as a potential source of these elements to the young Earth. Fluorine was also detected with CF$^+$ secondary ions originating from the cometary dust.
