资源简介:
We present a nearly complete rapid neutron-capture process (r-process) chemical inventory of the metal-poor ([Fe/H]=-1.46+/-0.10) r-process-enhanced ([Eu/Fe]=+1.32+/-0.08) halo...
本研究提供了一套近乎完整的快中子俘获过程(rapid neutron-capture process,简称r-过程)化学丰度编目,其研究对象为贫金属([Fe/H]=-1.46±0.10)且r-过程增强([Eu/Fe]=+1.32±0.08)的银晕星
