论文摘要
第一代恒星非常独特。金属的缺失可能会影响其形成，目前的模型表明，比我们今天所观察到的最高的初始质量分数要高得多，并且它们的其他某些特性（例如旋转速率和二进制）在很大程度上是未知或受直接观察的限制。但是，由于没有金属的缺乏，即使是给定质量的非旋转单星，也会有很大的变化：恒星将一直保持紧凑，直到它们死亡，氢富含氢的后，后来在半径上比现代恒星更深入了十个teem。当它们以超新星的爆炸爆炸时，对超新星中微子通量的暴露会大大增强，从而使锂的产生大量产生。对于所有恒星而言，这种生产不会恒定，而在整个质量范围内都大大不同。这种生产更多的挑战挑战了恶劣的高原的存在。
The first generation of stars is quite unique. The absence of metals likely affects their formation, with current models suggesting a much more top-heavy initial mass fraction than what we observe today, and some of their other properties, such as rotation rates and binarity, are largely unknown or constrained by direct observations. But even non-rotation single stars of a given mass will evolve quite differently due to the absence of the metals: the stars will mostly remain much more compact until their death, with the hydrogen-rich later reaching down ten teems deeper in radius then in modern stars. When they explode as supernovae, the exposure to the supernova neutrino flux is much enhanced, allowing for copious production of lithium. This production will not be constant for all stars but largely vary across the mass range. Such production even more challenges the presence of the Spite Plateau.
