Providing the initial mass function of the first-generation stars of the universe with a peculiar chemical abundance pattern of metal-poor stars

确定典型质量（即，初始质量函数），这些恒星不含重元素，称为第三星族星，因为这些恒星影响第一星系的形成和早期宇宙的演化。在本研究中，我们模拟了大质量恒星的超新星爆炸，以预测喷出物的丰度模式。通过比较模型的预测和观测到的模式，我们估计第一恒星的典型质量为20- 50 M。

It is critically important to determine the typical mass (i.e., Initial Mass Function) of the First Stars in the Universe, which contain no heavy elements called Population III stars, because those stars affect the formation of First galaxies and evolution of early Universe. In the present study, we simulated the supernova explosion of massive stars to predict the abundance patterns of ejecta. By comparing the model prediction and the observed patterns, we estimated that the typical masses of First Stars are 20-50M.
