The Wisconsin Atomic Transition Probability (WATP) program on Fe-group ions will be continued under this award. The primary objective of this work is to produce a tightly defined Fe-group elemental abundance pattern in low metallicity (old) stars. This Fe-group abundance pattern will provide a powerful constraint on models of supernovae and will improve understanding of the Galactic chemical evolution. The Broader Impact of the WATP program of quantitative spectroscopy will extend to fields such as lighting research and fusion plasma physics. The program will continue to pay special attention to recruiting and retaining students from underrepresented groups in astronomy, astrophysics, and physics. Outreach activities will include presentations to elementary school students.

关于铁族离子的威斯康星原子跃迁概率 (WATP) 计划将在该奖项下继续进行。这项工作的主要目标是在低金属丰度（老）恒星中产生严格定义的 Fe 族元素丰度模式。这种铁族丰度模式将为超新星模型提供强有力的约束，并将增进对银河系化学演化的理解。 WATP 定量光谱学计划的更广泛影响将扩展到照明研究和聚变等离子体物理等领域。 该项目将继续特别关注招募和留住天文学、天体物理学和物理学领域代表性不足群体的学生。外展活动将包括向小学生进行演讲。
