Amanda Karakas
澳洲蒙納許大學物理與天文學學院副教授
Associate Professor, School of Physics and Astronomy Monash University, Australia
Amanda的主要研究領域是類太陽的低質量與中等質量恆星的演化與核合成,以及星系中元素的起源。元素的起源與恆星演化過程密切相關,恆星演化描述了恆星如何因核聚變而隨時間發生變化。 她的研究重點之一是恆星內部重元素(即比鐵更重的元素)生成的奧秘。雖然天文學家已能解釋大多數自然界元素的起源,但產生這些重元素的恆星類型仍存在很大的不確定性,特別是在早期宇宙中。Karakas 教授的研究專注於低質量與中等質量恆星在這一過程中所扮演的角色。
Amanda’s primary area of research interest is in the evolution and nucleosynthesis of sun-like low and intermediate-mass stars and the origin of elements in galaxies. The story of the origin of the elements is intimately tied to the processes of stellar evolution, which describes how stars change with time as a result of nuclear fusion. One focus of her research is the intriguing mystery of the production of heavy elements in stars, that is, elements heavier than iron. While astronomers can explain the origin of most of the elements in nature, the type of the stars that produced the heavy elements is still highly uncertain, especially in the early Universe. Prof. Karakas’ research has been focused on the role that low and intermediate-star stars play in this story.
