Stars are born through the collapse of clouds in interstellar space. A by-product of the collapse is a flattened ring of gas in orbit about the newly-formed star. Eventually planets form within the ring and a planetary system is born. Magnetic forces in the clouds are strong, and so are expected to significantly affect these processes. This project aims to understand the role of magnetic fields in the formation of stars and planetary systems in order to develop accurate models that can be used to interpret observations by planned national and international astronomical facilities. The truly international nature of astronomy will allow us to enhance Australia's research visibility overseas.

恒星是通过星际空间中的云层坍塌而诞生的。坍塌的一个副产品是围绕这颗新形成的恒星的轨道上的扁平的气体环。最终，行星在环内形成，一个行星系统诞生了。云层中的磁力很强，因此预计会对这些过程产生重大影响。该项目旨在了解磁场在恒星和行星系统形成中的作用，以便开发可用于解释计划中的国家和国际天文设施观测的准确模型。天文学真正的国际性将使我们能够提高澳大利亚在海外的研究知名度。
