By developing state-of-the-art stellar atmosphere and evolution models, the project will endeavour to answer some of the key outstanding questions in stellar astrophysics including how magnetic fields are manifested in stars, how stars are affected by convection, how oscillations are excited in stars and how old the most ancient stars in the Milky Way are. The project will endeavour to make obsolete the free parameters that have hampered stellar modelling for the past half-century. Using unique stellar models the project aims to provide rich legacy resources for countless studies in modern astronomy and provide the necessary theoretical underpinning for ambitious Australian-led Milky Way surveys, such as GALAH and SkyMapper, and international satellite missions such as Kepler, TESS and PLATO.

通过开发最先进的恒星大气和演化模型，该项目将致力于回答恒星天体物理学中的一些关键悬而未决的问题，包括恒星中的磁场是如何表现出来的，恒星是如何受到对流影响的，恒星中的振荡是如何激发的，以及银河系中最古老的恒星的年龄。该项目将努力使过去半个世纪阻碍恒星建模的自由参数过时。使用独特的恒星模型，该项目旨在为现代天文学中的无数研究提供丰富的遗产资源，并为澳大利亚领导的雄心勃勃的银河系调查，如GALAH和SkyMapper，以及国际卫星任务，如开普勒，TESS和柏拉图提供必要的理论基础。
