It is surprising that stars, the basic building blocks of galaxies, are not better characterised. Nailing with high accuracy the basic stellar fundamentals - masses, radii, effective temperatures and luminosities - across the whole range of different stellar types requires the precise, high-resolution, observational data that the Sydney University Stellar Interferometer (SUSI) was designed to provide. Operational with the highest resolution ever attained, the instrument is poised to make inroads into stellar astrophysics. The synthesis of SUSI data with complementary data from national and international collaborators is an exciting prospect for the solution of crucial problems in contemporary astrophysics.

令人惊讶的是，恒星，星系的基本组成部分，没有得到更好的描述。 高精度地确定不同恒星类型的整个范围内的基本恒星基本要素-质量，半径，有效温度和光度-需要悉尼大学恒星干涉仪（SUSI）设计提供的精确，高分辨率的观测数据。 该仪器以有史以来最高的分辨率运行，有望进入恒星天体物理学领域。 SUSI数据与来自国家和国际合作者的补充数据的合成是解决当代天体物理学关键问题的令人兴奋的前景。
