This project aims to measure the wobble in the position of distant stars that is caused by massive objects, using telescopes in space. This project expects to generate new knowledge on how binary stars, exoplanets, and stellar mass black holes are formed. Expected outcomes of this project include tight constraints on binary star models, new discoveries of neutron stars and black holes that are a few times more massive than the Sun, and samples of stars that do, and do not, host exoplanets. This should provide significant benefits including a catalogue of companion properties for billions of sources, new understanding of how stars die, as well as the first control sample of stars without planets to help understand how and why planets form.

该项目旨在使用太空望远镜测量由大质量物体引起的遥远恒星位置的摆动。该项目预计将产生关于双星，系外行星和恒星质量黑洞如何形成的新知识。该项目的预期成果包括严格限制双星星星模型，新发现中子星和质量比太阳大几倍的黑洞，以及有和没有系外行星的恒星样本。这应该会带来重大的好处，包括数十亿个来源的伴星属性目录，对恒星如何死亡的新理解，以及第一个没有行星的恒星控制样本，以帮助理解行星如何以及为什么形成。
