We are participating in a Danish-led satellite mission that will dramatically strengthen our understanding of stars. The satellite will observe oscillations by measuring tiny fluctuations in stellar brightness that are undetectable from the ground because of the effects of the Earth's atmosphere. The oscillation frequencies will allow us to probe in exquisite detail the interiors of nearby stars and study phenomena that do not occur in the Sun. We will also continue our pioneering work on ground-based oscillation measurements and cement a long-term collaboration between Australia and Denmark that will provide opportunities for young researchers to gain international experience.

我们正在参与丹麦领导的卫星任务，这将极大地加强我们对恒星的了解。 该卫星将通过测量恒星亮度的微小波动来观察振荡，由于地球大气层的影响，这些波动在地面上是无法检测到的。 振荡频率将使我们能够详细地探测附近恒星的内部并研究太阳中不会发生的现象。 我们还将继续在地面振荡测量方面的开拓性工作，并巩固澳大利亚和丹麦之间的长期合作，这将为年轻研究人员提供获得国际经验的机会。
