Asteroseismology uses sounds in stars to probe their interiors. Just as ultrasound is used to see the face of a foetus before it is born, astronomers can 'see' inside the stars by studying their light variations caused by pulsations within them. This research will provide unprecedent 3D views of the pulsation modes and abundance distributions in the rapidly oscillating peculiar A stars.

星震学利用恒星中的声音来探测其内部。正如超声波用于在胎儿出生前观察其面部一样，天文学家可以通过研究恒星内部脉动引起的光变化来“看到”恒星内部。这项研究将为快速振荡的奇特 A 星的脉动模式和丰度分布提供前所未有的 3D 视图。
