For the first time scientists have been able to prove a decades old theory on stars thanks to a revolutionary high-speed camera. Scientists at the University of Sheffield have been working with HiPERCAM, a high-speed, multicolour camera, which is capable of taking more than 1,000 images per second, allowing experts to measure both the mass and the radius of a cool subdwarf star for the first time.
The findings published today (8 April 2019) in Nature Astronomy have allowed researchers to verify the commonly used stellar structure model – which describes the internal structure of a star in detail – and make detailed predictions about the brightness, the colour and its future evolution.
Scientists know that old stars have few...
