Increased shutter speed
proves stellar structure theory.
Star evolution.
The stellar structure model describes the internal structure of a star. Now researchers have validated this model by taking photos of a cool subdwarf star using a high-speed camera, allowing them to predict the star’s future evolution.
Rebessa-Mansergas et al (2019) used HiPERCAM, a camera mounted on the Gran Telescopio Canarias on the island of La Palma. The camera is able to take a photo in five different colours simultaneously every millisecond (compared to every few minutes), allowing the researchers to get precise measurements of the star’s mass and radius – both validating the stellar structure model for the first time and allowing the researchers to forecast the star’s evolution.
