Astronomers have used a new camera called the HiPERCAM to analyse a type of small, dim star that has proved elusive to standard cameras. The camera has allowed them to make detailed measurements of this cool subdwarf star 1500 light years away, and it’s the first time they’ve been able to confirm the predicted model of this type of star. Ruby Osborn spoke to Dr Steven Parsons from the University of Sheffield about what makes this star so interesting, and how the HiPERCAM has helped them to study it.
