A glimpse inside δ Scuti stars

A glimpse inside δ Scuti stars

Brightness reveals the music of the spheres Astronomers have decoded the inner pulsations of a class of stars called δ Scuti by precisely tracking how their brightness evolves in time. Stellar pulsations can help researchers to understand the inner structure of a star, “like the standing sound waves responsible for the sounds of musical instruments such as violins and oboes”, write astronomers József Benkő and Margit Paparó. δ Scuti stars have so far been difficult to understand because their pulsations appear to be less regular than those of other types of star. Space scientist and musician Chris Boshuizen used the real data on a δ Scuti called HD 31901 to create this delightful audio and visualization of its pulsations.
