Sounds Of Stars To Help Scientists Shed More Light On How These Celestial Bodies Function


As we already know, the sound doesn’t travel through the vacuum of the Universe, but the stars emit subsonic sounds produced by the nuclear processes that take place inside them. The sounds of stars can help scientists shed more light on how these celestial bodies function and the astrophysicists just came up with the most accurate simulation of how the stars sound like to unveil their mysteries.

While we can’t hear these sounds directly, telescopes can observe these vibrations as modifications in the light or temperature of the stars’ surfaces. By studying these fluctuations, scientists would be able to shed more light on the inner structures of the stars. And that’s precisely what astrophysicists are working on right now as they simulated the sounds of stars.

“A cello sounds like a cello because of its size and shape. The vibrations of stars also depend on their size and structure,” explained Jacqueline Goldstein from the University of Wisconsin-Madison.

Scientists Simulated the Sounds Of Stars to Learn More About These Celestial Bodies Function

Goldstein, the leading author of the new study, managed to create a software that recreates the sounds of stars from the fluctuations of light and temperatures at stars’ surfaces, which are visible for telescopes. The computer program reproduces the vibrations and simulates the frequencies of various stars.

Stars fuse hydrogen to other heavy elements, and due to that fact, the hot plasma gas reverberates making the stars to flicker. By studying those modifications, scientists can learn more about these celestial bodies’ inner structure and how they function. “Those are the ones that explode and make black holes and neutron stars and all the heavy elements in the universe that form planets and, essentially, new life. We want to understand how they work and how they affect the evolution of the universe. So these really big questions,” Goldstein explained.

The software developed by Goldstein, the so-called GYRE, will soon be updated to take advantage of the data obtained by TESS. Goldstein hoped that the future version of GYRE will reproduce the sounds of stars by hundreds of thousands stronger than now.
