The stars are making “music” that could explain where the cosmos come from, scientists say

The “music” of the stars could help to explain how galaxies are formed, according to scientists.

The stars we see in the night sky are undergoing continuous “Starquakes” who mean that their brightness always floats.

These fluctuations can be transformed into frequencies, as those of music say, scientists. Frequencies in turn can help us understand how many years and huge is a star, as well as other characteristics.

The researchers claim to be able to listen to changes in those frequencies, such as the tone of a piece of music, to understand the history and origins of the stars.

“Starquakes occur in some stars, leading to a continuous lighting and darkening cycle. By carefully observing these small fluctuations in brightness, we can listen to the musical rhythm of a star,” said Claudia Reyes, from Australian National University.

“These fluctuations are like musical notes, similar to the vibrations of a rope or the hum of a drum, which can be translated into frequencies. Each frequency tells us more about the size of the star, the chemical composition and the internal structure.”

In the study, the researchers examined a group of 27 stars 2,700 light years away, examining the “sounds” they made. They were chosen because they are all brothers: they were born in the same gas cloud, four billion years ago, with similar but different masses.

This allows scientists to compare them more easily. Looking at their masses, they can see how quickly they have evolved.

But research could help scientists better understand the stars very close to home, like our sun. He was born in a similar cluster, and therefore the results will help to explain what could happen as he ages.

The results are reported in a new study, “acoustic methods in the stars of the M67 cluster traces by deepening the convective envelopes”, published in the magazine Nature.
