A star that is at least 4.3 light years away How does it make a sound that we can see with our eyes? And how exactly does this sound arise?

of stars Behind the scenes of his surprising performance during a silent concert, Let’s see what Bill Chaplin, professor of astrophysics at the University of Birmingham, said.

First, it is useful to learn what “asteroseismology” is, but those who are tired of the terminology can skip to the second heading.

Asteroseismology offers a unique glimpse into the interior of stars and their evolution. Instead of just looking at the light emitted by stars, scientists know the vibrations they produce They are investigating.

These vibrations, known as stellar oscillations, arise from the interplay of gravity, pressure and nuclear reactions in the star’s core. The essence of asteroseismology is to break these vibrations into pieces. By examining these frequencies and patterns, scientists discover valuable information about a star’s internal dynamics.

We can explain stars and sound through musical instruments.

As Bill Chaplin said a ‘natural music’ of the stars there is. This music lingers, like the sound of a musical instrument. For example, with a wind instrument, vibrations occur after blowing into the instrument and changes in the pressure in the air occur. Sound waves are trapped in the musical instrument.

If we think of the same for a star, we see vibrations in the outer layers of stars like the Sun. sound is captured and a natural sound is created. Even though we can’t hear this sound, we can see it. How works?

Imagine a bowl of water.

If you gently touch the surface of the water, you create a wave that moves outward along the surface. This wave is a sound wave and is caused by pressure changes in the water. The same thing happens with stars.

Think of stars as huge balloons filled with hot, glowing gas. Deep within the star there is enormous pressure in the core. It’s like being at the bottom of a deep ocean, where the water pressure is incredibly intense. This strong pressure in the center of the star, gravity why is this happening.

We can see the sound of stars.

The pressure we are talking about in the star is not constant. It is higher in the core and lower in the outer layers. This pressure gradient is sound waves pass through the star why is this happening.

When the star vibrates, it vibrates slowly because of the sound contained within it. “to breathe”. As this breathing-like situation continues, the gas that makes up the star is compressed, heating up and the star brightening. Eventually it gets cooler and a bit boring outside.

In other words, the brightness of stars changes in a way that turns into sound at frequencies too low for the human ear to hear It’s shaking. We can only see this as blinking and fading.
