# Astronomers Intrigued by Certain Stars That Are “Glitching”

## Stellar Coding

Something strange is happening with certain stars: they're "glitching."

Stellar "glitches," as they're called, are large structural variations that occur in the inner cores of red giants. And astronomers, after taking a deeper look, are finding more of these "glitches" than they ever expected.

This is not the first time that [glitching in stars](<https://futurism.com/the-byte/neutron-star-just-glitched>) has made headlines, but those instances had to do with a star's rotation. The glitches here, according to the [new study](<https://www.nature.com/articles/s41467-022-34986-z>) published in the journal *Nature Communications*, affect much more, including a star's oscillations and the behavior of passing sound waves (yes, it's counterintuitive, but scientists do [refer to "sound" in space](<https://exoplanets.nasa.gov/news/1516/symphony-of-stars-the-science-of-stellar-sound-waves/>).)

A specific type of red giant known as "red clumps" all possess the same luminosity, allowing astronomers to use them as what's known as "standard candles" to determine their distance, and by extension that of their surrounding galaxies, kind of like galactic waypoints. Simply put, they're essential to understanding and charting our universe.

So when it turns out that some of them are undergoing some baffling variations to their core structures, it's a good idea to find out why — since so much of cosmology relies on understanding their behavior.

"By analyzing these variations, we can use them to obtain not only the global parameters of the star, but also information on the precise structure of those objects," said study lead author Mathieu Vrard in a [press release](<https://news.osu.edu/astronomers-discover-clues-about-stellar-glitching/>).

## Gamebreaking Bug

From a sample of 359 red giants, 24 were found to have exhibited signs of glitching at some point in their lifetime. That's around seven percent — an absolutely massive proportion at a cosmic scale.

As to why these glitches occur, the science is unclear. One of two prevailing theories suggests that glitches are a normal part of a star's evolution, but most that occur are too insignificant to notice.

But Vrard's findings don't seem to support this theory, and suggest that glitches are "temporarily smoothed out by some unknown physical process that leads to intermittent changes in the structure of the core," the study reads.

It's a mystery that astronomers will be determined to get to the bottom of — and Vrard's study lays down the gauntlet.

## Author
At Futurism, my work has often centered on bringing a sense of clarity and insight to complex topics ranging from the regulation of emerging technologies to the esoteric ideologies of Silicon Valley executives, while striving not to lose the poetic sense of awe inspired by often-obscure fields like astrophysics and quantum computing. I broke the story of CNET using AI to produce articles that turned out to be riddled with factual errors and plagiarism — a dam-breaking inflection point, as I've reported, that's inspired copycats and endless discourse while beguiling stakeholders ranging from tech giants to purveyors of spam around the web. My work at Futurism has been cited by publications including CBS News, the Los Angeles Times, Vice, Gizmodo, Engadget, the Verge, and Vanity Fair. I grew up in locales ranging from India to China, and now live in the exotic suburbs of Virginia. In my free time, I'm an avid reader of weird sci-fi literature, an aficionado of East Asian cinema, and, regrettably, a relapsed gamer. Allegedly, I’m working on a debut novel, currently untitled.
