There is something strange happening with some stars.
There are large structural variations in the inner core of red giants. Astronomers are finding moreglitches than they thought they'd find.
This isn't the first time that glitching in stars has made headlines, but it's the first one that had to do with a star's rotation A new study published in the journal Nature Communications states that the glitch affects more than just a star's behavior.
A specific type of red giant known as "red clumps" all have the same luminosity and can be used as standard candles to determine their distance. They're essential to understanding and figuring out our universe.
It's a good idea to find out why some of them are undergoing some strange changes to their core structures.
The study lead author said that they can use the variations to get more information about the stars and their objects.
There were 24 red giants that showed signs of glitching at some point in their lives. At a large scale, that's seven percent.
The science is not clear as to why these things happen. One of the two prevailing theories suggests that a star's evolution is normal, but most of the time they are not noticed.
Vrard's findings don't seem to support the theory that a physical process leads to intermittent changes in the structure of the core.
Astronomers will be determined to get to the bottom of the mystery, thanks to Vrard's study.
There is a black hole in the sky.
