A central finding of the research showed that surface changes in starspots on XX Trianguli do not follow sun-like magnetic ...

Recently, however, astronomers have been keeping track of starspot activity on a red giant star called XX Trianguli, and the irregular behaviour of its starspots suggests its interior may have ...

Facts about the red giant star and where to find it are explained by Space.com's Chelsea Gohd. [Betelgeuse: The Eventual ...

Astronomers have discovered a new type of red giant star near the centre of the galaxy. A project led by the University of Hertfordshire has spent 10 years studying almost a billion stars in the ...

Infrared images of a red giant star about 30,000 light years away, near the centre of our Milky Way galaxy, that faded away and then reappeared over the course of several years.

In 5 billion years, our Sun–a regular yellow dwarf star–will turn into a red giant and then into an expanding and glowing ring-shaped shell of gas. In the process, it will swallow up Mercury ...

Astronomers have been tracking starspots on a red giant star, XX Trianguli, and their findings reveal unpredictable internal behaviour. Unlike the sun, this distant star’s surface activity doesn ...

around a hundred red giant stars—some of the oldest stars in our galaxy—some of which appear to pre-date the Milky Way's collision with another small galaxy called the Gaia-Enceladus-Sausage.

At this stage, the star becomes a large red giant. Because a red giant is so large, its heat spreads out and the surface temperatures are predominantly cool, but its core remains red-hot.
