For centuries, astronomers faced the challenge of classifying objects in space based on their appearance. When observing an object that is orbiting a star at a distance, they would often assume it ...

Advances in supercomputing have made solving a long‐standing astronomical conundrum possible: How can we explain the changes in the chemical composition at the surface of red giant stars as they ...

Figuring out the ages of stars is fundamental to understanding many areas of astronomy—yet, it remains a challenge since stellar ages can't be ascertained through observation alone. So, astronomers at ...

The Sun rotates the fastest at the equator, whereas the rotation rate slows down at higher latitudes and is the slowest as the polar regions. But a nearby Sun-like star V889 Herculis, some 115 light ...
