In new research, found that there was a good correlation between the flicker of a star and its surface gravity.
Astronomers have found a stormy dark spot on a small star.
A contact binary star occurs when two stars are close enough that their outer layers are in contact with each other.
Astronomers have developed a new method using “twin stars” to measure stellar distances.
Suppose you wanted to build a star. How would you go about making one?
Why do young stars contain so much lithium? That might seem an odd question, but it’s a question that has nagged astronomers for quite some time.
Astronomers can measure the distance to about a billion stars using the same effect that lets you enjoy a 3D summer blockbuster.
The stars in our galaxy can change orbits over time. Through “close encounters” with other stars, they can find themselves in very different regions of the galaxy than their region of origin. Now new research finds that about a third of stars drift to new orbits in their lifetime.
Brown dwarfs are like the Pluto of stars. New research published in Nature points to a more planetary nature by discovering bright aurora on a brown dwarf.
