One of the best places to study stars is inside "open clusters," which are groups of stars that formed together from the same material and are bound together through gravity. Open clusters act as ...
Variable stars could offer important hints into aspects of stellar structure and evolution. They could also help us better understand the distance scale of the universe. In particular, the so-called ...
Astronomers using the Swiss 1.2-metre Euler telescope at ESO’s La Silla Observatory in Chile have found a new type of variable star. The discovery was based on the detection of very tiny changes in ...
