Together, the observations and simulations show that dust grains alone cannot explain how winds escape from oxygen-rich red giant stars like R Doradus. At this late stage of stellar life, stars ...

The star, called DFK 52, is a member of a cluster of similar red supergiants, but it's losing mass at an extreme rate never seen before. When you purchase through links on our site, we may earn an ...

Spotting celestial objects around asymptotic giant branch (AGB) stars has not been an easy task. These huge, luminous stars often hide things that get too close to them. But for the first time, ...

Scientists observing the red giant star R Doradus have found that starlight isn’t strong enough to drive its stellar winds, overturning a long-standing theory. The dust grains around the star are ...

Astronomers have finally cracked a decades-old mystery about red giant stars—how material from their deep interiors makes its way to the surface. Using cutting-edge supercomputer simulations, ...

Just a few hundred light years from Earth, a swollen red giant is quietly forcing astronomers to rethink how stars seed the galaxy with the raw materials for planets and life. New observations of the ...
