Astronomers have discovered that an aging red giant star has a closely orbiting stellar companion, which could be causing havoc to the star's processes. The discovery could help researchers better ...

Astronomers have identified a massive red giant star with a newly detected companion that appears to be stirring up trouble in the system, reshaping gas and dust in ways that could end in a dramatic ...

Their results were published in the journal Astronomy and Astrophysics. Together, the observations and simulations show that dust grains alone cannot explain how winds escape from oxygen-rich red ...

Aging stars can completely destroy their planets. When a star reaches the end of its life on the main sequence, it goes through dramatic changes. And those changes don't just dictate the star's fate; ...

A distant red giant star is rippling with seismic vibrations, and for the first time, a NASA spacecraft has translated those subtle pulses into a kind of cosmic song directed at a hidden black hole ...

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, ...
