Asymptotic Giant Branch (AGB) stars represent a late evolutionary stage of low to intermediate-mass stars (approximately 0.8–8 M⊙). After exhausting hydrogen and helium in their cores, these stars ...

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, ...

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, ...

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 ...

Astronomers have identified a rare and extraordinary triple star system in our galaxy using NASA’s Transiting Exoplanet ...

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; ...

Astronomers have long searched for clues that a hidden companion star sits out of view near the red supergiant star Betelgeuse. Now, they’ve uncovered a new piece of evidence: a trail like the wake ...
