An article published in the journal “Astronomy & Astrophysics” describes a research on U Antliae, a rather exotic red giant star. A team of researchers used the ALMA radio telescope to study the bubble of ejected materials that surrounds U Antliae to better understand the evolution of stars in the last stages of their life cycle. That’s a turbulent period in which they can visibly change their volume and their brightness in relatively short times.
