PublicaciónSpinning up the Surface: Evidence for Planetary Engulfment or Unexpected Angular Momentum Transport?
In this paper, we report the potential detection of a nonmonotonic radial rotation profile in a low-mass lower-luminosity giant star. For most low- and...

CharlaStellar Rotation in the Gaia Era: Gyrochronology Under Inspection
Rotation plays an important role in the life of stars and offers a potential diagnostic to infer their ages and that of their planets. This idea is known as...

CharlaSupergiants with an Interesting Past
Exciting things may have happened sometimes to the stars we see in the sky today. For example, Betelgeuse, also known as Alpha-Ori, an M-type red supergiant...
