A new dimension in the variability of AGB stars: Convection patterns size changes with pulsation
A new dimension in the variability of AGB stars: Convection patterns size changes with pulsation
Context. Stellar convection plays an important role in atmospheric dynamics, wind formation, and the mass-loss processes in asymptotic giant branch stars. However, a direct characterization of convective surface structures in terms of size, contrast, and lifespan is quite challenging, as spatially resolving these features requires the highest angular resolution. Aims. …
