An extensive grid of DARWIN models for M-type AGB stars II. Effects of pulsation periods on wind properties
Emelie Siderud, Kjell Eriksson, Susanne Höfner +1
Mass loss from asymptotic giant branch (AGB) stars is the result of a complex interplay between pulsation, atmospheric dynamics, dust formation, and radiative acceleration. Pulsati…

Multi-mode Pulsations in AGB Stars: Insights from 3D RHD CO5BOLD Simulations
Arief Ahmad, Bernd Freytag, Susanne Höfner
Stars on the AGB can exhibit acoustic pulsation modes of different radial orders, along with non-radial modes. These pulsations are essential to the mass-loss process and influence…

Retrieving stellar parameters and dynamics of AGB stars with Gaia parallax measurements and CO5BOLD RHD simulations
E. Béguin, A. Chiavassa, A. Ahmad +2
Context. The complex dynamics of asymptotic giant branch (AGB) stars and the resulting stellar winds have a significant impact on the measurements of stellar parameters and amplify…
