Dust in AGB stars: transparent or opaque?
Sara Bladh, Susanne Höfner, Bernhard Aringer
It is commonly believed that winds of cool giants in their late evolutionary stages are driven by radiative pressure on dust grains, but the actual grain species responsible for dr…

Starlight and Sandstorms: Mass Loss Mechanisms on the AGB
Susanne Höfner
There are strong observational indications that the dense slow winds of cool luminous AGB stars are driven by radiative pressure on dust grains which form in the extended atmospher…

Relaxing the Small Particle Approximation for Dust-grain opacities in Carbon-star Wind Models
Lars Mattsson, Susanne Höfner
We have computed wind models with time-dependent dust formation and grain-size dependent opacities, where (1) the problem is simplified by assuming a fixed dust-grain size, and whe…
