Exploring wind-driving dust species in cool luminous giants II. Constraints from photometry of M-type AGB stars
Sara Bladh, Susanne Höfner, Walter Nowotny +1
The heavy mass loss observed in evolved asymptotic giant branch (AGB) stars is usually attributed to a two-stage process: atmospheric levitation by pulsation-induced shock waves, f…

The wind of the M-type AGB star RT Virginis probed by VLTI/MIDI
Stéphane Sacuto, Sofia Ramstedt, Susanne Höfner +6
We study the circumstellar environment of the M-type AGB star RT Vir using mid-infrared high spatial resolution observations from the ESO-VLTI focal instrument MIDI. The aim of thi…
