Direct imaging of mass transfer and circumcompanion structures in π1 Gru with VLTI/MATISSE

Aims. We investigate how the presence of a binary companion appears to affect dust and molecule formation in the circumstellar environment of a star on the asymptotic giant branch (AGB). Methods.L- and N-band observations obtained over the course of one month with the multi aperTure mid-infrared spe...
