    Near-infrared spectro-interferometry of Mira variables and comparisons to 1D dynamic model atmospheres and 3D convection simulations
    (2016) Wittkowski, M; Chiavassa, A; Freytag, B; Scholz, M; Höfner, S; Karovicova, I; Whitelock, P A
    Aims. We aim at comparing spectro-interferometric observations of Mira variable asymptotic giant branch (AGB) stars with the latest 1D dynamic model atmospheres based on self-excited pulsation models (CODEX models) and with 3D dynamic model atmospheres including pulsation and convection (CO5BOLD models) to better understand the processes that extend the molecular atmosphere to radii where dust can form.

    The yellow hypergiant HR 5171 A: Resolving a massive interacting binary in the common envelope phase
    (2014) Chesneau, O; Meilland, A; Chapellier, E; Millour, F; van Genderen, A M; Nazé, Y; Smith, N; Spang, A; Smoker, J V; Dessart, L; Kanaan, S; Bendjoya, Ph; Feast, M W; Groh, J H; Lobel, A; Nardetto, N; Otero, S; Oudmaijer, R D; Tekola, A G; Whitelock, P A; Arcos, C; Curé, M; Vanzi, L
    Context. Only a few stars are caught in the very brief and often crucial stages when they quickly traverse the Hertzsprung-Russell diagram, and none has yet been spatially resolved in the mass transfer phase.
