    Multi-epoch VLTI-PIONIER imaging of the supergiant V766 Cen: Image of the close companion in front of the primary
    (2017) Wittkowski, M; Abellán, F J; Arroyo-Torres, B; Chiavassa, A; Guirado, J C; Marcaide, J M; Alberdi, A; de Wit, W J; Hofmann, K-H; Meilland, A; Millour, F; Mohamed, S; Sanchez-Bermudez, J
    Context. The star V766 Cen (=HR 5171A) was originally classified as a yellow hypergiant but lately found to more likely be a 27−36 M⊙ red supergiant (RSG). Recent observations indicated a close eclipsing companion in the contact or common-envelope phase.

    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.
