Visible and near-infrared spectro-interferometric analysis of the edge-on Be star Aquarii
E. S. G. de Almeida, A. Meilland, A. Domiciano de Souza +11
We present a detailed visible and near-IR spectro-interferometric analysis of the Be-shell star Aquarii from quasi-contemporaneous CHARA/VEGA and VLTI/AMBER observations. We me…
