Multi-band infrared imaging reveals dusty spiral arcs around the binary B[e] star 3 Puppis
M. Abello, J. Drevon, A. Meilland +24
3 Puppis is the brightest known B[e] star. Recent work classifies this A-type object as a supergiant, yet the impact of its binarity on the circumstellar environment (CE) remains h…
Mid-infrared circumstellar emission of the long-period Cepheid l Carinae resolved with VLTI/MATISSE
V. Hocdé, N. Nardetto, A. Matter +149
The nature of circumstellar envelopes (CSE) around Cepheids is still a matter of debate. The physical origin of their infrared (IR) excess could be either a shell of ionized gas, o…
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…
A thin shell of ionized gas explaining the IR excess of classical Cepheids
V. Hocdé, N. Nardetto, E. Lagadec +12
Despite observational evidences, InfraRed (IR) excess of classical Cepheids are seldom studied and poorly understood, but probably induces systematics on the Period-Luminosity (PL)…
Understanding the dynamical structure of pulsating stars: The Baade-Wesselink projection factor of the delta Scuti stars AI Vel and beta Cas
G. Guiglion, N. Nardetto, P. Mathias +6
Aims. The Baade-Wesselink method of distance determination is based on the oscillations of pulsating stars. The key parameter of this method is the projection factor used to conver…
On the CQE Phase Signature Feature in High-Resolution Spectro-Interferometry of Be Stars
D. M. Faes, A. C. Carciofi, Th. Rivinius +3
We analyse a feature that is detectable at the differential phases of high-resolution spectro-interferometry of Be stars. The origin of this feature (dubbed CQE-PS, Central Quasi E…
