Radiative hydrodynamics simulations of red supergiant stars. III. Spectro-photocentric variability, photometric variability, and consequences on Gaia measurements

A. Chiavassa, E. Pasquato, A. Jorissen +8

Context. It has been shown that convection in red supergiant stars gives rise to large granules causing surface inhomogeneities together with shock waves in the photosphere. The re…

An investigation of the close environment of beta Cep with the VEGA/CHARA interferometer

N. Nardetto, D. Mourard, I. Tallon-Bosc +22

High-precision interferometric measurements of pulsating stars help to characterize their close environment. In 1974, a close companion was discovered around the pulsating star bet…

Fast ray-tracing algorithm for circumstellar structures (FRACS). II. Disc parameters of the B[e] supergiant CPD-57° 2874 from VLTI/MIDI data

Armando Domiciano De Souza, Philippe Bendjoya, Gilles Niccolini +6

B[e] supergiants are luminous, massive post-main sequence stars exhibiting non-spherical winds, forbidden lines, and hot dust in a disc-like structure. The physical properties of t…

Time, spatial, and spectral resolution of the Halpha line-formation region of Deneb and Rigel with the VEGA/CHARA interferometer

Olivier Chesneau, Luc Dessart, D. Mourard +22

BA-type supergiants are amongst the most optically-bright stars. They are observable in extragalactic environments, hence potential accurate distance indicators. Emission activity…

The H line forming region of AB Aur spatially resolved at sub-AU with the VEGA/CHARA spectro-interferometer

K. Perraut, M. Benisty, D. Mourard +19

A crucial issue in star formation is to understand the physical mechanism by which mass is accreted onto and ejected by a young star. The visible spectrometer VEGA on the CHARA arr…
