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…
The asymmetric inner disk of the Herbig Ae star HD 163296 in the eyes of VLTI/MATISSE: evidence for a vortex?
J. Varga, M. Hogerheijde, R. van Boekel +133
Context. The inner few au region of planet-forming disks is a complex environment. High angular resolution observations have a key role in understanding the disk structure and the…
Precise calibration of the dependence of surface brightness-colour relations on colour and class for late-type stars
A. Salsi, N. Nardetto, D. Mourard +9
Surface brightness-colour relations (SBCRs) are used to derive the stellar angular diameters from photometric observations. They have various astrophysical applications, such as th…
Pseudomagnitude Distances: Application to the Pleiades cluster
Alain Chelli, Gilles Duvert
The concept of pseudomagnitude was recently introduced by Chelli et al. (2016), to estimate apparent stellar diameters using a strictly observational methodology. Pseudomagnitudes…
Pseudomagnitudes and Differential Surface Brightness: Application to the apparent diameter of stars
Alain Chelli, Gilles Duvert, Laurent Bourgès +4
The diameter of a star is a major observable that serves to test the validity of stellar structure theories. It is also a difficult observable that is mostly obtained with indirect…
High spectral resolution imaging of the dynamical atmosphere of the red supergiant Antares in the CO first overtone lines with VLTI/AMBER
Keiichi Ohnaka, Karl-Heinz Hofmann, Dieter Schertl +5
We present high spectral resolution aperture-synthesis imaging of the red supergiant Antares (alpha Sco) in individual CO first overtone lines with VLTI/AMBER. The reconstructed im…
