In the light of the recent results of the stellar interferometry, we examine the nature of the extra molecular layer outside the photosphere of red supergiant stars, so far studied mostly with the use of the infrared spectra. Although the visibility data are more direct probes of the spatial structure of the outer atmosphere, it is essential that they are analyzed in combination with the spectral data. In the case of the M2 supergiant μ Cephei, several sets of data, both spectra and… 

Fundamental properties and atmospheric structure of the red supergiant VY Canis Majoris based on VLTI/AMBER spectro-interferometry

Aims. We investigate the atmospheric structure and fundamental properties of the red supergiant VY CMa. Methods. We obtained near-infrared spectro-interferometric observations of VY CMa with spectral

The molecular and dusty composition of Betelgeuse's inner circumstellar environment

Context. The study of the atmosphere of red supergiant stars in general and of Betelgeuse (α Orionis) in particular is of prime importance to understand dust formation and how mass is lost to the

Systematic trend of water vapour absorption in red giant atmospheres revealed by high resolution TEXES 12 mu m spectra

Context. The structures of the outer atmospheres of red giants are very complex. Recent interpretations of a range of different observations have led to contradictory views of these regions. It is

Spatially resolving the atmospheric dynamics over the surface of red supergiants with the Very Large Telescope Interferometer

The mass-loss mechanism in red supergiants is a long-stand-ing problem. The milliarcsecond angular resolution achieved by infrared long-baseline interferometry provides us with the only way to

The K giant star Arcturus: the hybrid nature of its infrared spectrum

We study infrared spectrum of Arcturus to clarify the nature of the cool component of its atmosphere, referred to as the CO-mosphere, with the use of the IR spectral atlas by Hinkle et al.(1995). The


We present an interferometric study of the continuum surface of the red supergiant star Betelgeuse at 11.15 μm wavelength, using data obtained with the Berkeley Infrared Spatial Interferometer each

Modelling the spectral energy distribution of the red giant in RS Ophiuchi: evidence for irradiation

We present an analysis of optical and infrared spectra of the recurrent nova RS Oph obtained during between 2006 and 2009. The best fit to the optical spectrum for 2006 September 28 gives Teff = 3900

High spectral resolution spectroscopy of the SiO fundamental lines in red giants and red supergiants with VLT/VISIR

Context. The mass-loss mechanism in red giants and red supergiants is not yet understood well. The SiO fundamental lines near 8 μm are potentially useful for probing the outer atmosphere, which is

A CO-multilayer outer atmosphere for eight evolved stars revealed with VLTI/AMBER

We determine the physical parameters of the outer atmosphere of a sample of eight evolved stars, including the red supergiant α Scorpii, the red giant branch stars α Bootis and γ Crucis, the K

The atmospheric structure and fundamental parameters of the red supergiants AH Scorpii, UY Scuti, and KW Sagittarii

Aims. We present the atmospheric structure and the fundamental properties of the red supergiants (RSGs) AH Sco, UY Sct, and KW Sgr based on VLTI/AMBER observations. Methods. We carried out



Study of molecular layers in the atmosphere of the supergiant star $\mu$ Cep by interferometry in the K band

Infrared interferometry of supergiant and Mira stars has recently been reinterpreted as revealing the presence of deep molecular layers. Empirical models for a photosphere surrounded by a simple

Unveiling Mira stars behind the molecules - Confirmation of the molecular layer model with narrow band near-infrared interferometry

We have observed Mira stars with the FLUOR beamcombiner on the IOTA interferometer in narrow bands around $2.2\,\mu$m wavelength. We find systematically larger diameters in bands contaminated by

Radio Photospheres of Long-Period Variable Stars

We report the detection of centimeter-wavelength emission from a sample of nearby long-period (Mira and semiregular) variables using the VLA. Six of the eight stars in the sample were detected. We
