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 clear, however, that classical model photospheres are inadequate to describe the nature of the outer atmospheres. The notion of large optically thick molecular spheres around the stars (MOLspheres) has been invoked in order to explain spectro-interferometric observations and low-and high-resolution… Expand
Infrared spectral properties of M giants
We observed a sample of 20 M giants with the Infrared Spectrograph on the Spitzer Space Telescope. Most show absorption structure at 6.6-6.8 um which we identify as water vapor, and in some cases,Expand
The inner two degrees of the Milky Way. Evidence of a chemical difference between the Galactic Center and the surrounding inner bulge stellar populations
Although there have been numerous studies of chemical abundances in the Galactic bulge, the central two degrees have been relatively unexplored due to the heavy and variable interstellar extinction,Expand
Science cases for a visible interferometer
High spatial resolution is the key for the understanding various astrophysical phenomena. But even with the future E-ELT, single dish instruments are limited to a spatial resolution of about 4 mas inExpand
SOFIA-EXES Mid-IR Observations of [Fe II] Emission from the Extended Atmosphere of Betelgeuse
We present a NASA-DLR SOFIA-Echelon Cross Echelle Spectrograph (EXES) and NASA Infrared Telescope Facility-Texas Echelon Cross Echelle Spectrograph (TEXES) mid-IR R ≃ 50,000 spectral study ofExpand
Accurate abundance analysis of late-type stars: advances in atomic physics
The measurement of stellar properties such as chemical compositions, masses and ages, through stellar spectra, is a fundamental problem in astrophysics. Progress in the understanding, calculation andExpand
The MOLspheres of Mira Variables
Time series of near-IR spectra are used to explore the cool molecular region between the photosphere and expanding circumstellar shell in large amplitude (Mira) AGB variables. The ∼1000 K MiraExpand
ExoMol molecular line lists XXX: a complete high-accuracy line list for water
A new line list for H$_2$$^{16}$O is presented. This line list, which is called POKAZATEL, includes transitions between rotation-vibrational energy levels up to 41000 cm$^{-1}$ in energy and is theExpand


Infrared Spectra and Visibilities as Probes of the Outer Atmospheres of Red Supergiant Stars
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 theExpand
Water vapor on supergiants : The 12 μm texes spectra of μ cephei
Several recent papers have argued for warm, semidetached, molecular layers surrounding red giant and supergiant stars, a concept known as a MOLsphere. Spectroscopic and interferometric analyses haveExpand
Spatially resolving the outer atmosphere of the M giant BK Virginis in the CO first overtone lines with VLTI/AMBER
Context. The mass-loss mechanism in normal K–M giant stars with small variability amplitudes is not yet understood, although the majority among red giant stars are precisely of this type. Aims. WeExpand
Water in K and M giant stars unveiled by ISO
Based on the spectra obtained with Infrared Space Observatory, ISO, we detected the 6.3m bands of water in the late K giant Aldebaran ( Tau) and several early M giant stars (between M0 and M3.5),Expand
Structure of the outer layers of cool standard stars
Context. Among late-type red giants, an interesting change occurs in the structure of the outer atmospheric layers as one moves to later spectral types in the Hertzsprung-Russell diagram: aExpand
