Structure of the outer layers of cool standard stars
S. Dehaes, E. Bauwens, L. Decin +6
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 d…
The limb-darkened Arcturus; Imaging with the IOTA/IONIC interferometer
S. Lacour, S. Meimon, E. Thiebaut +14
This paper is an H band interferometric examination of Arcturus, a star frequently used as a spatial and spectral calibrator. Using the IOTA 3 telescope interferometer, we performe…
Amorphous alumina in the extended atmosphere of Alpha Orionis
T. Verhoelst, L. Decin, R. Van Malderen +7
In this paper we study the extended atmosphere of the late-type supergiant Alpha Orionis. Infrared spectroscopy of red supergiants reveals strong molecular bands, some of which do…
Is Arcturus a well-understood K giant? Test of model atmospheres and potential companion detection by near-infrared interferometry
T. Verhoelst, P. J. Bordé, G. Perrin +8
We present near-IR interferometric measurements of the K1.5 giant Arcturus (alpha Bootis), obtained at the IOTA interferometer with the FLUOR instrument, in four narrow filters wit…
