ISO impact on stellar models and vice versa
L. Decin, C. Waelkens, K. Eriksson +5
We present a detailed spectroscopic study of a sample of bright, mostly cool, stars observed with the Short-Wavelength Spectrometer (SWS) on board the Infrared Space Observatory (I…
ISO-SWS calibration and the accurate modelling of cool-star atmospheres: I. Method
L. Decin, C. Waelkens, K. Eriksson +5
A detailed spectroscopic study of the ISO-SWS data of the red giant Alpha Tau is presented, which enables not only the accurate determination of the stellar parameters of Alpha Tau…
ISO-SWS observations of interstellar solid 13CO2: heated ice and the Galactic 12C/13C abundance ratio
A. C. A. Boogert, P. Ehrenfreund, P. A. Gerakines +7
We present observations of the stretching mode of 13CO2 ice along 13 lines of sight in the Galaxy, using the Short Wavelength Spectrometer on board of the Infrared Space Observator…
Photospheric composition of the carbon-rich 21 micron post-AGB stars IRAS 22223+4327 and IRAS 04296+3429
Leen Decin, Hans Van Winckel, Christoffel Waelkens +1
We present a detailed chemical analysis on the basis of high-resolution, high signal-to-noise optical spectra of two post-AGB objects IRAS 22223+4327 and IRAS 04296+3429. Both disp…
