OH/IR stars in the inner Galactic bulge: I. Colour, CO line, and stellar light curve characteristics
H. Olofsson, T. Khouri, S. Muller +11
Stars on the asymptotic giant branch (AGB) play important roles in a number of astronomical contexts. To quantify these roles, it is necessary to establish the mass-loss characteri…
The Infrared Spectrum of R Doradus
Nils Ryde, Kjell Eriksson
Here, we present our modelling (Ryde & Eriksson, 2002 A&A 386, 874) of the 2.6-3.7 micron spectrum of the red semiregular variable R Doradus observed with the Short-Wavelength Spec…
Probing the mass loss history of carbon stars using CO line and dust continuum emission
F. L. Schoeier, N. Ryde, H. Olofsson
An extensive modelling of CO line emission from the circumstellar envelopes around a number of carbon stars is performed. By combining radio observations and infrared observations…
Modelling CO emission from Mira's wind
N. Ryde, F. L. Schoeier
We have modelled the circumstellar envelope of {\it o} Ceti (Mira) using new observational constraints. These are obtained from photospheric light scattered in near-IR vibrational-…
The origin of carbon, investigated by spectral analysis of solar-type stars in the Galactic Disk
B. Gustafsson, T. Karlsson, E. Olsson +2
Abundance analysis of carbon has been performed in a sample of 80 late F and early G type dwarf stars in the metallicity range -1.06 < [Fe/H] < 0.26 using the forbidden [C I] line…
