The Infrared Spectrum of R Doradus

Abstract

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 Spectrometer on board the Infrared Space Observatory. We will also present the entire spectrum of R Dor up to 5 microns based on our model photosphere in order to show which molecules are important for the emergent spectrum.
