Spectral energy distribution of late stage stars
Abstract
This paper presents a catalog of the energy distribution in the spectra of 263 stars in the wavelength range from 0.4 to 100 μm, which are at late stages of evolution and have been observed by the ISO space observatory. For each object in the catalog, estimates of the observed bolometric fluxes were derived from smoothed energy distribution curves. The catalog is available at https://infra.sai.msu.ru/sai\lss\sed both as a table and in machine-readable format. It is shown that for the specified sample of objects their ISO SWS spectra in the range 2.4-45 μm only 60% of cases correspond to the general shape of the continuum, and can be used without recalibration. A selection of carbon stars, accessible for the infrared observations from the MSU observatories has been made. For some of them the first brightness estimates in the K, L, and M bands were obtained with the new IR camera of the 2.5-m telescope of CMO.
