[93.09] Synthesis of the Infrared Spectra of Stars

C.C. Yost, R.O. Gray (Appalachian State Univ.)

Infrared spectroscopy is an important tool for the study of stars, especially those whose light suffers significant extinction due to the presence of interstellar or circumstellar dust. Within the last few years a number of atlases of stellar spectra in the infrared H, K and J-bands have been published. It is of interest to devise methods to obtain astrophysical information from such spectra. We have compiled a spectral line list from 1 - 4\mu using a number of sources in the astronomical literature. This list contains not only atomic transitions, but also molecular lines for the following diatomic molecules: CH, NH, NO, OH, C2, CN, CO, MgH, SiH and SiO. This line list, which contains nearly 800,000 lines, has been used in conjunction with SPECTRUM, a stellar spectral synthesis code to synthesize a number of representative stellar spectra in the H-band. A comparison of synthetic and observed infrared spectra will be presented in the poster.
