CrH and FeH bands in atmospheres of the ultracool objects
Absorption CrH and FeH bands are of importance for study of atmospheres of ultracool dwarfs (Teff < 2200 K). Results from calculations of synthetic spectra of these objects using the new theoretical CrH and FeH opacities obtained by Burrows et al. [2] and Dulick et al. [3], respectively, are disc...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | Absorption CrH and FeH bands are of importance for study of atmospheres of ultracool dwarfs (Teff < 2200 K). Results from calculations of synthetic spectra of these objects using the new theoretical CrH and FeH opacities obtained by Burrows et al. [2] and Dulick et al. [3], respectively, are discussed. Comparison of the CrH and FeH spectra computed with the JOLA approximation and Burrows data is carried out. Dependencies of SEDs of ulracool dwarfs on temperature, gravity, dust opacity are discussed. We compare our synthetic SEDs with an observed spectrum of Kelu-1 (L2). |
