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...

Description
Summary: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).
