A high resolution study of diffuse interstellar bands

  • 2. Institute of Astronomy, Torun (Poland)

Description

High resolution (0.05 A) spectra are used for the determination of the profiles of the diffuse interstellar bands 5780 and 5797 originating in single clouds. It is shown that some of the clouds may contain agents of certain diffuse bands whereas others may not. The profiles of diffuse bands observed in distant stars contain contributions from several clouds, differing in optical properties, which share the Doppler displacements observed in interstellar sodium lines. The Doppler splitting inside the diffuse bands' profiles is, however, efficiently veiled because of the large intrinsic widths of the bands under consideration. (author). 7 figs., 15 res
