Diffuse Interstellar Bands and Temperatures in the Interstellar Clouds.

GNACINSKI P., WESELAK T. and KRELOWSKI J.

Abstract (from CDS):

The diffuse interstellar bands (DIBs) observed in the optical and infrared spectrum of interstellar clouds remain the oldest unsolved problem in spectroscopy. We have analyzed correlations between normalized DIBs equivalent widths (EW's) and temperatures of interstellar H2 and CN molecules. The λ 6284 Å DIB is well correlated with T01 temperature of H2. The correlation may be caused by DIB profile broadening or more effective production of DIB carrier at higher temperatures. The DIBs: l4964 A, λ5797 Å and λ6614 Å are anti-correlated with T02 temperature of H2. The anti-correlation may be attributed to destruction of DIBs carriers in high-UV radiation fields.
