Infrared emission from interstellar dust cloud with two embedded sources: IRAS 19181+1349
Mid and far infrared maps of many Galactic star forming regions show multiple peaks in close proximity , implying more than one embedded energy sources. With the aim of understanding such interstellar clouds better, the present study models the case of two embedded sources. A radiative transfer scheme has been developed to deal with an uniform density dust cloud in a cylindrical geometry, which...
متن کاملThe Diffuse Interstellar Bands: A Major Problem in Astronomical Spectroscopy
A critical review of the very long-standing problem of the diffuse interstellar bands is presented with emphasis on spectroscopic aspects of observational, modelling and laboratory-based research. Some research themes and ideas that could be explored theoretically and experimentally are discussed. The article is based on the Journal of Molecular Spectroscopy Review Lecture presented at the 60th...
متن کاملNear-infrared photometry and optical spectroscopy of IRAS sources in the Small Magellanic Cloud
Near-infrared photometry is obtained of 30 IRAS sources in the direction of the Small Magellanic Cloud selected to be possible AGB stars. Low resolution 4000 to 10 000 Å spectroscopy is presented for 10 of them, plus two AGB stars in the LMC. Improved IRAS fluxes are obtained using the gipsy package. Based on the optical spectra and analyses of colour-colour diagrams 9 are confirmed or likely c...
متن کاملComparative Studies of Visible and IRAS Interplanetary Dust Bands
We have examined the diversity and similarity of visible dust bands and infrared dust bands based on data obtained by our ground-based observations (Ishiguro et al. 1999, ApJ 511, 432) and by the Infrared Astronomy Satellite (IRAS). It is found that the latitude profile of visible dust bands at the solar elongation, A — A® = 89°, is similar to that of infrared dust bands, except for the appeara...
متن کاملLaboratory Optical Spectroscopy of the Phenoxy Radical as a Candidate for Diffuse Interstellar Bands
The gas-phase optical absorption spectrum of the B A X B 2 2 2 1 ̃ ̃ ¬ transition of a phenoxy radical (C6H5O), which is a candidate molecule of diffuse interstellar bands (DIBs), was observed in the discharge of anisole using a cavity ring-down spectrometer. The spectrum comprised four peaks having broad and asymmetric profiles, which were regarded as a vibrational progression of ∼500 cm. The p...
