The optical spectrum of the carbon star IRAS 12311−3509 is dominated by the Merrill–Sanford emission bands of SiC2, by absorption and emission in the Swan system of C2, and by resonance emission lines of neutral metals. The infrared energy distri

The biconical Red Rectangle nebula exhibits very strong unidentified infrared (UIR) emission bands, a subset of the optical diffuse interstellar bands (in emission) and extended red emission (ERE). A key question is the extent to which the carriers o

Observations of the Merrill-Sanford bands of SiC2 in the 4750-5050 A spectral region, seen in absorption in some carbon stars and in emission in IRAS 12311-3509, are reported. Vibrational band assignments based on recent laser-based laboratory electr

The elements tantalum, tungsten, and indium have been determined in the Bruderheim meteorite by means of neutron activation analysis. Tantalum was determined by counting the 115-day half-life Ta182 produced by (n, γ) reactions on 99.98 per cent natu
