Science Enthusist
Astronomers had been arguing over the structure of SiC condensing around red giant stars for a number of years. They compared their absorption spectra from red giant stars to measurements performed in the laboratory on synthetic SiC. There has been much debate over the laboratory measurements and interpretation of the features. Wouldn't it be easier to just look at the SiC under the microscope and see what structure it has. This is what is done in this excellent paper. The measurements are a little more tricky than one would think, but a definitive absolute answer is obtained. Most SiC is cubic and there is a small amount of hexagonal SiC. Further, the two structures observed are the ones that form at the lowest temperatures in the laboratory. Nice work that actually answers a question definitively.
