Caption: This image shows extended emission, an elliptical ring structure of size about 0.045x0.03 pc as well as two peaks of emission, separated by about 3" (240 AU). One of the two peaks coincides with the position of HD 97300, while the other may be an embedded companion. The data show that the emission in this region is dominated by the infrared emission bands centered at 6.2, 7.7, 8.7, 11.3 and 12.5 µm, with a very small contribution from continuum emission at longer wavelengths.

This observation has been discussed in details in the A&A paper: "A ring of organic molecules around HD 97300".
