HD97300 and its elliptical ring structure
The young central star HD 97300 belongs to a type of stars known to be brighter than average when observed at infrared wavelengths, an outstanding feature that astronomers have been studying with a programme of infrared observations with ISO. The discovery of the giant ring of organic matter is an unexpected result of this campaign. Of all stars targeted for the programme only HD 97300 shows a ring of organic matter, although this fact doesn't necessarily prove the other stars not to have it.
