NGC 6072 is a planetary nebulae in the southern constellation of Scorpius. It has a dynamical age of 104 years. Its circumstellar envelope is likely to be rich in carbon as it has very strong CN ( cyanide) spectral lines. CN spectral lines are generally not detected in oxygen rich AGB ( asymptotic giant branch) circumstellar envelopes. NGC 6072 also shows H2 ( hydrogen) emission and intense CO ( carbon monoxide) emission which has been mapped displaying bipolarity and some gas at high velocity. The evolution of this planetary nebulae is likely to be dominated by photodissociation and ion/ radical molecular reactions. Shock chemistry is also likely to be important.
An analysis of Gaia data suggests that the central star is a binary system. [5]
