Astronomers Solve the Case of Missing Carbon Monoxide in Protoplanetary Disks

Astronomers frequently observe carbon monoxide in planetary nurseries. The compound is ultrabright and extremely common in protoplanetary disks—regions of dust and gas where planets form around young stars—making it a prime target for scientists.

But for the last decade or so, something hasn’t been adding up when it comes to carbon monoxide observations, says Diana Powell, a NASA Hubble Fellow at the Center for Astrophysics, Harvard & Smithsonian. A huge chunk of carbon monoxide is missing in all observations of disks, if astronomers’ current predictions of its abundance are correct.

Now, a new model—validated by observations with ALMA—has solved the mystery: carbon monoxide has been hiding in ice format...
