Organic molecules detected in 5 protoplanetary disks | Digital Trends Spanish

Using the ALMA telescope, located in the Atacama desert (northern Chile), a group of astronomers has managed to map 18 organic and inorganic molecules in protoplanetary discs of five young stars.

These would be IM Lup, GM Aur, AS 209, HD 163296 and MWC 480, and the new maps show that the chemical substances of these discs are not located uniformly in each of them, but that each disc is like a ” different soup of planetary ingredients ”.

These results suggest that planet formation occurs in diverse chemical environments and that, as they form, each planet can be exposed to very different molecules depending on their location on the disk.

Planets form in the gas and dust disks, also known as protoplanetary disks, that surround young stars.

The chemical composition of these disks can influence the planets themselves, including how and where planetary formation occurs, the chemical composition of the planets, and whether they have the organic makeup necessary to support life.

This research led to important discoveries, such as the relationship between dust and chemical substructures and the presence of large reserves of organic molecules in the regions of the inner disk of stars.

“With ALMA we were able to see how molecules are distributed in places where exoplanets are forming,” says Karin Öberg, astronomer at the Center for Astrophysics | Harvard and Smithsonian.

“One of the really exciting things we saw is that the planet-forming disks around these five young stars are factories of a special class of organic molecules, called nitriles, that are implicated in the origins of life here on Earth.” .
