ALMA shed light on the chemical composition of a protoplanetary disk

Oct 09, 2020

ALMA shed light on the chemical composition of a protoplanetary disk The team led by Linda Podio, a researcher at INAF, observed a protoplanetary disk of less than 1 million years, which is almost edge-on. The edge-on geometry allowed observing the vertical structure of the disk and to resolve distinct chemical layers. The images obtained thanks to ALMA revealed emission from several molecules. One of these is methanol, a key molecule for the formation of the so-called “complex organic molecules”
