| « The chemistry of planet formation in the era of ALMA » |
|
Catherine Walsh |
| The chemical composition of planets and comets is inherited from the protoplanetary disk that forms around new stars. Precursors to larger, biologically-relevant molecules are detected in many astrophysical environments, but determining the presence and properties of these feedstock molecules during the process of planet formation requires high angular resolution and sensitivity observations: this is only possible now in the era of ALMA (the Atacama Large Millimeter/submillimeter Array). I will present state-of-the-art observations of organic (carbon-bearing) molecules in protoplanetary disks observed with ALMA, some of which come from the MAPS Large Program (Molecules with ALMA on Planet-forming Scales: http://alma-maps.info), and some of which is from our ongoing observing campaigns searching for large and complex molecules in protoplanetary disks. I will discuss how the data reveal the composition of the planet-building environment, and I will compare these data with what we know from the outcome of planet formation in our own Solar System. |
