Science with an ngVLA: Observing the Effects of Chemistry on Exoplanets and Planet Formation

Brett A. McGuire, Edwin Bergin, Geoffrey A. Blake +6

One of the primary mechanisms for inferring the dynamical history of planets in our Solar System and in exoplanetary systems is through observation of elemental ratios (i.e. C/O).…

Science with an ngVLA: Organics in Disk Midplanes with the ngVLA

Karin I. Oberg, L. Ilsedore Cleeves, Ryan Loomis

Planets assemble in the midplanes of protoplanetary disks. The compositions of dust and gas in the disk midplane region determine the compositions of nascent planets, including the…

Constraining Gas-Phase Carbon, Oxygen, and Nitrogen in the IM Lup Protoplanetary Disk

L. Ilsedore Cleeves, Karin I. Oberg, David J. Wilner +4

We present new constraints on gas-phase C, N, and O abundances in the molecular layer of the IM Lup protoplanetary disk. Building on previous physical and chemical modeling of this…

Chemistry During the Gas-rich Stage of Planet Formation

Edwin A. Bergin, L. Ilsedore Cleeves

In this chapter we outline some of the basic understanding of the chemistry that accompanies planet formation. We discuss the basic physical environment which dictates the dominant…

First Detection of the Simplest Organic Acid in a Protoplanetary Disk

Cécile Favre, Davide Fedele, Dmitry Semenov +14

The formation of asteroids, comets and planets occurs in the interior of protoplanetary disks during the early phase of star formation. Consequently, the chemical composition of th…

The Distribution and Excitation of CHCN in a Solar Nebula Analog

Ryan A. Loomis, L. Ilsedore Cleeves, Karin I. Öberg +5

Cometary studies suggest that the organic composition of the early Solar Nebula was rich in complex nitrile species such a CHCN. Recent ALMA detections in protoplanetary disks…
