The recent discovery of thousands of protoplanetary disks and exoplanets
has revealed that planet formation is a very efficient process in
nature. There have been several theories to describe the many steps
along this process, but it remains difficult to discover planets
surrounding young stars. Thanks to its unprecedented angular resolution
and sensitivity at radio wavelengths where the emission from the
circumstellar material is optically thin, the future ngVLA telescope has
the potential to transform our understanding of planet formation. In
this presentation I will highlight the unprecedented imaging
capabilities of the ngVLA using theoretical models of protoplanetary
disks with varying planet and stellar masses. These theoretical models
showcase the temporal evolution of the separation of gas and dust that
in turn forms gaps and rings within the protoplanetary disk. These
images will help shed light on how planets interact with disks and young
stars, as well as on the properties of forming exoplanetary systems. Our
findings suggest that the ngVLA would be capable of detecting the
signatures in the disk of terrestrial planets at few astronomical units
from the host star.
