Peering Into Planet Formation: from ALMA and JVLA to the ngVLA
American Astronomical Society Meeting Abstracts #233
In the last five years, ALMA and JVLA have delivered images of the environment surrounding young stars that transformed our understanding of planet formation. A major discovery is that circumstellar dust and pebbles are not smoothly distributed around the star but they instead accumulate in narrow circular rings that are created by the radial motion of solid particles towards local maxima of the gas pressure. These structures are thought to originate from the gravitational interaction between the circumstellar material and giant planets, and might be the place where most of the rocky planets form. In my poster, I will present results from the ALMA ''Disk Substractures at High Angular Resolution Project" and from recent JVLA observations that probe the formation of giant planets as close as 10 au from the central star. I will further discuss how the next generation of long-baseline interferometers (e.g., the next generation VLA) will enable us to extend the study of planet formation in the region where most of the planets are expected to form (<10au) and probe the presence of planets as small as a few Earth masses.
