Abstract
It is hard to see a plane cruising at 10 km during daytime, as the plane is tiny and faint on the sky. But, if we can see the contrail tailed behind the plane, we know where the plane is. In addition, by studying the contrail, we learn something about the plane, like where it has been and its speed. Now, astronomers are applying the same technique to study how planets form, by detecting and charactering the structures baby planets produce in their birth cradles — protoplanetary disks. This is a new field largely driven by discoveries made by some of the largest and most advanced telescopes ever built. I will introduce the current status of the field, and highlight some of the latest developments.
