Queen's 2015 Nobel Prize in PhysicsProf. Sarah Sadavoy won an to study how planets form in disks around young stars. The program aims to examine the youngest disks to understand the conditions under which they become structured, which is key to determining when planets begin to form and the types of planets that will be produced. If these features are sites where planets are born, then the conditions for forming planets arises early in the disk lifetime. This program will use observations of the youngest disks from the Atacama Large Millimeter/submillimeter Array (ALMA), an array of many telescopes that work in tandem to capture small features in disks and identify where and when structures are seen. These data will be combined with simulations and to study how disks first become structured, the connection of these structures to planets, and the initial conditions under which planets and life can arise, including in our own Solar System.
