About the Survey

The ARKS programme uses the Atacama Large Millimeter/submillimeter Array (ALMA) to provide the first high-resolution views of a large sample of these adolescent planetary systems, through their debris discs, also known as exoKuiper belts. With a combination of new and archival data, we have analysed a diverse sample of 24 exoKuiper belts. In the initial series of ten papers, we study:

• The radial and vertical structure of the dust belts,
• The density, temperature, and kinematics of molecular gas,
• The relationship between the different dust populations seen in radio and optical light,
• The asymmetries present in the dust belts, and
• The unusual debris disks around HD 121617 (which has a pronounced dust arc and interesting gas kinematics) and HD 131835 (which has two belts that flip in brightness between millimetre and scattered light).
