Context. The growth of dust grains from sub-μm to mm and cm sizes is the first step towards
the formation of planetesimals. Theoretical models of grain growth predict that dust …

New insights into the nature of transition disks from a complete disk survey of the lupus star-forming region

N van der Marel, JP Williams, M Ansdell… - The Astrophysical …, 2018 - iopscience.iop.org
