ALMA

High-resolution images from the ALMA telescope have revealed a variety of shapes in the dust of planet-forming disks, including rings, spirals, and crescents. While most disks show symmetrical rings, some display asymmetric features like blobs or crescents, which may be linked to vortices or the influence of forming planets. This study focuses on the disk around the star HD 163296, where a crescent-shaped arc was observed in the dust using ALMA data at four different wavelengths. The research...
