Protoplanetary Disks and Planets in Taurus
An international team lead by Feng Long (Peking University) and Paola Pinilla (Steward/University of Arizona), have obtained for the first time an unbiased ALMA survey of 32 protoplanetary disks in the Taurus star forming region, which spans a wide range of properties (e.g., millimeter brightness). In this sample, about 40% of the disks show concentric rings and gaps around young stars, confirming the commonality of these features. These rings and gaps give indirect evidence of planets being formed in their nascent environment. Interestingly, the morphology of these structures suggests that embedded super-Earths and Neptunes are the most likely possibility to explain these rings/gaps, in line with the most common type of planets discovered so far.
