Sean M. Andrews,Jane Huang,Laura M. Pérez,Andrea Isella,Cornelis P. Dullemond,Nicolás T. Kurtovic,Viviana V. Guzmán,John M. Carpenter,David J. Wilner,Shangjia Zhang,Zhaohuan Zhu,Tilman Birnstiel,Xue-Ning Bai,Myriam Benisty,Myriam Benisty,A. Meredith Hughes,Karin I. Öberg,Luca Ricci +17 more
TL;DR: The Disk Substructures at High Angular Resolution Project (DSHARP) as mentioned in this paper was the first large-scale project to find and characterize substructures in the spatial distributions of solid particles for a sample of 20 nearby protoplanetary disks, using very high resolution (similar to 0'' 035 or 5 au, FWHM) observations of their 240 GHz (1.25 mm) continuum emission.

The Disk Substructures at High Angular Resolution Project (DSHARP). II. Characteristics of Annular Substructures
Jane Huang,Sean M. Andrews,Cornelis P. Dullemond,Andrea Isella,Laura M. Pérez,Viviana V. Guzmán,Karin I. Öberg,Zhaohuan Zhu,Shangjia Zhang,Xue-Ning Bai,Myriam Benisty,Myriam Benisty,Tilman Birnstiel,John M. Carpenter,A. Meredith Hughes,Luca Ricci,E. Weaver,David J. Wilner +17 more
TL;DR: In this article, the authors present a systematic analysis of annular substructures in the 18 single-disk systems targeted in this survey, and find that annular structures can occur at virtually any radius where millimeter continuum emission is detected and range in widths from a few astronomical units to tens of astronomical units.

The Disk Substructures at High Angular Resolution Project (DSHARP). VII. The Planet–Disk Interactions Interpretation
Shangjia Zhang,Zhaohuan Zhu,Jane Huang,Viviana V. Guzmán,Sean M. Andrews,Tilman Birnstiel,Cornelis P. Dullemond,John M. Carpenter,Andrea Isella,Laura M. Pérez,Myriam Benisty,Myriam Benisty,David J. Wilner,Clément Baruteau,Xue-Ning Bai,Luca Ricci +15 more
TL;DR: In this paper, a grid of 2D hydrodynamical simulations, including both gas and dust components, is carried out to explore the properties of planets that may be responsible for these substructures.
Journal ArticleDOI
The Disk Substructures at High Angular Resolution Project (DSHARP). VI. Dust Trapping in Thin-ringed Protoplanetary Disks
Cornelis P. Dullemond,Tilman Birnstiel,Jane Huang,Nicolás T. Kurtovic,Sean M. Andrews,Viviana V. Guzmán,Laura M. Pérez,Andrea Isella,Zhaohuan Zhu,Myriam Benisty,Myriam Benisty,David J. Wilner,Xue-Ning Bai,John M. Carpenter,Shangjia Zhang,Luca Ricci +15 more
TL;DR: In this article, the authors test the hypothesis that these dust rings are caused by dust trapping in radial pressure bumps, and if confirmed, put constraints on the physics of the dust trapping mechanism.
Journal ArticleDOI
The comet-like composition of a protoplanetary disk as revealed by complex cyanides
Karin I. Öberg,Viviana V. Guzmán,Kenji Furuya,Chunhua Qi,Yuri Aikawa,Sean M. Andrews,Ryan A. Loomis,David J. Wilner +7 more
TL;DR: It is found that the abundance ratios of these nitrogen-bearing organics in the gas phase are similar to those in comets, which implies that complex organics accompany simpler volatiles in protoplanetary disks, and that the rich organic chemistry of the authors' solar nebula was not unique.
