In the past few years, ALMA unveiled a variety of substructures (rings, spirals, crescents) in the continuum emission of most protoplanetary disks imaged at high spatial resolution…
Benchmarking pre-main sequence stellar evolutionary tracks using disk-based dynamical stellar masses
Luigi Zallio, Miguel Vioque, Sean M. Andrews +14
Stellar masses are a fundamental property to understand models of pre-main sequence evolution, but their values derived from Hertzsprung-Russell (HR) diagrams are strongly model de…
The 12CO Gas Structures of Protoplanetary Disks in the Upper Scorpius Region
Luigi Zallio, Giovanni P. Rosotti, Miguel Vioque +13
We present measurements of key protoplanetary disk properties inferred from parametric models of ALMA 12CO spectral line visibilities. We derive gas-disk radii, integrated fluxes,…
An Introduction to Dust Evolution and Vertical Transport in Protoplanetary Disks

Asymmetric Signatures of Warps in Edge-on Disks
Carolin N. Kimmig, Marion Villenave
Protoplanetary disks observed edge-on commonly show asymmetries that can be caused by shadows cast from a warp. With the growing amount of these observations, methods to constrain…
Gravito-turbulent bi-fluid protoplanetary discs: 1. An analytical perspective to stratification
S. Rendon Restrepo, U. Ziegler, M. Villenave +1
Context. In Class 0/I and the outskirts of Class II circumstellar discs, the self-gravity of gas significantly affects the disc's vertical hydrostatic equilibrium. The contribution…
