The young protostellar disk in IRAS16293-2422 B is hot and shows signatures of gravitational instability

Autor: Bo Zhao, Duncan Forgan, Hauyu Baobab Liu, Paola Caselli, John D. Ilee, Joaquin Zamponi, María José Maureira

Deeply embedded protostars are actively fed from their surrounding envelopes through their protostellar disk. The physical structure of such early disks might be different from that of more evolved sources due to the active accretion. We present 1.3

The SHINE project is a 500-star survey performed with SPHERE on the VLT for the purpose of directly detecting new substellar companions and understanding their formation and early evolution. Here we present an initial statistical analysis for a subsa

Classifying and modelling spiral structures in hydrodynamic simulations of astrophysical discs

We demonstrate numerical techniques for automatic identification of individual spiral arms in hydrodynamic simulations of astrophysical discs. Building on our earlier work, which used tensor classification to identify regions that were "spiral-like",
