Modeling the nonaxisymmetric structure in the HD 163296 disk with planet-disk interaction
Peter J. Rodenkirch, Thomas Rometsch, Cornelis P. Dullemond +2
High resolution ALMA observations revealed a variety of rich substructures in numerous protoplanetary disks. These structures consist of rings, gaps and asymmetric features. It is…
A highly non-Keplerian protoplanetary disc: Spiral structure in the gas disc of CQ Tau
Lisa Wölfer, Stefano Facchini, Nicolas T. Kurtovic +9
In the past years, high angular resolution observations have revealed that circumstellar discs appear in a variety of shapes with diverse substructures being ubiquitous. This has g…
The Ophiuchus DIsc Survey Employing ALMA (ODISEA)-III: the evolution of substructures in massive discs at 3-5 au resolution
Lucas A. Cieza, Camilo González-Ruilova, Antonio S. Hales +15
We present 1.3 mm continuum ALMA long-baseline observations at 3-5 au resolution of 10 of the brightest discs from the Ophiuchus DIsc Survey Employing ALMA (ODISEA) project. We ide…
A medium-resolution spectrum of the exoplanet HIP 65426 b
Simon Petrus, Mickaël Bonnefoy, Gaël Chauvin +18
Medium-resolution integral-field spectrographs (IFS) coupled with adaptive-optics such as Keck/OSIRIS, VLT/MUSE, or SINFONI are appearing as a new avenue for enhancing the detectio…
Size and structures of disks around very low mass stars in the Taurus star-forming region
Nicolas T. Kurtovic, Paola Pinilla, Feng Long +7
We aim to estimate if structures, such as cavities, rings, and gaps, are common in disks around VLMS and to test models of structure formation in these disks. We also aim to compar…
A search for companions via direct imaging in the DSHARP planet-forming disks
Sebastián Jorquera, Laura M. Pérez, Gaël Chauvin +10
The "Disk Substructures at High Angular Resolution Project" (DSHARP) has revealed an abundance and ubiquity of rings and gaps over a large sample of young planet-forming disks, whi…
