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…

A triple star in disarray -- Multi-epoch observations of T Tauri with VLT-SPHERE and LBT-LUCI

M. Kasper, K. K. R. Santhakumari, T. M. Herbst +24

T Tauri remains an enigmatic triple star for which neither the evolutionary state of the stars themselves, nor the geometry of the complex outflow system is completely understood.…

The GRAVITY Young Stellar Object survey IV. The CO overtone emission in 51 Oph at sub-au scales

GRAVITY Collaboration, M. Koutoulaki, R. Garcia Lopez +69

51 Oph is a Herbig Ae/Be star that exhibits strong near-infrared CO ro-vibrational emission at 2.3 micron, most likely originating in the innermost regions of a circumstellar disc.…

A single-armed spiral in the protoplanetary disk around HD34282 ?

J. de Boer, C. Ginski, G. Chauvin +17

During the evolution of protoplanetary disks into planetary systems we expect to detect signatures that trace mechanisms such as planet-disk interaction. Protoplanetary disks displ…

Direct confirmation of the radial-velocity planet Pic c

M. Nowak, S. Lacour, A. -M. Lagrange +90

Methods used to detect giant exoplanets can be broadly divided into two categories: indirect and direct. Indirect methods are more sensitive to planets with a small orbital period,…
