Chen Xie, Chengyan Xie, Bin B. Ren +8
In the early stages of planetary system formation, young exoplanets gravitationally interact with their surrounding environments and leave observable signatures on protoplanetary d…
Disk Evolution Study Through Imaging of Nearby Young Stars (DESTINYS): PDS 111, an old T Tauri star with a young-looking disk
Annelotte Derkink, Christian Ginski, Paola Pinilla +20
The interplay between T Tauri stars and their circumstellar disks, and how this impacts the onset of planet formation has yet to be established. We studied a seemingly old T Tauri…
PDS 70 unveiled by star-hopping: total intensity, polarimetry and mm-imaging modeled in concert
Z. Wahhaj, M. Benisty, C. Ginski +7
Context. Most ground-based planet search direct imaging campaigns use angular differential imaging, which distorts the signal from extended sources like protoplanetary disks. In th…
The environment around young eruptive stars. SPHERE/IRDIS polarimetric imaging of 7 protostars
A. Zurlo, P. Weber, S. Pérez +11
Eruptive stars are a class of young stellar objects that show an abrupt increase in their luminosity. These burst-like episodes are thought to dominate the stellar accretion proces…
The SPHERE view of the Taurus star-forming region
A. Garufi, C. Ginski, R. G. van Holstein +31
The sample of planet-forming disks observed by high-contrast imaging campaigns over the last decade is mature enough to enable the demographical analysis of individual star-forming…
