Multi-epoch scattered-light analysis of HD 135344B: new evidence for a spiral-driving protoplanet

J. Latour, V. Christiaens, O. Absil +17

The HD 135344B (SAO 206462) disk exhibits strong signposts of planet formation. ALMA images in the sub-mm revealed a gap-crossing dust filament whose position coincides with a twis…

Two inner dust clumps in PDS 70. A third protoplanet traced by trojan material or a substructured inner disk?

O. Balsalobre-Ruza, V. Christiaens, N. Huélamo +18

The PDS 70 cavity hosts two confirmed directly imaged protoplanets and a third inner planet candidate at 13au, labeled PDS 70 d. Despite its Keplerian motion, its unusually blue sp…

Keplerian motion of a compact source orbiting the inner disc of PDS 70: a third protoplanet in resonance with b and c?

Iain Hammond, Valentin Christiaens, Daniel J. Price +10

The disc around PDS 70 hosts two directly imaged protoplanets in a gap. Previous VLT/SPHERE and recent James Webb Space Telescope/NIRCam observations have hinted at the presence of…

Dust populations from 30 to 1000 au in the debris disk of HD 120326

C. Desgrange, J. Milli, G. Chauvin +15

Context. To date, more than a hundred debris disks have been spatially resolved. Among them, the young system HD 120326 stands out, displaying different disk substructures on both…

Combining reference-star and angular differential imaging for high-contrast imaging of extended sources

Sandrine Juillard, Valentin Christiaens, Olivier Absil +2

High-contrast imaging (HCI) is a technique designed to observe faint signals near bright sources, such as exoplanets and circumstellar disks. The primary challenge in revealing the…
