Optimising reference library selection for reference-star differential imaging of discs with SPHERE/IRDIS
S. Stasevic, J. Milli, J. Mazoyer +2
The direct detection of circumstellar discs through high-contrast imaging provides key insights into the history and dynamics of planetary systems. Pole-on discs, especially faint…

Evidence for a sub-jovian planet in the young TWA7 disk
A. -M. Lagrange, C. Wilkinson, M. Mâlin +26
Planets are thought to form from dust and gas in protoplanetary disks, and debris disks are the remnants of planet formation. Aged a few Myr up to a few Gyr, debris disks have lost…

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…
