Resolving core-envelope degeneracies in giant planets and sub-Neptunes: constraining the equivalence in the presence of dilute gradients
Christian Wilkinson, Benjamin Charnay, Stéphane Mazevet +4
The widespread recognition of dilute, "fuzzy" cores in giant planets and massive volatile mantles in sub-Neptunes has made interior modelling a highly degenerate, multi-dimensional…

Coherence differential imaging using gradient-boosted decision trees for the direct detection of exoplanets
Johan Mazoyer, MarÃa J. Mellado-Tenorioa, MarÃa J. Mellado-Tenorio +5
Coronagraphic imaging of exoplanets is limited by residual speckles that mimic planets. Advanced post-processing is essential for current and future instruments on the ground or in…

GPI+SPHERE detection of a 6.1 circumbinary planet around HD 143811
Vito Squicciarini, Johan Mazoyer, Christian Wilkinson +6
Owing to its sensitivity to wide-orbit giant exoplanets, direct imaging is uniquely positioned to shed light on the interplay between protoplanetary disks and stellar hosts. In add…
