The SPHERE infrared survey for exoplanets (SHINE) V. Full sample characterization

V. Squicciarini, S. Desidera, G. Chauvin +109

Unbiased surveys of large stellar samples are the prime means through which the prevalence of exoplanets can be derived, and crucial constraints to planet formation models can be s…

Discovery of a Low-Mass Companion to the Accelerating Star HIP 53005 with Strongly Conflicting Mass Estimates

Taichi Uyama, Thayne Currie, Jerry W. Xuan +22

We present the discovery of a low-mass companion located at 0\farcs{}85 () from the early-type 1.2 Gyr-old star HIP 53005 using direct imagi…

The ALMA survey to Resolve exoKuiper belt Substructures (ARKS) V: Comparison between scattered light and thermal emission

J. Milli, J. Olofsson, M. Bonduelle +33

Debris discs are analogues to our own Kuiper belt around main-sequence stars and are therefore referred to as exoKuiper belts. They have been resolved at high angular resolution at…

JWST/MIRI coronagraphic search for planets in systems with gapped exoKuiper belts and proper motion anomalies

R. Bendahan-West, S. Marino, A. L. Carter +17

Over the past decade, ALMA has uncovered a range of substructures within exoKuiper belts, pointing to a population of undetected planets. With JWST's sensitivity, we now have the o…

JWST/NIRCam observations of HD~92945 debris disk: An asymmetric disk with a gap

C. Lazzoni, R. Bendahan-West, S. Marino +9

We present the first observations of the HD92945 debris disk obtained with JWST, targeting this nearby K0V star located at 21.54 pc from the Sun. High-contrast coronagraphic imagin…

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…
