Detecting planetary mass companions near the water frost-line using JWST interferometry

Shrishmoy Ray, Sasha Hinkley, Steph Sallum +4

JWST promises to be the most versatile infrared observatory for the next two decades. The Near Infrared and Slitless Spectrograph (NIRISS) instrument, when used in the Aperture Mas…

The high-albedo, low polarization disk around HD 114082 harbouring a Jupiter-sized transiting planet

N. Engler, J. Milli, R. Gratton +36

We present new optical and near-IR images of debris disk around the F-type star HD 114082. We obtained direct imaging observations and analysed the TESS photometric time series dat…

TOI-179: a young system with a transiting compact Neptune-mass planet and a low-mass companion in outer orbit

S. Desidera, M. Damasso, R. Gratton +29

Transiting planets around young stars are key benchmarks for our understanding of planetary systems. One of such candidates was identified around the K dwarf HD 18599 by TESS, labe…

MADYS: the Manifold Age Determination for Young Stars

Vito Squicciarini, Mariangela Bonavita

The unrivalled astrometric and photometric capabilities of the Gaia mission have given new impetus to the study of young stars: both from an environmental perspective, as members o…

Results from The COPAINS Pilot Survey: four new brown dwarfs and a high companion detection rate for accelerating stars

M. Bonavita, C. Fontanive, R. Gratton +6

The last decade of direct imaging (DI) searches for sub-stellar companions has uncovered a widely diverse sample that challenges the current formation models, while highlighting th…

A scaled-up planetary system around a supernova progenitor

V. Squicciarini, R. Gratton, M. Janson +24

Virtually all known exoplanets reside around stars with ; to clarify if the dearth of planets around more massive stars is real, we launched the direct-imaging B-sta…
