We analyze 5108 AFGKM stars with at least five high-precision radial velocity points, as well
as Gaia and Hipparcos astrometric data, utilizing a novel pipeline developed in previous …

We know little about the outermost exoplanets in planetary systems because our detection
methods are insensitive to moderate-mass planets on wide orbits. However, debris discs …

The exoplanetary system of HR 8799 is one of the rare systems in which multiple planets
have been directly imaged. Its architecture is strikingly similar to that of the solar system, with …

Only 20 per cent of old field stars have detectable debris discs, leaving open the question of
what disc, if any, is present around the remaining 80 per cent. Young moving groups allow to …

Drastic changes in protoplanets' orbits could occur in the early stages of planetary systems
through interactions with other planets and their surrounding protoplanetary or debris discs …

Context. Debris disks represent the last phase of the evolution of protoplanetary disks
around young stellar objects where planetary systems had most likely already been formed …

As exoplanet surveys reach ever-higher sensitivities and durations, planets analogous to the
solar system giant planets are increasingly within reach. HD 28185 is a Sun-like star known …

This study aims to identify potential exoplanet signals from nearby stars with resolved debris
discs. However, the high activity of many stars with debris discs limits the detection of …

The detection and constraint of the orbits of long-period giant planets is essential for
enabling their further study through direct imaging. Recently, Venner et al.(2024) highlighted …

The long-period giant planet HR 5183 b has one of the most extreme orbits among
exoplanets known to date, and represents a test for models of their dynamical evolution. In …
