It has recently been shown that stellar clustering plays an important role in shaping the properties of planetary systems. We investigate how the multiplicity distributions and orbital periods of planetary systems depend on the 6D phase space density of stars surrounding planet host systems. We find that stars in high stellar phase space density environments (overdensities) have a factor of 1.6–2.0 excess in the number of single-planet systems compared to stars in low stellar phase space…

Exploring the link between star and planet formation with Ariel
The goal of the Ariel space mission is to observe a large and diversified population of transiting planets around a range of host star types to collect information on their atmospheric composition.
An upper limit for the growth of inner planets?
The exotic range of known planetary systems has provoked an equally exotic range of physical explanations for their diverse architectures.However, constraining formation processes requires mapping

Stellar clustering shapes the architecture of planetary systems
TLDR
Old, co-moving stellar groups around exoplanet host stars in the astrometric data from the Gaia satellite are identified and it is demonstrated that the architecture of planetary systems exhibits a strong dependence on local stellar clustering in position-velocity phase space.
