TL;DR
This study investigates the potential correlation between short-period small planets and outer cold Jupiters around solar-type stars, finding no strong overall correlation but hints of a link at higher metallicities and masses.
Contribution
It provides a homogeneous analysis of occurrence rates of cold Jupiters in systems with small planets across different metallicities and stellar masses, clarifying previous conflicting results.
Findings
Occurrence rate of CJs in SP systems is about 11%.
No significant correlation between SPs and CJs overall.
SP system architecture depends on CJ eccentricity.
Abstract
Determining whether there is any correlation between the presence of short-period small planets (SPs) with () and and that of outer cold Jupiters (CJs) with and around solar-type stars may provide crucial constraints on models of formation and/or migration of SPs. However, discrepant results regarding the occurrence rates of CJs in SP systems have been reported in the literature, with some recent studies suggesting a strong SP-CJ correlation but only at super-solar metallicities and/or masses of the host stars. Here, we homogeneously recomputed the occurrence rates of CJs at average, sub-solar (), solar (), and super-solar () metallicity as well as at average and subintervals of stellar mass, namely 0.6-0.8, 0.8-1.0, and 1.0-1.2 , using (i) a…
