The correlation between inner super-Earths (SEs) and outer cold Jupiters (CJs) provides an important constraint on the formation and dynamical evolution of planetary systems. Previous studies have suggested a positive […]

Saturns, But Not Super-Jupiters, Occur More Frequently In The Presence Of Inner Super-Earths
Studies from recent years have reached different conclusions regarding how frequently super-Earths are accompanied by long period giant planets and vice versa. This relation has been predicted to be mass […]

Cold Jupiters And Small Planets: A Search For Correlations With The Largest Exoplanet Samples
Finding out whether there is any correlation between the presence of short-period small planets (SPs) with P≲100 d (a≲0.4 AU) and 1<Mp<20 M⊕ and that of outer cold Jupiters (CJs) […]

Mutual Occurrence Ratio of Planets. I. New Clues to Reveal Origins of Hot- and Warm-Jupiter from the RV Sample
Many studies have analyzed planetary occurrence rates and their dependence on the host’s properties to provide clues to planet formation, but few have focused on the mutual occurrence ratio of […]
![The plots of stellar metallicity ([Fe/H]) versus planetary orbital period for all transiting planets from the NASA exoplanet archive. Tranet stands for transiting planet. The transiting planets are split into four groups based on the multiplicity of their systems and are placed on four different panels. The two dotted vertical lines split the metallicity range into three metallicity regions, namely, sub-solar, solar, and super-solar. While low-multiplicity systems are evenly distributed across hosts of all metallicities there is a paucity of high-multiplicity systems around hosts of high metallicity indicating the effect of cold Jupiters on the inner planet multiplicity. -- astro-ph.EP](https://i0.wp.com/astrobiology.com/wp-content/uploads/2024/02/Constraining-Planetary.png?resize=1200%2C717&ssl=1)

Constraining Planetary Formation Models Using Conditional Occurrences of Various Planet Types
We report the conditional occurrences between three planetary types: super-Earths (m sin i < 10 M⊕, P < 100 days), warm Jupiters (m sin i > 95 M⊕, 10 < […]
