The Super Earth-Cold Jupiter Relations
Wei Zhu (CITA), Yanqin Wu

TL;DR
This study reveals a strong correlation between super Earths and cold Jupiters around Sun-like stars, suggesting they share similar origins and are often found together, with implications for planetary system formation theories.
Contribution
It provides the first comprehensive statistical analysis linking super Earths and cold Jupiters, demonstrating their frequent co-occurrence and shared formation conditions.
Findings
Cold Jupiters are three times more common around super Earth hosts.
Nearly 90% of cold Jupiters are accompanied by super Earths.
Systems like our own, with cold Jupiters but no super Earths, are very rare.
Abstract
We report relations between inner ( au) super Earths (planets with mass/radius between Earth and Neptune) and outer ( au) giant planets (mass , or cold Jupiters) around Sun-like stars, based on data from both ground-based radial velocity (RV) observations and the Kepler mission. We find that cold Jupiters appear three times more often around hosts of super Earths than they do around field stars. Given the prevalence of the super Earth systems, their cold Jupiters can account for nearly all cold Jupiters. In other words, cold Jupiters are almost certainly () companied by super Earths. A few corollaries follow: (1) around metal-rich ([Fe/H]) stars, the fraction of super Earths with cold Jupiters can rise to or higher; (2) the inner architecture can be strongly impacted by the outer giant and we report some observational evidence for this; (3)…
