  "abstract": "Ever since their discovery, hot Jupiters have been one of the most studied types of exoplanets to exist thanks to their significant size, their proximity to their host star, and their significant departure from anything present in our solar system. Yet, the details of their formation and evolution remain unclear, including their connection, if any, to the wider-orbiting warm-Jupiter population. In this work, we present the discovery of K2-232c, an eccentric cold Jupiter ( P = 195 0 − 120 + 140 days, e = 0.35 2 − 0.076 + 0.095 , M sin i = 5.3 1 − 0.45 + 0.48 M J ) companion in a known warm Jupiter ( P = 11.1684377 ± 0.0000010 days, e = 0.24 5 − 0.024 + 0.023 , M = 0.42 7 − 0.036 + 0.039 M J ) system. Placing this system in context with the literature, we find that cold-Jupiter eccentricities are generally higher in hot-Jupiter systems as compared to warm-Jupiter systems, suggesting the formation of hot Jupiters is more dynamically violent than warm Jupiters. This adds further evidence to the claim that these two populations are independent from one another with cold Jupiters appearing to play a crucial role in shaping the formation of both.",
