Abstract: This paper explores hot Jupiter core formation much nearer to the star than the traditional in-situ model suggests. We propose that the protoplanetary disk and the hot Jupiter core form concurrently during a star's infancy, when cooler temperatures favor agglomeration near the inner disk. Building on the in-situ model's core principles, our model estimates inner disk formation at a radial distance of about 1.5 times the stellar radius. Within this dense inner region, the Headwind Effect and the cooler temperatures play a crucial role in the formation of the hot Jupiter core. By utilizing the data available on the NASA Exoplanet Archive[1], we conducted a numerical analysis on six hot Jupiter systems with sufficient data and our findings provide compelling evidence in favor of our hypothesis that — core formation likely occurred within the inner disk region during the early stages of stellar evolution.
