The theoretical world of Hēdran is the 2nd planet of a 7 planet system. It lies within its star's (G1.4) habitable zone, but with a hot jupiter gas giant only ~1 AU away it experiences heavy gravitational flux.
It has been brought to my attention in a previous question that this closeness is unlikely. I have had difficulty finding information as to the limits of planet spacing within a solar system. Outside of that I have found some supporting data that earth-like planets could exist in Hot Jupiter systems. From my knowledge one only had to be outside the hill sphere to be free of significantly dangerous gravitational effects.
Looking at this question posted sometime earlier has helped but not provided concrete answers one way or another.
This article states that hot jupiters between .1 and .5 AU are systems that can contain earth-like planets, and generally have a lower mass for a gas giant.
Is there something I'm not understanding? If I am wholesale wrong about my gas giant being so close to the homeworld I would appreciate as to why and will gladly make changes.
Apologies for the disjointed question and lack of knowledge on the subject. And thank you for any and all help!
