In a simulation of a 10 million year span, this planet swept away all test particles "except for a narrow region near the 8:3 resonance". There can be no planets in this star's habitable zone. Observation has ruled out any planet over 0.7 Jupiter mass within a year period.
Eccentric Jupiter
An eccentric Jupiter is a Jovian planet that orbits its star in an eccentric orbit. Eccentric Jupiters may disqualify a planetary system from having Earth-like planets in it because a massive gas giant with an eccentric orbit may remove all Earth mass planets from the habitable zone.To date, it...
