The atmospheric composition data suggests this planet could have a stable climate. The orbital period is particularly interesting for potential biosignature detection.
I agree with Dr. Chen. The temperature range falls within the habitable zone parameters. We should prioritize this for JWST observation time.
Has anyone analyzed the tidal locking probability? Given the orbital period and distance from the host star, this could affect habitability significantly.
