No mention was made in this article of the possibility that, being so close to its star and having a 13-day orbital period, the planet would keep the same surface to the star. Having one side baked by unrelenting sunlight and the other side frozen would leave only a narrow ring between eternal day and eternal night that might have what could be called average conditions suitable for liquid water. I would think that the probability for life to start and survive would be very unlikely.

In some models of planets, especially those with atmospheres, heat flows between the day and night sides, so the temperatures aren’t so extreme.
