See Tau Ceti in fiction and on this blog. (Scroll down.) "Tau Ceti II" as a post title means either that the post is about the planet or that it is the second post about the star.
In Poul Anderson's After Doomsday, the sub-arctic region of Tau Ceti II is described as follows:
safe;
rusty dunes;
a few thorn-plants;
a glaring red sun;
hot dry air full of carbon dioxide.
As a habitable planet of a nearby star, Tau Cet II makes sense as a place for the U.S.S. Benjamin Franklin to go after Earth has been destroyed but it plays no role in the rest of the novel. I was surprised to learn how many works of sf feature planets of this star.
