3rd planetary companion around HIP 14810. And laying in habitable zone, perhaps.

Habitable zone? Using the radius and T_eff in the paper, I get a luminosity of 0.8 times solar. Accounting for eccentricity, the equivalent distances of planets c and d scaled to our solar system are 0.6 AU and 2.1 AU. A planet that's hotter than Venus or one that receives only half as much energy as Mars, take your pick...

And they're gas giants anyway.

I've said perhaps, indeed. Razz

Lazarus beat me to it, was just about to post on that. Lol I think "perhaps" is a stretch.
