If you allow me the license, I thought I would add a marginally off-topic post; perhaps still useful if comparisons to Earth are intended. It involves changes to our own solar system, rather than planets formed from scratch in a binary system, so admittedly not the same.
I was rewatching the movie "2010" recently, which ends (I assume this is no spoiler by now) with Jupiter becoming a second sun. I am no physicist myself, but perhaps many of the other posters may confirm my Wikipedia speculation that this would certainly be no paradise for us.
First, if we are worrying about global warming, now imagine adding a second sun sourcing heat to the planet. But this is not really the worst.
For Jupiter to emit visible light, it would have to increase its mass at least 70-80 times (fusion of elements other than hydrogen may start to occur at a smaller mass, but these would only make it glow in the infrared, like what we know as "brown dwarf" stars; for a shiny second sun you really need to fuse hydrogen). But, as the mass of Jupiter increases that much, it will also start falling towards the sun. Guess who is in the middle. At the very least, a large asteroid belt is. So now you have sort of a kitchen blender splashing rocks at the outskirts of your planetary system. But this is not still the worst.
As Jupiter normally orbits the sun, its present mass makes the sun "wobble" - but not by much: just about as much as the sun's radius, but not really much more. A Jupiter that is 70-80 more massive would make the wobbling extremely close to the orbit of Mercury, at least at Jupiter's current distance (granted, less so as Jupiter starts falling in). Now Mercury gets into a violent eccentric orbit; it may or may not fall into the sun, but it may eventually get fractured in pieces by the violence of its new orbit. So now you have another splashing blender in the middle. But this is not yet the worst.
The rest of the inner planets, Venus, Earth and Mars, will likely leave their almost-circular orbits acquired after billions of years of relative quietness. So now, instead of some dozen degrees of temperature difference per year, your planet (assuming it doesn't smash into something, which it eventually will) may likely have a couple hundred degrees of difference between summer and winter. During the summer, lava will run the surface and stones will melt; in the winter, you will be breathing liquid nitrogen instead of air. Bad for your health.
As said, not the same as the OP's request. But the post was intended to illustrate how relatively peaceful, boringly circular our neighborhood is. And how very different life may have to be (perhaps even subterranean, away from the surface; perhaps without an atmosphere at all) in order to survive planets in eccentric orbits, subject to violent tidal forces and temperature extremes.
