2200 celsius would melt not only Basalt but also Komatiite.

This planet is probably a lava droplet, all the magma gas would have gone ages ago.

Interesting bit is that the presence of a companion star in wide orbit results in tidal effects that gradually jog planets in the stable orbit zone into the central star with time.

The exact same effect occurs with Jupiter's Galilean satellites with the innermost satellite already lost and the last remnants (The Amalthea group) are now covered in volcanic gunk from Io, which will be the next to go. This tidal effect is strongest in the orbital plane of the main bodies (ie. Sun,Jupiter or Alpha Centauri A, & B)and decreases with increasing orbital inclination of satellite objects.

This means that the planet now seen would initially have orbited much further away, and its rate of inward drift would depend on its orbital inclination.
Alpha Centauri is older and more metal rich than the sun so the outer part of the stable orbit zone around each star is probably empty. Both stars would however likely harbour remnant planets of the initial system close to the central star.

Sadly for the one just discovered, any fossil aliens would have melted a long time ago.

Uh, was it earth itself?

That newly-discovered planet has a huge moon circling about it, appropriately named Kardashian.
