16 Cygni A/B abundances: no terrestrial planets?

Detailed Abundances of the Solar Twins 16 Cygni A and B: Constraining Planet Formation Models

Study of the chemical abundances of the sunlike stars in the 16 Cygni system in the light of the fact that 16 Cygni B is a planet-host but 16 Cygni A is not. The abundances may suggest that neither star formed terrestrial planets... unfortunately testing this is going to be challenging!
