    Chemical Abundances of Volatiles and Refractories in Solar Analogs with and without Planets: No Relation with Terrestial Planets
    We present the abundances of volatile and refractory elements in the atmospheres of 95 solar analogs, 24 planet hosts and 71 "single" stars, to investigate its...
