- W1676861409 abstract "We present a detailed abundance analysis of high-quality HARPS, UVES and UES spectra of 95 solar analogs, 33 with and 62 without detected planets. These spectra have S/N > 350. We investigate the possibility that the possible presence of terrestrial planets could affect the volatile-to-refratory abundance ratios. We do not see clear differences between stars with and without planets, either in the only seven solar twins or even when considering the whole sample of 95 solar analogs in the metallicity range -0.3< [Fe/H] < 0.5 . We demonstrate that after removing the Galactic chemical evolution effects the possible differences between stars with and without planets in these samples practically disappear and the volatile-to-refractory abundance ratios are very similar to solar values. We investigate the abundance ratios of volatile and refractory elements versus the condensation temperature of this sample of solar analogs, in particular, paying a special attention to those stars harbouring super-Earth-like planets." @default.
