Lithium-poor “twin” stars to the Sun targetted. Stars similar to the Sun that have a low lithium content are strong candidates for hosting planets according to a study led by researchers from the Instituto de Astrofísica de Canarias (IAC). Lithium, one of the lightest elements known and easily detected through spectral analysis; provides a new trail to follow in the search for planetary systems like ours own The results, published in the journal Nature, were obtained from a sample of about 500 stars. Examination of the data showed that the low proportion of lithium in Sun-like stars is
