Baby Star

by admin, 26.08.2012

Artists impression of a baby star still surrounded by a protoplanetary disc in which planets are forming. Using ESOs very successful HARPS spectrograph, a team of astronomers has found that Sun-like stars which host planets have destroyed their lithium much more efficiently than planet-free stars. This finding does not only shed light on the low levels of this chemical element in the Sun, solving a long-standing mystery, but also provides astronomers with a very efficient way to pick out the stars most likely to host planets.
