When Stellar Metallicity Sparks Planet FormationMoffett Field CA (SPX) Apr 11, 2012 In new research, scientists have attempted to determine the precise conditions necessary for planets to form in a star system. Jarrett Johnson and Hui Li of Los Alamos National Laboratory assert that observations increasingly suggest that planet formation takes place in star systems with higher metallicities. Astronomers use the term "metallicity" in reference to elements heavier than hydrogen and helium, such as oxygen, silicon, and iron. In the "core accretion" model of planetary formation, a ro ... read more |
