Shaw Laureate Michel Mayor and Astronomers Discovered A Triple System of Super-Earths
09 Jul 2008
A team of European astronomers led by Shaw Laureate, Professor Michel Mayor have announced a significant breakthrough in the field of extra-solar planets at an international conference held earlier in France.
With the High Accuracy Radial Velocity Planet Searcher (HARPS) at the ESO La Silla Observatory, the team has found a triple system of super-Earths around the star HD40307. Professor Mayor said that they had made very precise measurement of the velocity of the star HD40307 over the last five years, which clearly revealed the presence of three planets. These planets having 4.2, 6.7 and 9.4 times the mass of the Earth, orbit the star with periods of 4.3, 9.6 and 20.4 days respectively.
Professor Mayor added that they might not yet know if every single star does harbour planets but their recent discovery did make huge progress towards it.
