Planets with few heavy elements
So far, astronomers considered heavy elements such as oxygen, silicon, carbon and iron to be at a minimum proportion to form planets around stars. At the University of Texas they have seen that a constellation star of Hercules is surrounded by very few heavy elements and yet two planets are spinning. It is very rare that these stars have planets. More than a hundred stars with planets have been identified, of which only the environment of this and another that they have identified are now scarce in heavy elements.
