Scientific paper

In the past decade Astronomers have found approximately 120 planets orbiting Sun-like stars. Currently, the detection capabilities restrict the findings to very massive objects. It is presumed some extra-solar planets could be Earth-like in composition. The internal conditions and structures of these planets would have similarities with the Earth's, but due to their much larger mass and different conditions (i.e. Extremely hot surface temperature) their properties are expected to differ considerably. With the use of EOS for terrestrial planets and physical laws we are obtaining radial structure profiles (density, pressure, mass, temperature) for massive Earth-like planets. Parameter space in properties is being explored to study the implications, such as the presence of a liquid core and thermal history of these planets.
