Areas in the mass of the core and heavy elements space correspond to solutions found with different equations of state: SCvH (green), MH13+SCvH (red) and REOS3b (blue area). The space of solutions obtained with REOS3b has shifted towards solutions with a lower mass of heavy elements compared with Miguel et al. (2016). Miguel et al. 2016. We also find fewer solutions that have a high mass of heavy elements for SCvH. The range of solutions for the core mass remain unchanged for SCvH and MH13 and for REOS3b the lower limit is 5 M_⊕ compared with 7 M_⊕ before.
