"...but I'll take a guess that the planet is a little bigger and a little lighter than the given values..."

Yeah, those numbers don't seem plausible: 1.4 x size & 7 x mass means something more dense than an iron core, even if the core is relatively larger than Earth's. The problem is that you can fusion elements, from hydrogen upwards and still gain energy, until you reach iron but at that point further fusion, to produce heavier elements, costs energy and this only occurs at the end of a very large star's life and in relatively small amounts.
