Hey, Hotter than the sun only goes for the surface. The core and the corona are much hotter. Whether electrons get separated from nuclei or nuclear fusion should start to occur also depends on pressure... But the question itself pertains to the code and the application of Newton's equations of motion for particle based systems at very high temperatures. And there's nothing that should prohibit that. There are practical issues, of course. The state of the matter you intend to simulate, the force field, and the time step, definitely.
