The choice that is most likely end for a star that formed from an extremely large nebula would be a black hole. Gravity pulls so much in a black hole that no light exists.
if it is heat flow through a metal, it would be necessary to have a conductor so that the electrons can flow through it (delocalised electrons).
In terms of radiation, it would require a good absorber of heat (e.g. a black surface) so that the thermal energy flows through on the surface area.
