In astronomy, an iron star is a hypothetical type of compact star. Unrelatedly, the term "iron star" is also used for blue supergiants which have a forest of forbidden FeII lines in their spectra. They are potentially quiescent hot luminous blue variables. Eta Carinae has been described as a prototypical example.

As the cloud collapses, it fragments into smaller regions, which themselves contract to form stellar cores. These protostars rotate faster and increase in temperature as they condense, and are surrounded by a protoplanetary disk out of which planets may later form. diamond orthopedic llc

As the universe churns and new stars and … WebIf the star isn't large enough, nuclear fusion may stop, before the core of the star is fused to iron, since very high temperature (more than 2 billion Kelvin) and pressure are needed to fuse silicon to iron. This way the core may collapse earlier. The collapse releases energy responsible for much of the luminosity of the supernova.

WebOct 14, 2009 · Second, most stars don't even fuse all the elements up to iron. Third, for the stars that do fuse elements up to iron, the heavy elements are almost always blown off in the ensuing supernova explosion, leaving a neutron star. Again, I don't see any way this neutron star could become an "iron star". Jun 7, 2009 #3 protonchain 97 0 WebIron, however, is the most stable element and must actually absorb energy in order to fuse into heavier elements. The formation of iron in the core therefore effectively concludes fusion processes and, with no energy to support it against gravity, the star begins to collapse in on itself. The star has less than 1 second of life remaining.
