How is heat in stars made
WebThe Earth's uranium had been thought to be produced in one or more supernovae over 6 billion years ago. More recent research suggests some uranium is formed in the merger of neutron stars. Uranium later became enriched in the continental crust. Radioactive decay contributes about half of the Earth’s heat flux.

Web23 jul. 2024 · When mid-sized stars, like the Sun, run out of hydrogen, their cores will contract and heat up. The outer layers of gas will expand and the stars will become red giant stars. Eventually when the core of a red giant star cools, the remaining gas will float into space, forming a planetary nebula.

WebThe amount another body is heated by a star with luminosity L is quantified by its effective temperature : T e f f = ( L ( 1 − a) 16 π σ D 2) 1 / 4 where a is the albedo, D is the distance to the other body, and σ is the Stefan-Boltzmann constant. If the luminosity is given, then there is no direct dependence on the size of the star.
