Population I star disk greater than 1000 Kelvin determined from proper motion and radial velocity which depends on luminosity class from the point of view of Earth's orbit Baade (1944) from the point of view of Earth which is diffused out from the hotter core gravitational contraction and or fusion which takes place primarily within the core star catalog star hydrogen, helium greater than 0.08 the sun's mass disk star Youngest observed stars, like our sun, formed from hydrogen, helium, and a large range of heavier elements (like carbon and oxygen) believed to have been created in the interiors of earlier Population II stars and Population III stars and then blown out into space.

Central body of solar system. It takes about 1-10 million years for photons to diffuse from the Sun's interior to its surface. About 3% of the energy radiated is in the form of neutrinos.
