Assume that a pair of solar-mass neutron stars are in circular orbits at a distance of 1.89 m (189,000 km). From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The initial collapse of a solar-mass protostellar nebula takes around 100,000 years. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. This dense star, with an estimated 0.6 solarmass and 0.028 solar radius, has an apparent magnitude of 17.5. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. In stars of more than approximately solarmass, it can take a billion years or more for the core to reach helium ignition temperatures. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. If, however, the mass of the protostar is less than about 0.08 solarmass, normal hydrogen thermonuclear fusion reactions will not ignite in the core. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Thus, radiation dominates in the inner portion of solarmass stars. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The solarmass is quite a large unit on the scale of the solar system: 1.9884(2) kg. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. A more modern estimate is 1.00 solarmass. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. This activity is caused by matter flowing onto a 65 million solarmass supermassive black hole at the core. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. In a very low-mass star (less than about 0.5 solarmass), the core is never hot enough to ignite helium. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Its mass is 23 times the solarmass while it has a surface temperature of 11,100 kelvins. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Therefore, solarmass stars have radiative cores with convective envelopes in the outer portion of the star. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The outer portion of solarmass stars is cool enough that hydrogen is neutral and thus opaque to ultraviolet photons, so convection dominates. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The pulsar is about 1.8 solarmass and the companion is about 0.25 solar masses.
