From Wikipedia ![]() Assume that a pair ofsolar-massneutron stars are in circular orbits at a distance of 1.89 m (189,000 km). From Wikipedia ![]() The initial collapse of asolar-massprotostellar nebula takes around 100,000 years. From Wikipedia ![]() This dense star, with an estimated 0.6solarmassand 0.028 solar radius, has an apparent magnitude of 17.5. From Wikipedia ![]() In stars of more than approximatelysolarmass, it can take a billion years or more for the core to reach helium ignition temperatures. From Wikipedia ![]() If, however, the mass of the protostar is less than about 0.08solarmass, normal hydrogen thermonuclear fusion reactions will not ignite in the core. From Wikipedia ![]() Thus, radiation dominates in the inner portion ofsolarmassstars. From Wikipedia ![]() Thesolarmassis quite a large unit on the scale of the solar system: 1.9884(2) kg. From Wikipedia ![]() A more modern estimate is 1.00solarmass. From Wikipedia ![]() This activity is caused by matter flowing onto a 65 millionsolarmasssupermassive black hole at the core. From Wikipedia ![]() In a very low-mass star (less than about 0.5solarmass), the core is never hot enough to ignite helium. From Wikipedia ![]() Its mass is 23 times thesolarmasswhile it has a surface temperature of 11,100 kelvins. From Wikipedia ![]() Therefore,solarmassstars have radiative cores with convective envelopes in the outer portion of the star. From Wikipedia ![]() The outer portion ofsolarmassstars is cool enough that hydrogen is neutral and thus opaque to ultraviolet photons, so convection dominates. From Wikipedia ![]() The pulsar is about 1.8solarmassand the companion is about 0.25 solar masses. From Wikipedia ![]() By comparison, the secondary has only 30% of asolarmass. From Wikipedia ![]() The transition in primary energy production from one form to the other spans a range difference of less than a singlesolarmass.
