star | celestial body | A celestial object that generates energy by means of nuclear fusion at its core. To do this it must have more than about 0.08 the sun's mass. If, for instance, the planet Jupiter were some fifty to one hundred times more massive than it is, fusion reactions would transpire in its core and it would be a star. See planet. |
asymptotic branch star | star | Globular cluster stars, which are found in that part of the HR diagram that connects the top pf the giant tip with the horizontal branch stars. |
