star (stär)n.1. a. A self-luminous celestial body consisting of a mass of gas held together by its own gravity in which the energy generated by nuclear reactions in the interior is balanced by the outflow of energy to the surface, and the inward-directed gravitational forces are balanced by the outward-directed gas and radiation pressures. b. Any of the celestial bodies visible at night from Earth as relatively stationary, usually twinkling points of light. c. Something regarded as resembling such a celestial body. 2. A graphic design having five or more radiating points, often used as a symbol of rank or merit. 3. a. An artistic performer or athlete whose leading role or superior performance is acknowledged. b. One who is highly celebrated in a field or profession. 4. a. An asterisk (*). b. The star key on a telephone: For customer service, press star. 5. A white spot on the forehead of a horse. 6. A planet or constellation of the zodiac believed in astrology to influence personal destiny. 7. stars The future; destiny. Often used with the. adj.1.

star (stär)1. A large, spherical celestial body consisting of a mass of gas that is hot enough to sustain nuclear fusion and thus produce radiant energy. Stars begin their life cycle as clouds of gas and dust called nebulae and develop, through gravitation and accretion, into increasingly hot and dense protostars. In order to reach the temperature at which nuclear reactions are ignited (about 5 million degrees K), a protostar must have at least 80 times the mass of Jupiter. For most of its life a star fuses hydrogen into helium in its core, during which period it is known as a dwarf star and is classed according to its surface temperature and luminosity (or spectral type) on a continuum called the main sequence in the Hertzsprung-Russell diagram. When a star exhausts the hydrogen in its core, it typically develops into one of several non-main-sequence forms depending on how massive it is. Smaller stars, with masses less than eight times that of the Sun, become red giants and end their lives, after blowing away their outer layers, as white dwarfs. More massive stars become supergiants and end their lives, after exploding in a supernova, as either a neutron star or ablack hole. 2. Any of the celestial bodies visible to the naked eye at night as fixed, usually twinkling points of light, including binary and multiple star systems. |
