تعريف brown dwarf في الإنجليزية الإنجليزية القاموس.
A star that is typically about the volume of the planet Jupiter, which has mass approaching that of a star, but insufficient to ignite its elements and cause it to burn as a true star, except that of deuterium, and sometimes lithium
A celestial body that resembles a star but does not emit light because it is too small to ignite internal nuclear fusion. The planet Jupiter is a small brown dwarf
A celestial body that resembles a star but does not emit light because it is too small to ignite internal nuclear fusion. The planet Jupiter is a small brown dwarf. Astronomical object intermediate in mass between a planet and a star. Sometimes described as failed stars, brown dwarfs are believed to form in the same way as stars, from fragments of an interstellar cloud that contract into gravitationally bound objects. However, they do not have enough mass to produce the internal heat that in stars ignites hydrogen and establishes nuclear fusion. Though they generate some heat and light, they also cool rapidly and shrink; they may differ from high-mass planets only in how they form
