Stars outside of the Solar System have been featured as settings in works of fiction since at least the 1600s, though this did not become commonplace until the pulp era of science fiction. Stars themselves are rarely a point of focus in fiction, their most common role being an indirect one as hosts of planetary systems. In stories where stars ...
Temperature description: . T eff - Temperature Effect, usually associated with luminous object; T max - Temperature Maximum, usually associated with non-luminous object; T avg - Temperature Average, usually associated with non-luminous object
Luminosity is an absolute measure of radiated electromagnetic energy per unit time, and is synonymous with the radiant power emitted by a light-emitting object. [1] [2] In astronomy, luminosity is the total amount of electromagnetic energy emitted per unit of time by a star, galaxy, or other astronomical objects. [3] [4]
The rate of infall is bound by the Eddington limit, which shows that the luminosity of the resultant star (in Watts) would be equal to approximately six times its mass (in kilograms). It has been suggested that a black hole could be moved into position by placing an asteroid in orbit around the black hole, and using a mass driver to direct a ...
In astronomy, absolute magnitude (M) is a measure of the luminosity of a celestial object on an inverse logarithmic astronomical magnitude scale; the more luminous (intrinsically bright) an object, the lower its magnitude number.
A super-luminous supernova (SLSN, plural super luminous supernovae or SLSNe) is a type of stellar explosion with a luminosity 10 or more times higher than that of standard supernovae. [1] Like supernovae, SLSNe seem to be produced by several mechanisms, which is readily revealed by their light-curves and spectra.
Intrinsic variables, whose luminosity actually changes periodically; for example, because the star swells and shrinks. Extrinsic variables , whose apparent changes in brightness are due to changes in the amount of their light that can reach Earth; for example, because the star has an orbiting companion that sometimes eclipses it .
A hypergiant (luminosity class 0 or Ia +) is a very rare type of star that has an extremely high luminosity, mass, size and mass loss because of its extreme stellar winds.The term hypergiant is defined as luminosity class 0 (zero) in the MKK system.
