... To avoid extensive numerical calculations in the statistical simulations, we treat the continuous evolution of each binary component as a sequence of a finite number of basic evolutionary states (for example, main sequence, red (super)giant, helium (Wolf-Rayet) star,     hot WD), in which stellar parameters significantly differ from each other. ... Figure 2: Schematic representation of the typical evolutionary track of a massive binary system with normal and compact star stages indicated. ...

An Ancient Universe: How Astronomers Know the Vast Scale of Cosmic Time . SUPERNOVA 1987a . This Hubble Space Telescope image shows the remnant of a supernova a star that blew itself to pieces. We first saw the light of the explosion on Earth in 1987, and this image was taken in 1994. The remnant of the explosion itself is the blob of stuff in the center; the rings are regions of material ejected by the star earlier in its death throes. ... Return to An Ancient Universe . ...

... Supernovae physics (from Wikipedia ): A supernova is a stellar explosion that creates an extremely luminous object that is initially made of plasma ionized form of matter. ... The explosion expels much or all of a star's material at a velocity of up to a tenth the speed of light, driving a shock wave into the surrounding interstellar gas. ... Working on a time series of images in the Large Magellanic Cloud he detected a flaring star, possibly a supernova located in a distant galaxy behind the LMC. ...

During the final stages in its life, a star is transformed in ways which remain poorly understood. ... Each transformation is a response to changes in chemical composition in the stellar interior as nuclear reactions convert one source of fuel into another. ... Consequently, the number of stars currently in these late stages of stellar evolution is comparatively small. ...
