Small star at end of stellar evolution
WebHence, in the white dwarf stage of stellar evolution, it is the degeneracy pressure of the electrons, and not of the nuclei, that halts the collapse of the core. White Dwarfs White dwarfs, then, are stable, compact objects with electron-degenerate cores that cannot contract any further. WebProxima Centauri, the closest star to the Sun, at a distance of 4.2 ly (1.3 pc ), is a red dwarf. A red dwarf is the smallest and coolest kind of star on the main sequence. Red dwarfs are by far the most common type of star in the Milky Way, at least in the neighborhood of the Sun, but because of their low luminosity, individual red dwarfs ...
