Representative lifetimes of stars as a function of their masses The change in size with time of a Sun-like star Artist's depiction of the life cycle of a Sun-like star, starting as a main-sequence star at lower left then expanding through the subgiant and giant phases, until its outer envelope is expelled to form a planetary nebula at upper right Chart of stellar evolution
Diagram of stellar evolution, showing the various stages of stars with different masses. A black dwarf is a theoretical stellar remnant, specifically a white dwarf that has cooled sufficiently to no longer emit significant heat or light.
Researchers have discovered a white dwarf (a dead star), with an oxygen atmosphere surrounding it -- the first of its kind. Astronomers managed to pick up the star from spectral lines: colored ...
Pulsars are formed when a star dies, exploding in a supernova and leaving behind a tiny, dead star. They are just 20 kilometres across, and spin extremely fast with a powerful magnetic field.
It would arise when a star "in the transitional range (~8 to 10 solar masses) between white dwarf formation and iron core-collapse supernovae", and with a degenerate O+Ne+Mg core, [139] imploded after its core ran out of nuclear fuel, causing gravity to compress the electrons in the star's core into their atomic nuclei, [140] [141] leading to a ...
A "zombie star" could possibly rise from the dead on Halloween night, according to space experts. T Coronae Borealis, also known as the "Blaze Star," is expected to explode violently in the near ...
Often when a star is a member of a pair of close-orbiting binary stars, the tidal attraction of the gasses near the center of mass is sufficient to pull gas from one star onto its partner. This effect is especially prominent when the partner is a white dwarf, neutron star, or black hole. Mass loss in binary systems has particularly interesting ...
Bee Gees star Maurice died unexpectedly in 2003, aged 53, due to complications from a twisted intestine. His twin brother, Robin, died in 2012, aged 62, from liver and kidney failure after ...
