Latest Compact star Stories
The intermittent light emitted by pulsars, the most precise timekeepers in the universe, allows scientists to verify Einstein's theory of relativity, especially when these objects are paired up with another neutron star or white dwarf that interferes with their gravity.
The densely packed matter of a pulsar spins at incredible speeds, and emits radio waves that can be observed from Earth, but how neutron stars emit these waves is still a mystery.
A team of Japanese researchers has discovered evidence that a yellow supergiant was, in fact, the progenitor for a recently discovered supernova -- a discovery which they say raises serious questions regarding our understanding of the evolution of massive stars.
Two very different models explain the possible origin of Type Ia supernovae, and different studies support each model. New evidence shows that both models are correct - some of these supernovae are created one way and some the other.
Last year's discovery of the nearest Type Ia supernova in decades – captured only 11 hours after it exploded – allowed astronomers to finally cinch the identity of the stars behind these explosions, which have become key measures of cosmic distance.
Older stars may have to slow down their rotations before exploding as supernovae.
An international team of astronomers have discovered a unique and exotic star system with a very cool methane-rich (or T-) dwarf star and a â€˜dyingâ€™ white dwarf stellar remnant in orbit around each other.
The question of what causes a Type Ia supernova is one of the great unsolved mysteries in astronomy.
WASHINGTON, Feb 17 /PRNewswire-USNewswire/ -- New findings from NASA's Chandra X-ray Observatory have provided a major advance in understanding a type of supernova critical for studying the dark energy that astronomers think pervades the universe.
Evidence for a thin veil of carbon has been found on the neutron star in the Cassiopeia A supernova remnant.
Stellar Evolution -- Stellar evolution is the process of formation, life, and death of stars. It is one of the major topics of cosmogony. Star Birth and Life A star starts out as an enormous cloud of gas and dust many light-years across. Star formation begins when the cloud begins to condense under its own gravity. The processes that initiate this contraction are not fully understood. The cloud fragments fuse into stellar mass clouds known as protostars. Protostars do not emit...
