History. In 1920, Arthur Eddington proposed that stars obtained their energy from nuclear fusion of hydrogen to form helium and also raised the possibility that the heavier elements are produced in stars.
25 Οκτ 2021 · The detectors picked up gravitational waves, or ripples through space-time, that originated 130 million light years from Earth, from a collision between two neutron stars — collapsed cores of massive stars, that are packed with neutrons and are among the densest objects in the universe.
Some neutron stars emit beams of electromagnetic radiation that make them detectable as pulsars, and the discovery of pulsars by Jocelyn Bell Burnell and Antony Hewish in 1967 was the first observational suggestion that neutron stars exist.
29 Νοε 2022 · The expected RSG progenitors, with its large luminosity in the optical, make it practically possible to search for a progenitor star in pre-SN images mainly provided by Hubble Space Telescope archival data; it is called “the direct progenitor detection.”
