C.J.H. Science — Making heavy elements by colliding neutron stars "Kilonova" explosions may be signs of heavy element production. Initially two stars with masses greater than about eight times the mass of the Sun are formed in close proximity, orbiting their mutual center of mass. Only when they illuminate these complex radiations, they will search for them in the light coming from the kilonova in order to confirm the origin of all the matter from which everything in space is made.Heavier elements are formed when atoms of lighter elements capture free neutrons and convert them into protons. )Assuming the red point was actually part of the same event as the GRB, the astronomers considered two possibilities: either it was the afterglow of an explosion or it was light emitted by the production of new nuclei. But for deep space, scientists rely on coordinated simultaneous observation of several signals: cosmic rays, neutrinos and - in this case essential - electromagnetic radiation and gravitational waves.Gravitational waves propagate through space in all directions after the collision of two neutron stars. Astronomers detected two spectral lines with a wavelength of about 810 nanometers, which is the wavelength of infrared light on the border with the wavelengths of visible red light. A weak gamma-ray burst was found in conjunction with GW170817 by the Fermi and INTEGRAL satellites, and we determined with our X-ray and radio observations that the beam was pointed away from us. In the cloud of gases formed after the explosion during the collision of two neutron stars, so many neutrons are released. This rapid neutron capture, or r-process, nucleosynthesis, requires dense, neutron-rich material. Most GRBs are located in faraway galaxies.
However, enjoying the fireworks is one thing, and researching and interpreting the collected data is another, especially because they had nothing to compare their observations with.Several groups of scientists worked on the processing and by October 2019, two years after the column, they came to the proof that heavy elements such as gold, platinum or uranium are actually created during kilonova.
Matthew Francis - Jul 18, 2013 1:30 pm UTC The explosion, known as GRB 130603B, appeared on June 3, 2013 (hence the designation); the astronomers performed follow-up observations nine days later using the Hubble Space Telescope and the Magellan/Baade Telescope in Chile.They found a red-colored point of light at the same position in the sky as GRB 130603B and determined both the GRB and the red point were at the same distance from Earth: about 3.9 billion light-years. There are many models that attempt to predict the observed behavior of a kilonova. The name doesn't do much for me, either.) One of the most energetic possibilities is the short gamma-ray burst.
Copyright © needforscience.com Long-duration GRBs are currently thought to be particularly energetic supernovae, or hypernovae, since they occur in regions of vigorous star formation. Just like the black hole binaries already detected by LIGO, neutron star binaries will inspiral as gravitational waves remove energy from their orbits, until eventually they merge. The creation of these elements requires hotter environments than even the cores of stars can provide. Nucleosynthesis is the process that creates new atomic nuclei from pre-existing nucleons (protons and neutrons) and nuclei. Two labs intended for their detection, the so-called LIGO observatory (Observatories of gravitational waves by laser interferometry), in the states of Washington and Louisiana in the USA, and the Virgo interferometer, in Italy, on October 16, 2017 simultaneously recorded the appearance of gravitational waves two minutes before that NASA’s Fermi satellite detected short-lived high-power gamma radiation. Thus, heavy elements were formed, and everything lasted less than a second.Each element in the cloud of gases absorbed and radiated light of a special wavelength, and this data traveled through space all the way to the Chilean telescope. It has not been easy to explain how we could get large amounts of heavy elements, such as the precious metals we can find on Earth today.
