| 例句 | The low solar neutrino flux probably does not put our view of stellar nucleosynthesis in jeopardy, but it surely means something important. Cosmos 1980-01-01T00:00:00Z Hoyle also realized that if stars imploded they would liberate huge amounts of heat–100 million degrees or more, enough to begin to generate the heavier elements in a process known as nucleosynthesis. A Short History of Nearly Everything 2003-05-06T00:00:00Z Thus, it is an indicator of the nucleosynthesis of heavy elements. Exploding stars 2023-11-02T04:00:00Z Helium’s origins go back to just a few minutes after the big bang, when hydrogen, helium and a bit of lithium were produced during what is called big bang nucleosynthesis. Some of Earth’s Most Famous Art Started with Stardust 2023-07-04T04:00:00Z The creation of new chemical elements is called nucleosynthesis. Astronomy 2016-10-13T00:00:00Z In it, the authors argued that nearly all of the chemical elements, from aluminum to zinc, are forged in the bodies of stars, a process now called stellar nucleosynthesis. E. Margaret Burbidge, Astronomer Who Blazed Trails on Earth, Dies at 100 2020-04-06T04:00:00Z In its younger days, Cassiopeia A began a process called nucleosynthesis, during which hydrogen and helium began fusing in its core to create heavier elements. See How a Massive Supernova Released the Building Blocks of Life 2018-01-10T05:00:00Z Bravo, E. & Martnez-Pinedo, G. Sensitivity study of explosive nucleosynthesis in type Ia supernovae: Modification of individual thermonuclear reaction rates. Solar abundance ratios of the iron-peak elements in the Perseus cluster 2017-11-12T05:00:00Z Another, more plausible, source of error comes from the uncertainties in nuclear physics, such as the nuclear mass model used in the r-process nucleosynthesis calculation. The X-ray counterpart to the gravitational-wave event GW170817 : Nature : Nature Research 2017-10-15T04:00:00Z Only after the cosmos had cooled sufficiently — within in the first 20 minutes after the Big Bang — did they combine to form nuclei in a process called nucleosynthesis. Neutron death mystery has physicists stymied 2014-05-12T04:00:00Z Only after the cosmos had cooled sufficiently—within in the first 20 minutes after the big bang—did they combine to form nuclei in a process called nucleosynthesis. Neutron Death Mystery Has Physicists Stymied 2014-05-13T11:00:00Z The key to the formation of gold — and other elements heavier than iron — is thought to primarily lie in high-energy stellar nucleosynthesis via so-called “r-process” reactions. Scanning For Galactic Gold 2013-10-30T10:44:00Z Albiac says the project was inspired by nucleosynthesis, the process by which matter combines to form new atomic nuclei. Cosmic portraits and out-of-this-world sweet treats 2013-08-26T17:22:45Z However, his lasting legacy was in the field of stellar nucleosynthesis where, working with three other scientists, he helped to unravel the process by which chemical elements are made inside stars. Sir Fred Hoyle 2011-03-18T00:57:46Z “For Big Bang nucleosynthesis, right now the neutron lifetime is the input with the largest uncertainty on it, so by improving the neutron lifetime, you can improve those predictions,” Nico adds. Neutron death mystery has physicists stymied 2014-05-12T04:00:00Z “All sorts of dark matter candidates might actually play a role in big bang nucleosynthesis,” says theoretical physicist Susan Gardner of the University of Kentucky. Neutron Death Mystery Has Physicists Stymied 2014-05-13T11:00:00Z “All sorts of dark matter candidates might actually play a role in Big Bang nucleosynthesis,” says theoretical physicist Susan Gardner of the University of Kentucky. Neutron death mystery has physicists stymied 2014-05-12T04:00:00Z If nucleosynthesis predictions turn out not to match evidence from astrophysical observations of the abundance of helium, for example, exotic physics just might be at work.
