In astronomy — and astrophysics and cosmology — there are two main kinds of nucleosynthesis, Big Bang nucleosynthesis BBNand stellar nucleosynthesis.
Garain - Yoon Astrophysics research at Notre Dame is directed toward the study of astrophysical origins.
The center supports interdisciplinary research in three basic areas: Notre Dame has joined a consortium of other universities for construction and use of this telescope. Current observational programs involve a variety of telescopes around the world including the Keck observatory in Hawaii and the Hubble Space Telescope.
Ongoing research includes studies in the mysterious dark energy which is accelerating the expansion rate of the universe, studies of distant supernovae and gamma-ray bursts, studies of planet formation Nucleosynthesis in astronomy young stellar systems, and studies of gravitational microlensing to search for dark matter and planets in the Galaxy.
Theoretical Research Ongoing theoretical research includes all aspects of the origin and evolution of the universe, galaxies, stars, planets, and the interstellar medium. The astrophysics theory group has pioneered the development of modern numerical methods for hydrodynamic simulations of complex astrophysical systems.
Theoretical work concerning the formation and evolution of galaxies, stars and the interstellar medium is being investigated with complex adaptive mesh magnetohydrodynamics.
The group is also doing cosmological simulations of the origin and evolution of the very early universe, from the birth at the Planck scale, through inflation and various particle-physics processes, primordial nucleosynthesis, the emission of the cosmic microwave background, and the formation of large-scale structure and galaxies.
These simulations are used to constrain theories for the nature of space-time and the origin of the universe. General relativistic numerical hydrodynamic simulations are also being performed as a means to understand exploding supernovae, black-hole and neutron star formation, and the formation of jets and electromagnetic bursts for accreting systems.
Another focus is theoretical nuclear astrophysics. This included nucleosynthesis in the big bang, in supermassive population III stars, during late stellar evolution AGB starsand explosive nucleosynthesis on accreting white dwarfs novaeaccreting neutron stars X-ray burstsand supernovae.
The nuclear-physics input is derived from nuclear structure and nuclear reaction models. The reaction flow is studied within the time scales of static or explosive stellar burning. Energy generation and nucleosynthesis are calculated and compared with observed luminosities and elemental abundance distributors.In astronomy – and astrophysics and cosmology – there are two main kinds of nucleosynthesis, Big Bang nucleosynthesis (BBN), and stellar nucleosynthesis.
The process is called nucleosynthesis. Dust in the wind-- ashio-midori.com November 21, Astronomers discover stars with carbon atmospheres-- University of Arizona November 18, Scientist seeks to understand nuclear reactions on stars deep underground-- Black Hills Pioneer.
Stellar nucleosynthesis is the theory explaining the creation (nucleosynthesis) of chemical elements by nuclear fusion reactions between atoms within stars. Stellar nucleosynthesis has occurred continuously since the original creation of hydrogen, helium and lithium during the Big Bang.
It is a highly predictive theory that today yields. Teach Astronomy - Nuclear reactions in primordial nucleosynthesisThe ratios of elements found in the oldest gas clouds in the universe contain one of the primary pieces of evidence for the Big Bang.
While stars turn light elements into heavy elements (and supernovae generate even.
The study of the physics of the stars and their role as nucleosynthesis factories owes much to cross-fertilization of different, somehow disconnected fields, ranging from observational astronomy, computational astrophysics, and cosmochemistry to experimental and theoretical nuclear ashio-midori.com: Jordi Jose.
