Refueling the Magic Furnace: Kilonova 2017 Rewrites the Story of Element Origins

Journal of Big History, 2018
For more than half a century, we have understood element creation in the stars—described in Marcus Chown’s colorful image as “the magic furnace.” From 1958 until 2017, supernova explosions were thought to be the primary site of element creation above ...

Neutrino Astrophysics [PDF]

arXiv, 2008
I review the current status of neutrino astrophysics, including solar neutrinos; atmospheric neutrinos; neutrino mass and oscillations; supernova neutrinos; neutrino nucleosynthesis (Big Bang nucleosynthesis, the neutrino process, the r-process); neutrino cooling and red giants; and high energy neutrino astronomy.

Production of Lithium and Heavy Elements in AGB Stars Experiencing PIEs

Galaxies
Asymptotic giant branch (AGB) stars can experience proton ingestion events (PIEs), leading to a rich nucleosynthesis. During a PIE, the intermediate neutron capture process (i-process) develops, leading to the production of trans-iron elements.

Neutrinos and Big Bang Nucleosynthesis [PDF]

Physica Scripta, 2005
According to the standard models of particle physics and cosmology, there should be a background of cosmic neutrinos in the present Universe, similar to the cosmic microwave photon background. The weakness of the weak interactions renders this neutrino background undetectable with current technology.

Direct and Indirect Measurements of the ¹⁹F(p,α)¹⁶O Reaction at Astrophysical Energies Using the LHASA Detector and the Trojan Horse Method

Universe
Fluorine is one of the most interesting elements in nuclear astrophysics. Its abundance can provide important hints to constrain the stellar models since fluorine production and destruction are strictly connected to the physical conditions inside the ...

Explosive Nucleosynthesis

, 2022
Cosmic nucleosynthesis had been one of INTEGRAL’s major science targets. The SPI spectrometer delivered important measurements, both from targets of opportunity in the form of stellar explosions and their shortlived radionuclides, and from cumulative emission of long-lived radioactive isotopes. We review the lessons learned on explosive nucleosynthesis
