Explosive Nucleosynthesis in Magnetohydrodynamical Jets from Collapsars II. Heavy-Element Nucleosynthesis of s, r, p-Processes

, 2012
We investigate the nucleosynthesis in a massive star of 70 M_solar with solar metallicity in the main sequence stage. The helium core mass after hydrogen burning corresponds to 32 M_solar.

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 ...

Upper limit to $\Omega_B$ in scalar-tensor gravity theories

, 1997
In a previous paper (Serna & Alimi 1996), we have pointed out the existence of some particular scalar-tensor gravity theories able to relax the nucleosynthesis constraint on the cosmic baryonic density.

Big Bang Nucleosynthesis [PDF]

Nuclear Physics B - Proceedings Supplements, 2002
A review of Big Bang Nucleosynthesis (BBN) is presented. Observations of deuterium and helium-4 are discussed. Some BBN restrictions on non-standard physics, especially on neutrino properties and time-variation of fundamental constants are given.

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 ...

Nuclear Astrophysics

, 2005
Nuclear physics has a long and productive history of application to astrophysics which continues today. Advances in the accuracy and breadth of astrophysical data and theory drive the need for better experimental and theoretical understanding of the ...

Absence of a Lower Limit on Omega_b in Inhomogeneous Primordial Nucleosynthesis

, 1994
We show that a class of inhomogeneous big bang nucleosynthesis models exist which yield light-element abundances in agreement with observational constraints for baryon-to-photon ratios significantly smaller than those inferred from standard homogeneous ...
