Title: Active–Sterile Neutrino Oscillations in Neutrino-driven Winds: Implications for Nucleosynthesis

Abstract

A protoneutron star produced in a core-collapse supernova (CCSN) drives a wind by its intense neutrino emission. We implement active–sterile neutrino oscillations in a steady-state model of this neutrino-driven wind to study their effects on the dynamics and nucleosynthesis of the wind in a self-consistent manner. Using vacuum mixing parameters indicated by some experiments for a sterile ν_s of ~1 eV in mass, we observe interesting features of oscillations due to various feedback. For the higher ν_s mass values, we find that oscillations can reduce the mass-loss rate and the wind velocity by a factor of ~1.6–2.7 and change the electron fraction critical to nucleosynthesis by a significant to large amount. In the most dramatic cases, oscillations shift nucleosynthesis from dominant production of ⁴⁵Sc to that of ⁸⁶Kr and ⁹⁰Zr during the early epochs of the CCSN evolution.

Potential Impact of Fast Flavor Oscillations on Neutrino-driven Winds and Their Nucleosynthesis

Journal Article Xiong, Zewei ; Sieverding, Andre ; Sen, Manibrata ; ... - The Astrophysical Journal (Online)

The wind driven by the intense neutrino emission from a protoneutron star (PNS) is an important site for producing nuclei heavier than the Fe group. Because of certain features in the neutrino angular distributions, the so-called fast flavor oscillations may occur very close to the PNS surface, effectively resetting the neutrino luminosities and energy spectra that drive the wind. Using the unoscillated neutrino emission characteristics from two core-collapse supernova simulations representative of relevant progenitors at the lower and higher mass end, we study the potential effects of fast flavor oscillations on neutrino-driven winds and their nucleosynthesis. We find that suchmore »« less

Fission cycling in supernova nucleosynthesis: Active-sterile neutrino oscillations

Journal Article Beun, J ; McLaughlin, G C ; Surman, R ; ... - Physical Review. D, Particles Fields

We investigate nucleosynthesis in the supernova post-core bounce neutrino-driven wind environment in the presence of active-sterile neutrino transformation. We consider active-sterile neutrino oscillations for a range of mixing parameters: vacuum mass-squared differences of 0.1 eV{sup 2}{<=}{delta}m{sup 2}{<=}100 eV{sup 2}, and vacuum mixing angles of sin{sup 2}2{theta}{sub v}{>=}10{sup -4}. We find a consistent r-process pattern for a large range of mixing parameters that is in rough agreement with the halo star CS 22892-052 abundances and the pattern shape is determined by fission cycling. We find that the allowed region for the formation of the r-process peaks overlaps the liquid scintillator neutronmore »« less

Studies of neutrino asymmetries generated by ordinary-sterile neutrino oscillations in the early Universe and implications for big bang nucleosynthesis bounds

Journal Article Foot, R ; Volkas, R R - Physical Review, D

Ordinary-sterile neutrino oscillations can generate a significant lepton number asymmetry in the early Universe. We study this phenomenon in detail. We show that the dynamics of ordinary-sterile neutrino oscillations in the early Universe can be approximately described by a single integrodifferential equation which we derive from both the density matrix and Hamiltonian formalisms. This equation reduces to a relatively simple ordinary first-order differential equation if the system is sufficiently smooth (static limit). We study the conditions for which the static limit is an acceptable approximation. We also study the effect of the thermal distribution of neutrino momenta on the generationmore »« less

Impact of neutrino flavor oscillations on the neutrino-driven wind nucleosynthesis of an electron-capture supernova

Journal Article Pllumbi, Else ; Janka, Hans-Thomas ; Hüdepohl, Lorenz ; ... - Astrophysical Journal

Neutrino oscillations, especially to light sterile states, can affect nucleosynthesis yields because of their possible feedback effect on the electron fraction (Y{sub e}). For the first time, we perform nucleosynthesis calculations for neutrino-driven wind trajectories from the neutrino-cooling phase of an 8.8 M{sub ⊙} electron-capture supernova (SN), whose hydrodynamic evolution was computed in spherical symmetry with sophisticated neutrino transport and whose Y{sub e} evolution was post-processed by including neutrino oscillations between both active and active–sterile flavors. We also take into account the α-effect as well as weak magnetism and recoil corrections in the neutrino absorption and emission processes. We observemore »« less

Subdominant Dark Matter sterile neutrino resonant production in the light of PLANCK

Journal Article Popa, L. A. ; Tonoiu, D., E-mail: lpopa@spacescience.ro, E-mail: tonoiud@spacescience.ro - Journal of Cosmology and Astroparticle Physics

Few independent detections of a weak X-ray line at an energy of ∼ 3.5 keV seen toward a number of astrophysical sites have been reported. If this signal will be confirmed to be the signature of decaying DM sterile neutrino with a mass of ∼ 7.1 keV, then the cosmological observables should be consistent with its properties. In this paper we make a coupled treatment of the weak decoupling, primordial nucleosynthesis and photon decoupling epochs in the sterile neutrino resonant production scenario, including the extra radiation energy density via N{sub eff}. We compute the radiation and matter perturbations including the full resonancemore »« less
