  • Discovery of Cl-34g,Cl-m(p,gamma)Ar-35 resonances activated at classical nova temperatures 

    Fry, C.; Wrede, Christopher; Bishop, Shawn M.; Brown, B. A.; Chen, Alan A.; Faestermann, Thomas; Hertenberger, R.; Parikh, Anuj Ramesh; Perez Loureiro, D; Wirth, Hans Friedrich; Garcia, A.; Ortez, Ronaldo (2015-01-13)
    Article
    Open Access
    Background: The thermonuclear Cl-34g,Cl-m(p,gamma)Ar-35 reaction rates are unknown due to a lack of experimental nuclear physics data. Uncertainties in these rates translate to uncertainties in S-34 production in models ...
  • Measurement of very low (alpha,n) cross sections of astrophysical interest 

    Taín, J.L.; Jordán, D.; Agramunt Ros, Jorge; Caballero-Folch, R.; Calviño Tavares, Francisco; Cortés Rossell, Guillem Pere; Longland, Richard; Parikh, Anuj Ramesh (Institute of Physics (IOP), 2013)
    Conference report
    Open Access
    The reactions C-13(alpha,n)O-16 and Ne-22(alpha,n)Mg-25 are the primary sources of neutrons for the astrophysical s-process. The feasibility of cross section measurements within the respective Gamow windows is discussed ...
  • Non-extensive statistics to the cosmological lithium problem 

    Hou, S.Q.; He, J.J.; Parikh, Anuj Ramesh (2017-01-11)
    Article
    Open Access
    Big Bang nucleosynthesis (BBN) theory predicts the abundances of the light elements D, 3He, 4He, and 7Li produced in the early universe. The primordial abundances of D and 4He inferred from observational data are in good ...
  • Reaction Rates of 64Ge(p,g)65As and 65As(p,g)66Se and the Extent of Nucleosynthesis in Type I X-Ray Bursts 

    Lam, Y.H.; He, J.J.; Parikh, Anuj Ramesh (2016-02)
    Article
    Open Access
    The extent of nucleosynthesis in models of type I X-ray bursts (XRBs) and the associated impact on the energy released in these explosive events are sensitive to nuclear masses and reaction rates around the 64Ge waiting ...
  • Recent advances in the modelling of classical novae and type I X-ray bursts 

    José Pont, Jordi; Casanova Bustamante, Jordi; Parikh, Anuj Ramesh; García-Berro Montilla, Enrique (2012)
    Article
    Open Access
    Classical nova outbursts and type I X-ray bursts are thermonuclear stellar explosions driven by charged-particle reactions. Extensive numerical simulations of nova explosions have shown that the accreted envelopes attain ...
  • Spectroscopy of Ne 19 for the thermonuclear O 15 (alfa,gamma) Ne 19 and F 18 (pi,alfa) O 15 reaction rates 

    Parikh, Anuj Ramesh; Laird, A.M.; de Séréville, N (2015-11-20)
    Article
    Open Access
    Uncertainties in the thermonuclear rates of the O15(a,¿)19Ne and 18F(p,a)15O reactions affect model predictions of light curves from type I x-ray bursts and the amount of the observable radioisotope F18 produced in classical ...
  • The 20Ne(d,p)21Ne transfer reaction in relation to the s-process abundances 

    Nsangu, C.T.; Laird, A.M.; Parikh, Anuj Ramesh (Institute of Physics (IOP), 2016-01)
    Article
    Open Access
    A study of the 20Ne(d,p)21Ne transfer reaction was performed using the Quadrupole Dipole Dipole Dipole (Q3D) magnetic spectrograph in Garching, Germany. The experiment probed excitation energies in 21Ne ranging from 6.9 ...
  • The unreasonable effectiveness of experiments in constraining nova nucleosynthesis 

    Parikh, Anuj Ramesh (EDP Sciences, 2013)
    Conference lecture
    Open Access
    Classical nova explosions arise from thermonuclear ignition in the envelopes of accreting white dwarfs in close binary star systems. Detailed observations of novae have stimulated numerous studies in theoretical astrophysics ...
  • Toward concordance of Ex and JPi values for proton unbound 31S states 

    Parikh, Anuj Ramesh; Wrede, Christopher; Fry, C. (2016-09)
    Article
    Open Access
    Nucleosynthesis in classical novae on oxygen-neon white dwarfs is sensitive to the poorly constrained thermonuclear rate of the 30P(p,¿)31S reaction. In order to improve this situation, a variety of experiments have been ...
