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
Accés obertBackground: 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 Enríquez, José Luis; 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)
Text en actes de congrés
Accés obertThe 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
Accés obertBig 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
Accés obertThe 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
Accés obertClassical 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
Accés obertUncertainties 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
Accés obertA 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)
Comunicació de congrés
Accés obertClassical 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
Accés obertNucleosynthesis 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 ...
